PowerShell says "execution of scripts is disabled on this system."

Question

I am trying to run a cmd file that calls a PowerShell script from cmd.exe, but I am getting this error:

Management_Install.ps1 cannot be loaded because the execution of scripts is disabled on this system.

I ran this command:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

When I run Get-ExecutionPolicy from PowerShell, it returns Unrestricted.

Get-ExecutionPolicy

Output:

Unrestricted

Its worth pointing out that Execution Policy carries several scopes, and running PowerShell in different ways can get you different policies. To view the list of policies, run Get-ExecutionPolicy -List. – Vigesimal

All policy explanations are here. – Subtropical

Answer 1

If you're using Windows Server 2008 R2 then there is an x64 and x86 version of PowerShell both of which have to have their execution policies set. Did you set the execution policy on both hosts?

As an Administrator, you can set the execution policy by typing this into your PowerShell window:

Set-ExecutionPolicy RemoteSigned

For more information, see Using the Set-ExecutionPolicy Cmdlet.

When you are done, you can set the policy back to its default value with:

Set-ExecutionPolicy Restricted

You may see an error:

Access to the registry key
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. 
To change the execution policy for the default (LocalMachine) scope, 
  start Windows PowerShell with the "Run as administrator" option. 
To change the execution policy for the current user, 
  run "Set-ExecutionPolicy -Scope CurrentUser".

So you may need to run the command like this (as seen in comments):

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Intorsion

Set-ExecutionPolicy Restricted seems to be the way to undo it if you want to put the permissions back to as they were: technet.microsoft.com/en-us/library/ee176961.aspx. The temporary bypass method by @Jack Edmonds looks safer to me: powershell -ExecutionPolicy ByPass -File script.ps1 – Sardonic

Set-ExecutionPolicy RemoteSigned cannot be the first line in your script. If it is, highlight it and run selected only INITIALLY before running the rest of your script. – Fann

I came across a similar question on SF site, "Powershell execution policy within SQL Server” asked Oct 10 '14. The answers there included Get-ExecutionPolicy -List which helped me to see the different scopes. The cmd Get-ExecutionPolicy does not show all the scopes. Import-Module SQLPS is now working with policies changed as follows: {Undefined- Process,MachinePolicy,UserPolicy,}; {RemoteSigned- CurrentUser, LocalMachine}. – Dupre

If I do this, does the change last for only the duration of the current PowerShell? Or is it bigger than that? – Merkle

Also be sure to execute it in a direct Powershell shell, and not a cmd shell. It won't take effect otherwise. – Selfexplanatory

If you need it less restricted than RemoteSigned, you can also set it to Unrestricted. – Photon

After this Command get Success Set-ExecutionPolicy RemoteSigned -Scope CurrentUser – Ladylove

@SharpC, it is Undefined that reverts the policy in a given scope to its default; e.g., Set-ExecutionPolicy -Scope CurrentUser Undefined -Force. While on workstation editions of Windows using Restricted has the same effect, note that - at least nowadays - server editions default to RemoteSigned. – Zolly

In powershell # To check the current execution policy, use the following command: Get-ExecutionPolicy # To change the execution policy to Unrestricted, which allows running any script without digital signatures, use the following command: Set-ExecutionPolicy Unrestricted # This solution worked for me, but be careful of the security risks involved. – Winzler

this line works for me, thanks. "Set-ExecutionPolicy RemoteSigned -Scope CurrentUser" – Envisage

Answer 2

You can bypass this policy for a single file by adding -ExecutionPolicy Bypass when running PowerShell

powershell -ExecutionPolicy Bypass -File script.ps1

Reube

This is also really handy if you're on a non-administrator account. I made a shortcut to %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy ByPass on my taskbar. – Towline

Note that Microsoft Technet stylizes it as "Bypass", not "ByPass". See: technet.microsoft.com/nl-nl/library/hh849812.aspx – Baywood

