I have run into this problem too. My case is as following:

%JAVA_HOME% = "%^JAVA_HOME%" = %C:\ProgramFiles\Java\jdk% C:\ProgramFiles\Java\jdk
I found their types of the registry value Path are different, so I checked whether the path is valid or not by the following command:
C:\Users\ssfang> where node java
C:\ProgramFiles\nodejs\node.exe
INFO: Could not find "java".
As a result, I reset the local (current user) environment by the following commands (Setx):
C:\Users\ssfang> setx PATH %^JAVA_HOME%\bin;"C:\ProgramFiles\nodejs"
SUCCESS: Specified value was saved.
C:\Users\ssfang> reg query HKEY_CURRENT_USER\Environment /v Path
HKEY_CURRENT_USER\Environment
Path REG_EXPAND_SZ %JAVA_HOME%\bin;C:\ProgramFiles\nodejs
C:\Users\ssfang> where node java

But, in the current process, it cannot propagate those changes to other running processes.
However, if you directly modify user environment variables in the Registry Editor,
those modifications to the environment variables do
not result in immediate change. For example, if you start another
Command Prompt after making the changes, the environment variables
will reflect the previous (not the current) values. The changes do not
take effect until you log off and then log back on.
To effect these changes without having to log off, broadcast a
WM_SETTINGCHANGE message to all windows in the system, so that any
interested applications (such as Windows Explorer, Program Manager,
Task Manager, Control Panel, and so forth) can perform an update.
See details at How to propagate environment variables to the system
Here, I give a powershell script to do it:
# powershell -ExecutionPolicy ByPass -File
# Standard, inline approach: (i.e. behaviour you'd get when using & in Linux)
# START /B CMD /C CALL "foo.bat" [args [...]]
# powershell -ExecutionPolicy ByPass -WindowStyle Hidden -File myScript.ps1

Add-Type @'
public class CSharp
{
public static void Method(object[] first, object[] second)
{
System.Console.WriteLine("Hello world");
}
}
'@
$a = 1..4;
[string[]]$b = "a","b","c","d";
[CSharp]::Method($a, $b);

if (-not ("MyClass" -as [type])) {
add-type @"

}
p.s. there's no Remove-Type; see this answer for more on how to best work around this limitation:

I think it will be wanted when debugging.
It is much simpler to close a tab in Console and open new one in PowerShell_ISE.exe or close PowerShell.exe.
Or
Start-Job -ScriptBlock {
param([uri]$url,$OutputDir)
# download and save pages
Invoke-RestMethod $url | Out-File "$OutputDir\$($url.Segments[-1])" -Force
