As an alternative for re-installing PowerShell, you may try to change registry privileges

* Run: regedt32
* Right-Click > Permissions 
* Select, and add your account, grant it "Full Control" privileges

It helped me out, being "alternative" admin, on my machine, which was prepped by an operations admin