This doesn't work for me, I get the same permission denied as if I called it normally. Calling a ps1 from a .bat by doing type script.ps1 | powershell - does work though. – Elga

The purpose to Execution Policy is to prevent people from double-clicking a .ps1 and accidentally running something they didn't mean to. This would happen with .bat files – Connect

Perfect solution for single file execution, without changing policies and lowering security. – Irrefrangible

A parameter cannot be found that matches parameter name 'File' Command: Set-ExecutionPolicy -ExecutionPolicy Bypass -File .\file.ps1 – Florence

powershell -ExecutionPolicy Bypass -File .\file.ps1 This will work @Devil'sAdvocate – Jemima

This worked for me but my antivirus flagged it as malicious and quarantined it. I had to add an exception. – Vanya

This doesn't work for me when using winsw to run the ps1 file as a service. I get the same error in the log. – Cyndie

How do I do that permanently for one file – Cellist

Answer 3

I had a similar issue and noted that the default cmd on Windows Server 2012, was running the x64 one.

For Windows 11, Windows 10, Windows 7, Windows 8, Windows Server 2008 R2 or Windows Server 2012, run the following commands as Administrator:

x86 (32 bit)
Open C:\Windows\SysWOW64\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned

x64 (64 bit)
Open C:\Windows\system32\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned

You can check mode using

• In CMD: echo %PROCESSOR_ARCHITECTURE%
• In Powershell: [Environment]::Is64BitProcess

References:
MSDN - Windows PowerShell execution policies
Windows - 32bit vs 64bit directory explanation

Eidolon

Is it possible to run these via powershell passing the arguments to the cmd executable so as to automate the configuration? – Cyndie

@Cyndie Could you not run a .cmd file with the above command, before executing the powershell? You can also set this at the policy level if you need to, although I have not done that. – Eidolon

Answer 4

Most of the existing answers explain the How, but very few explain the Why. And before you go around executing code from strangers on the Internet, especially code that disables security measures, you should understand exactly what you're doing. So here's a little more detail on this problem.

From the TechNet About Execution Policies Page:

Windows PowerShell execution policies let you determine the conditions under which Windows PowerShell loads configuration files and runs scripts.

The benefits of which, as enumerated by PowerShell Basics - Execution Policy and Code Signing, are:

• Control of Execution - Control the level of trust for executing scripts.
• Command Highjack - Prevent injection of commands in my path.
• Identity - Is the script created and signed by a developer I trust and/or a signed with a certificate from a Certificate Authority I trust.
• Integrity - Scripts cannot be modified by malware or malicious user.

To check your current execution policy, you can run Get-ExecutionPolicy. But you're probably here because you want to change it.

To do so you'll run the Set-ExecutionPolicy cmdlet.

You'll have two major decisions to make when updating the execution policy.

Execution Policy Type:

• Restricted^† - No Script either local, remote or downloaded can be executed on the system.
• AllSigned - All script that are ran require to be digitally signed.
• RemoteSigned - All remote scripts (UNC) or downloaded need to be signed.
• Unrestricted - No signature for any type of script is required.

Scope of new Change

• LocalMachine^† - The execution policy affects all users of the computer.
• CurrentUser - The execution policy affects only the current user.
• Process - The execution policy affects only the current Windows PowerShell process.

^{† = Default}

For example: if you wanted to change the policy to RemoteSigned for just the CurrentUser, you'd run the following command:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Note: In order to change the Execution policy, you must be running PowerShell As Administrator. If you are in regular mode and try to change the execution policy, you'll get the following error:

Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option.

If you want to tighten up the internal restrictions on your own scripts that have not been downloaded from the Internet (or at least don't contain the UNC metadata), you can force the policy to only run signed scripts. To sign your own scripts, you can follow the instructions on Scott Hanselman's article on Signing PowerShell Scripts.

Note: Most people are likely to get this error whenever they open PowerShell because the first thing PowerShell tries to do when it launches is execute your user profile script that sets up your environment however you like it.

