WSUS Part 3: Tuning you WSUS server with Powershell

WSUS Server cleanup

Because the WSUS server uses a lot of storage, it can be useful to clean the WSUS server regularly. This works well if you starts with cleaning regularly after a clean install. When you wait to long and the WSUS server becomes bigger and bigger, it will take a long time to clean the server. In PowerShell you can use this cmdlet:

Invoke-WsusServerCleanUp 

Parameters:

-CleanupObsoleteComputers

Specifies that the cmdlet deletes obsolete computers from the database.

-CleanupObsoleteUpdates

Specifies that the cmdlet deletes obsolete updates from the database.

-CleanupUnneededContentFiles

Specifies that the cmdlet deletes unneeded update files.

-CompressUpdates

Specifies that the cmdlet deletes obsolete revisions to updates from the database.

-DeclineExpiredUpdates

Specifies that the cmdlet declines expired updates.

-DeclineSupersededUpdates

Specifies that the cmdlet declines superseded updates.

-UpdateServer

Specifies the object that contains the WSUS server. This value is obtained by calling the Get-WsusServer cmdlet and passing the resulting IUpdateServer object into this cmdlet.

Example I use for my script:

Invoke-WsusServerCleanUp -CleanUpObsoleteUpdates -CleanupUnneededContentFiles -CompressUpdates
