Why setting Powershell to set-executionpolicy remotesigned fails?
Solution 1:
You need to run powershell as an administrator to set the execution policy.
Once you've set it to remotesigned, you can run powershell as a regular user.
Solution 2:
Just go to the controll panel -> administrative tools -> Windows PowerShell Modules (opens a powershell) and type the usual set-executionpolicy remotesigned. That's it.