The file is typically located in:

%UserProfile%\My Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1

You can find the exact location by running the PowerShell variable

$profile

If there's nothing that you care about in the profile, and don't want to fuss with your security settings, you can just delete it and PowerShell won't find anything that it cannot execute.

Kitchener

I feel like it's important to note that while execution policy is a security measure, it's not one that's intended to prevent users from executing PowerShell code. Execution policy is something that's intended to protect your scripts and determine who wrote, modifed or approved them and that's all. It's trivial to get around execution policy with something as simple as Get-Content .\MyFile.ps1 | powershell.exe -NoProfile -. – Vigesimal

Given the existence of -ExecutionPolicy ByPass though, what is the purpose of this policy anyway? Is it just to prevent users from accidentally opening a powershell console and running a malicious script? Couldn't the attacker just use an executable or a batch script if they wanted to get around this? Even after reading @BaconBits comment I'm not quite sure what scenario this policy is meant to prevent... – Solly

@Solly Say I have a task that runs a script on a network share. When I invoke my script, I want my process to verify that the script is signed. I want my code to double check that the script I'm going to run is the code I trust to run. I don't care if you can run my code. Stopping that is access rights' job. I just want to prevent you from making me run code that I didn't write. Access rights means the operating system prevents you from modifying my code when you're logged on. Code signing and execution policy means my script hasn't been modified when I go to run it. – Vigesimal

how about showing how to sign the script rather then how to disable security? Is that an option? – Shaeshaef

@gman, I think that's a fair point. To crowdsource the work, you can certainly add that answer or append to this one. – Kitchener

@Solly If there are similar policies to prevent running unsigned exe and/or forbidding running bat scripts, then that would prevent a user from accidentally running any unsigned code, which could be useful. Running it then becomes intentional and clear that this is unsigned code (which of course is not really super helpful in itself to determine if you should run it...). – Shatzer

Answer 5

We can get the status of current ExecutionPolicy by the command below:

Get-ExecutionPolicy

By default it is Restricted. To allow the execution of PowerShell scripts we need to set this ExecutionPolicy either as Unrestricted or Bypass.

We can set the policy for Current User as Bypass by using any of the below PowerShell commands:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted -Force

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force

Unrestricted policy loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs.

Whereas in Bypass policy, nothing is blocked and there are no warnings or prompts during script execution. Bypass ExecutionPolicy is more relaxed than Unrestricted.

Daisey

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force; AKA quick and dirty way to tell VS2015 to stop complaining and run my bloody script. thanks. lifesaver. – Please

The trailing semicolons on the ends of your commands are superfluous. – Tauto

Answer 6

Also running this command before the script also solves the issue:

Set-ExecutionPolicy Unrestricted

Vodka

-1 - Follow the principle of least permission. At least set the policy to RemoteSigned before removing all restrictions on your security policy. If that doesn't work, then re-assess what your pain points are and why it isn't working. You can set unrestricted as a last resort, but it shouldn't be your starting point. – Kitchener

Thanks for pointing out this option too. With all due respect to security needs for production purposes, in the times when quick prototyping ability demand is so high, all the policies and security really get in the way of getting stuff done. – Flagelliform

Regarding the comment re prototyping, I'm afraid that this is why crappy code gets into production. Of course this is just a trivial example, but if you can't solve something this trivial during development, it's a worry for release. Also, for bespoke code, and if you can, know the target environment - we set the majority of our internal systems as Remotesigned. – Telles

Answer 7

If you are in an environment where you are not an administrator, you can set the Execution Policy just for you (CurrentUser), and it will not require administrator.

