Delete-temporary-files

This is a Powershell script that deletes temporary files, and LOG files from Windows.

How to use?

Start Windows PowerShell, or PowerShell 7 as administrator (Of course, if you don't have administrator priviliges, you can run it without eleveted priviliges, but some features may not work), and type this, to change the Execution Policy to Bypass for the Current Session:

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

(If you want to, you can change the Execution Policy to Unrestricted, instead of Bypass) Then, navigate to that directory, where you downloaded my script. Example: If you downloaded it to your Downloads folder, then type this:

cd $env:USERPROFILE\Downloads

($env:USERPROFILE is an environment variable, for your user profile, generated by Windows.) Then, type this, if you would like to run the basic DeleteTemporaryFiles script:

./DeleteTemporaryFiles5_1.ps1

Or, if you would like to run the script, that doesn't delete the Windows Update Temporary Files (It's recommended to run this, if an update is downloading, or installing.):

./NoWinUpdateTempDeletion_DeleteTemporaryFiles5_1.ps1

Then, answer the questions, and you're done.
