WSUS Content Store drive is full and WSUS Cleanup Wizard fails

Updated August 1st, 2016


If the drive storing the WSUS Content Store fills up, the WSUS Cleanup Wizard may fail. This article will explain the cause and provide potential alternative solutions.


All versions of Patch Manager


If the WSUS Content Store is allowed to grow and fills the disk then failures will occur for various tasks including synchronizing future updates from Microsoft Update or publishing new Third Party Updates from Patch Manager.  If the disk is sufficiently full the WSUS Cleanup Wizard will fail.  The reason for this failure is that the WSUS Cleanup Wizard writes to a log file and without sufficient space will be unable to complete.



Expand the disk.

  • If this is a VM, or you are otherwise able to do so, expanding the disk that is full will allow the WSUS Cleanup Wizard to complete successfully.
    • Expanding the disk may be a solution if you believe that all of the updates present are necessary.l
    • Expanding the disk by 5-10 GB should allow the WSUS Cleanup Wizard to perform the task and write the log and allow the cleanup to complete.

Cleanup the WSUS Content Store manually.
