Although the script is lengthy, it has been made to be super easy to setup and use. There are some prerequisites and instructions at the top of the script. After installing the prerequisites and configuring the variables for your environment, simply run:

.\Clean-WSUS.ps1 -FirstRun

and then

.\Clean-WSUS.ps1 -InstallTask

If you wish to view or increase the Application Pool Memory Configuration, you must run it with the required switch. See Get-Help .\Clean-WSUS.ps1 -Examples

If you're having trouble, there's also a -HelpMe option that will create a log so you can send it to me for support.
