When I run powershell I get the error:
powershell has stopped working
There doesn't seem to be any relevant errors in the EventLog. I get this when I run powershell as an admin or a normal user.
When I try to re-install the Windows Management Framework I get the error:
A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file
This all seemed to happen when I tried to set a remote execution policy (to Unrestricted)
Any suggestions on how to resolve/troubleshoot?
