So you have a PowerShell script and you just want to run it without messing around with permissions, policies, signing it or any other crap. (Yes yes I know all those things are vital for system wide security but you’re in a hurry damn it!)
Right click PowerShell and run as administrator.
When the terminal is open run the following line:
Set-ExecutionPolicy RemoteSigned
When prompted type the letter A and press Enter (if applicable).
Run the below including “&” at start of line with reference to your script, i.e.
& “C:\YourTestDirectory\YourTestFile.ps1”
