How do I remove an environment variable in Windows PowerShell?

You can remove an environment variable in PowerShell using the Remove-Item cmdlet. For example, to remove a variable named 'MY_VAR', you would use: Remove-Item Env:MY_VAR.

Is there a way to check if the variable was removed?

Yes, you can check if the variable was removed by using Get-ChildItem Env: to list all environment variables. If 'MY_VAR' is not listed, it has been successfully removed.

Can I remove multiple environment variables at once?

Yes, you can remove multiple variables by using a loop. For example: foreach ($var in 'VAR1', 'VAR2') { Remove-Item Env:$var }.

What if I want to remove a user-specific environment variable?

For user-specific environment variables, you can use the same Remove-Item command, but ensure you're in the user context. The command remains the same.
