AuthorizationManager check failed when launching scripts in PowerShell

Recently, I received this error when trying to run a script on my Server 2008 R2 server.

AuthorizationManager check failed.

+ CategoryInfo : NotSpecified: (:) [], PSSecurityException

I was also unable to run the command set-executionpolicy remotesigned:
Set-ExecutionPolicy : Not found

  1. Open a command prompt "As Administrator"

  2. run "winmgmt /salvagerepository"

If /salvagerepository doesn't fix the WMI errors, you can disable the WMI service, reboot, rename the \wbem\repository folder, enable the WMI service and reboot again.
