ExecutionPolicy is being asked everytime for running powershell script

Question

Facing small yet hectic issue because of execution policy.

A Powershell script was written to download SharePoint files using "sharepointclientcomponents".

But everytime we are executing it, an error is being thrown saying "Not Digitally Signed". For this, it is becoming mandatory to run "Set -ExecutionPolicy RemoteSigned" first everytime.

Is there any way to set this execution policy permanently so that we can schedule the code?

Your ideas would be a great help for us!

Thanks a ton in Advance!!!!

This is what we tried

    Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

Please try replacing the "Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass " in the first line of the code with "Set-ExecutionPolicy Bypass -Scope Process -Force ",it will help you set this execution policy permanently.

The following is the changed code:

Set-ExecutionPolicy Bypass  -Scope Process -Force
