I'm running powershell 3 on Windows 8. It was working fine until yesterday. Now I can't use any cmdlet or other commands. Every single time I get a "X is not recognized as the name of a cmdlet, function, script file, or operable program." If I run powershell with the -v 2 switch it seems to function allright, but many of the new cmdlets, for Active Directory for instance, are not available.
I've logged out and back in and rebooted my machine. Nothing works. Is there any way of reinstalling Powershell 3.
