WSUS automated Cleanup

This script performs the cleanup tasks done by the WSUS cleanup wizard. Because it is a script, it can be automated (for example, via the Windows Task Scheduler). It also provides extended support for computer cleanup, allowing one to specify the number of days of not hearing from the computer before cleanup (default is 30 days), and to optionally skip deletion of computers that are still in Active Directory Directory Services (to avoid accidently removing computers that are still around but having trouble contacting the server). We recommend also performing SQL defragmentation sample script as part of WSUS cleanup.
Thx to ScriptingGuys.
