What is powershell execution policy?

What is powershell execution policy?

The PowerShell execution policy was created with the goal of being administrator-friendly while also being accessible to end users. The latter goal, more than the former, was a little more difficult to achieve, given that convenience is typically inversely proportionate to security.

Malicious VBS (Visual Basic Script) files disguised as useful bits of software have been sent around in emails on occasion. Unsuspecting users double-clicked the script files, falling for scams ranging from letting the script’s creator know you executed the script to giving the script’s creator entire access over your machine.