You can set it to RemoteSigned:

Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "RemoteSigned"

or Unrestricted:

Set-ExecutionPolicy -Scope "CurrentUser" -ExecutionPolicy "Unrestricted"

You can read all about Getting and Setting Execution policy in the help entries:

Help Get-ExecutionPolicy -Full
Help Set-ExecutionPolicy -Full

Supralapsarian

Worked great for me in Windows 8, even when Set-ExecutionPolicy Unrestricted as an admin didn't seem to "unrestrict" enough to actually help. – Cranston

I believe what you may be experiencing is a GPO or something else overwriting your setting of the "LocalMachine" level of ExecutionPolicy. You cannot overwrite what a Domain Policy has in place with the Set-ExecutionPolicy command. However, but setting the "CurrentUser" level of access, you and only you will have the specified Execution Policy. This is because the computer looks at the CurrentUser for execution policy before it looks at the LocalMachine setting. – Supralapsarian

Answer 8

In Windows 7:

Go to Start Menu and search for "Windows PowerShell ISE".

Right click the x86 version and choose "Run as administrator".

In the top part, paste Set-ExecutionPolicy RemoteSigned; run the script. Choose "Yes".

Repeat these steps for the 64-bit version of Powershell ISE too (the non x86 version).

I'm just clarifying the steps that @Chad Miller hinted at. Thanks Chad!

Ky

In Windows 8 too, this worked. I set Set-ExecutionPolicy RemoteSigned; in Windows Powershell only, by running it as administrator. Didn't need to repeat the procedure for x86 version. – Ellington

Answer 9

RemoteSigned: all scripts you created yourself will be run, and all scripts downloaded from the Internet will need to be signed by a trusted publisher.

OK, change the policy by simply typing:

Set-ExecutionPolicy RemoteSigned

Regardful

As recommended in other posts: it's wise to include "-Scope CurrentUser" for a more secure policy, when that makes sense. – Sostenuto

Answer 10

First, you need to open the PowerShell window and run this command.

set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Then it will ask you to confirm. Type Y and press Enter.

When you run this command, you can see that your system has set all policies for the current user as remotely. It will take a few seconds to complete this process.

The image will be shown like below:

To check if the execution policy has set. Type:

Get-ExecutionPolicy

If it was set, the output would be like this:

Answer 11

I'm using Windows 10 and was unable to run any command. The only command that gave me some clues was this:

[x64]

1. Open C:\Windows\SysWOW64\cmd.exe [as administrator]
2. Run the command> powershell Set-ExecutionPolicy Unrestricted

But this didn't work. It was limited. Probably new security policies for Windows10. I had this error:

Set-ExecutionPolicy: Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of...

So I found another way (solution):

1. Open Run Command/Console (Win + R)
2. Type: gpedit.msc (Group Policy Editor)
3. Browse to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Powershell.
4. Enable "Turn on Script Execution"
5. Set the policy as needed. I set mine to "Allow all scripts".

Now open PowerShell and enjoy ;)

Answer 17

Setting the execution policy is environment-specific. If you are trying to execute a script from the running x86 ISE you have to use the x86 PowerShell to set the execution policy. Likewise, if you are running the 64-bit ISE you have to set the policy with the 64-bit PowerShell.

I have also faced a similar issue. Try this.

As I'm using Windows, I followed the steps as given below. Open a command prompt as an administrator and then go to this path:

Look for the file ng.ps1 in this folder (directory) and then delete it (del ng.ps1).

You can also clear npm cache after this though it should work without this step as well.

Answer 24

There's great information in the existing answers, but let me attempt a systematic overview:

Context

PowerShell's effective execution policy applies:

• to PowerShell code stored in files, which means regular script files (.ps1), script module files (.psm1), as well as formatting and type-extension files (.psm1xml).

  • It does not apply to:
    • calls to (binary) cmdlets (e.g., Get-ChildItem)
    • commands submitted interactively or passed to the PowerShell CLI via the
      -Command parameter (unless these commands directly or indirectly call script files as defined above).

• on Windows only (that is, on Unix-like platforms (Linux, macOS) execution policies do not apply and no restrictions are placed on executing PowerShell code)

On workstation editions of Windows, script-file execution is disabled by default (policy Restricted), requiring either a persistent modification of the policy to enable it, or a current-process-only modification such as via the -ExecutionPolicy parameter when calling the PowerShell CLI, powershell.exe (Windows PowerShell edition) / pwsh.exe (PowerShell (Core) edition).

