  8. Computer Object Cleanup (configurable, with the default of deleting computer objects that have not synced within 30 days).

It will email the report out to you or save it to a file, or both.

Although the script is lengthy, it has been made to be super easy to setup and use so don't over think it. There are some prerequisites and instructions at the top of the script. After installing the prerequisites and configuring the variables for your environment (email settings only if you are accepting all the defaults), simply run:

.\Clean-WSUS.ps1 -FirstRun

If you wish to view or increase the Application Pool Memory Configuration, or run the Dirty Database Check, 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.

How to Upgrade

Upgrades are easy! Edit the variables to match your old set and run:

.\Clean-WSUS.ps1 -FirstRun

That's it! It really is THAT easy!
