How to reset Powershell to the default settings

powershell

I have changed many powershell policies, such as the Execution policy for running scripts. Is there a way to get everything back to the default settings when OS was installed?

Best Answer

There is a PowerShell profile file, usually at C:\Users\UserA\Documents\WindowsPowerShell that you can edit/remove some customization entries.

When it comes to "resetting services" that is probably something that can be done manually.

e.g. for Execution Policy

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Undefined

Additionally, check C:\Users\UserA\Documents\PowerShell\powershell.config.json you can actually changed execution policy from there

To do the signing you can use the Set-AuthenticodeSignature cmdlet. This, of course, requires a certificate. If you have a Certificate Authority (unlikely) that will be able to create a code signing certificate. Otherwise there are various tools to create a self-signed certificate.

You install the certificate in your certificate store (open the .cer or .pfx file in Windows Explorer to do this), and then pass it to Set-AuthenticodeSignature (the cert: provider/drive gives access to certificates in your store).

Use

help about_signing

or the online version of that help topic for details (including creating a self-signed certificate using the Windows SDK tools^[1]).

^[1] I assume this is the big download you're referring to: you can just install the bits you need, or make use of other tools (OpenSSL includes certificate generation). Getting the SDK is, for this purpose, a one-off activity.

How to Enable Execution of PowerShell Scripts

Start Windows PowerShell with the "Run as Administrator" option. Only members of the Administrators group on the computer can change the execution policy.
Enable running unsigned scripts by entering:
```
set-executionpolicy remotesigned
```

This will allow running unsigned scripts that you write on your local computer and signed scripts from Internet.