Execution policies are maintained separately:

• for the two PowerShell editions:

  • the legacy, Windows-only, ships-with-Windows Windows PowerShell edition (whose latest and last version is v5.1.x)
  • the modern, cross-platform, install-on-demand PowerShell (Core) edition (v6+).

• for the 32-bit and 64-bit versions of Windows PowerShell (both of which are preinstalled)

  • Note: If you were to install 32-bit and 64-bit versions of PowerShell (Core) side by side (which would be unusual), only the LocalMachine scope would be bitness-specific.

For a given edition / bitness combination of PowerShell, the execution policies can be set in multiple scopes, but there's only ever one effective policy, based on precedence rules - see below.

Details

• In PowerShell on Windows, script-file execution is disabled by default in workstation editions of Windows (on Unix, execution policies do not apply); that is, the default execution policy in workstation editions of Windows is Restricted, whereas in server editions, it is RemoteSigned; see the conceptual about_Execution_Policies help topic for a description of all available policies.

• To set a (local) policy that permits script execution, use Set-ExecutionPolicy. There are three scopes that Set-ExecutionPolicy can target, using the -Scope parameter (see below); changing the LocalMachine scope requires elevation (running as admin).

  • To unset a previously set policy in a given scope, use Undefined

• A frequently used policy that provides a balance between security and convenience is RemoteSigned, which allows local scripts - including from network shares - to execute without containing a signature, while requiring scripts downloaded from the internet to be signed (assuming that the downloading mechanism marks such as scripts as internet-originated, which web browsers do by default). For instance, to set the current user's execution policy to RemoteSigned, run the following:

  Set-ExecutionPolicy -Scope CurrentUser RemoteSigned -Force
  

• The PowerShell CLI (powershell.exe for Windows PowerShell, pwsh.exe for PowerShell (Core), v6+) accepts a process-specific -ExecutionPolicy <policy> argument too, which is often used for ad-hoc policy overrides (only for the process being created, the equivalent of Set-ExecutionPolicy -Scope Process ..); e.g.:

  pwsh.exe -ExecutionPolicy RemoteSigned -File someScript.ps1
  

• Important:

  • Execution policies can also be set via Group Policy Objects (GPOs), in which case they can not be changed or overridden with Set-ExecutionPolicy or via the CLI: see about_Group_Policy_Settings

  • Execution policies can be set in various scopes, and which one is in effect is determined by their precedence (run Get-ExecutionPolicy -List to see all scopes and their respective policies), in descending order:

    • MachinePolicy (via GPO; cannot be overridden locally)^[1]
    • UserPolicy (via GPO; cannot be overridden locally)^[1]
    • Process (current process only; typically set ad-hoc via the CLI)
    • CurrentUser (as set by Set-ExecutionPolicy)
    • LocalMachine (as set by Set-ExecutionPolicy, with admin rights)

---

^{[1] This applies to domain-wide GPOs. Local GPOs can be modified locally, namely via gpedit.msc or directly via the registry.}

Solution for “cannot be loaded because running scripts is disabled on this system“: How do you enable running scripts is disabled on this system error? To fix this issue, we have to set the execution policy, so that the PowerShell script runs on the particular machine. Here is to permit PowerShell script execution:

1. Open PowerShell Console by selecting “Run as Administrator” and get the execution Policy with the command: Get-ExecutionPolicy to get the current policy applied, such as “Restricted”.

2. Set the execution Policy with the following command: Set-ExecutionPolicy RemoteSigned

3. Type “Y” when prompted to proceed.

Yalonda

Answer 34

In PowerShell 2.0, the execution policy was set to disabled by default.

From then on, the PowerShell team has made a lot of improvements, and they are confident that users will not break things much while running scripts. So from PowerShell 4.0 onward, it is enabled by default.

In your case, type Set-ExecutionPolicy RemoteSigned from the PowerShell console and say yes.

