Hey all,
I've just come across this issue with Windows 8.1; I installed the Windows Management Framework November 2014 preview so that I could take advantage of the OneGet/PowerShellGet benefits. However, now, even after removing the update from my system, I still seem to be experiencing an error pertaining to the CIM server. I get "invalid namespace" whenever I attempt to use the NetSecurity, Hyper-V, or any other cmdlet that requires access to a CIM server. What did I do here? (I can run any of these commands on my Windows server 2012 R2 server just fine.) If you need more information, please feel free to ask. This issue's been driving me bonkers for the past few days though. Thanks, guys.
