Powershell: ExecutionPolicy is unable to be read/set
I was trying to run a powershell script (which I have run before) and received the following error:
Authorizationmanager Check Failed
I figured it was the Execution Policy, so ran:
Set-ExecutionPolicy Unrestricted
I then received:
Set-ExecutionPolicy : Initialization failure
At line:1 char:20
+ set-executionpolicy <<<< unrestricted
+ CategoryInfo : NotSpecified: (:) [Set-ExecutionPolicy], ManagementException
+ FullyQualifiedErrorId : System.Management.ManagementException,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand
The same initialization error occurs for Get-ExecutionPolicy
Some basic commands seem to work fine, such as:
Write-Output "hi"
Can anyone suggest a fix?
Note: This is on Windows XP
Update: If I run the contents of ascript from within the powershell command prompt, it works. I only get the errors if it is run as a script. Also, Get-ExecutionPolicy and Set-ExecutionPolicy still fail from within the powershell prompt.
确保您以管理员身份运行控制台[右键单击]，然后单击“以管理员身份运行”，当您运行Set-ExecutionPolicy Unrestricted 。
The source of the error was due to a problem with the WMI repository. I was able to repair the repository running the following command:
Note : This is for Windows XP
rundll32 wbemupgd, UpgradeRepository
Once this was run, I was successfully able to execute Get-ExecutionPolicy, and other powershell scripts again.
A couple of links that detail repairing the WMI Repository.
Another very common case (I think this only applies post-XP), is where the .ps1 file has been 'blocked' after being downloaded from an untrusted location.
Solution: open the 'Properties' of the file in Windows Explorer, and on the 'General' tab click 'Unblock', then 'Apply' or 'OK'.