I was facing a similar kind of error:

cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

And did this and it is fixed:

1. Open Windows powershell as administrator.
2. RUn command: powershell Set-ExecutionPolicy RemoteSigned
3. Check status: Get-ExecutionPolicy

Empiricism

Answer 42

If you're here because of running it with Ruby or Chef and using `` system execution, execute as follows:

`powershell.exe -ExecutionPolicy Unrestricted -command [Environment]::GetFolderPath(\'mydocuments\')`

That command is for getting "MyDocuments" Folder.

-ExecutionPolicy Unrestricted does the trick.

I hope it's helpful for someone else.

Should the enclosing `` really be there? – Vick

Answer 43

Several answers point to execution policy. However some things require "runas administrator" also. This is safest in that there is no permanent change to execution policy, and can get past administrator restriction. Use with schedtask to start a batch with:

    runas.exe /savecred /user:administrator powershell -ExecutionPolicy ByPass -File script.ps1

from both Jack Edmonds above, and Peter Mortensen / Dhana of post How to run an application as "run as administrator" from the command prompt?

Answer 44

You can use a special way to bypass it:

Get-Content "PS1scriptfullpath.ps1" | Powershell -NoProfile -

It pipes the content of PowerShell script to powershell.exe and executes it bypassing the execution policy.

Gould

What is "special" about this way? What if arguments need to be passed to PS1scriptfullpath.ps1? When/Why would one use this instead of directly launching a new PowerShell process with an overridden execution policy as shown in this earlier answer or using -Command "PS1scriptfullpath.ps1"? – Nealon

Answer 45

Delete the ng.ps1 file in C:\Users[your user]\AppData\Roaming\npm.

And delete the npm cache file in C:\Users\USER\AppData\Roaming.

Answer 46

in my case it happened because i use PowerShell and I should use the cmd prompt

Anesthetist

Answer 47

It happened to me as well. For me, the solution was simple. I didn't realize that the path in the command prompt to run Nodemon was different to where I installed the package.

So it gave me the same error that you've mentioned.

Changing my path resolved it.

Upthrow

What is "nodemon" and, since the author of the question hasn't indicated they're using it, how does it relate to this question? It's not clear what the problem and solution with the path were, either. Perhaps this question is more appropriate for the solution you're trying to provide. – Nealon

Answer 48

For a downloaded file, right-click → Properties

Then click Unblock and click OK. Then run the PowerShell script and it will no longer complain about not being able to run.

Gisela

Answer 49

A best practice is to read the script's code and verify it's safe before using the Unblock-File cmdlet. The Unblock-File cmdlet unblocks scripts so they can run, but doesn't change the execution policy. PS> Unblock-File -Path .\Start-ActivityTracker.ps1

Set-ExecutionPolicy RemoteSigned

‘Running Scripts is Disabled’ Error When Deploying on Vercel

Indonesian

Answer 51

Open cmd instead of powershell. This helped for me...

Westnorthwest

The command prompt used in the question already is cmd.exe: "I am trying to run a cmd file that calls a PowerShell script from cmd.exe ...". This is why the command is prefixed with powershell: powershell .\Management_Install.ps1 1. Otherwise, "fixing" a PowerShell error by simply not using PowerShell is not a solution. – Nealon

right, my fault. Did not see it. "Don't use powershell" is a bad solution to this problem, although it's a very good solution to a happier life. – Westnorthwest

Answer 52

Run Set-ExecutionPolicy RemoteSigned command

Rickety

This is identical to numerous other answers suggesting the same exact command, one of which is the highest-voted, accepted answer. You really should check that you're not duplicating other answers before posting your own.

Answer 53

Run cmd or powershell as "Run as administrator"

Toile

It isn't to do with running as an admin or not. – Thoughtout

Answer 54

Open the PowerShell window as an Administrator. It will work.

Anatolian

It did not works. However, running powershell Set-ExecutionPolicy RemoteSigned did works. – Estus
