Hey, let's face it, bad luck can strike the best of us, so if you find yourself in a position where your WSUS box is corrupt beyond repair, the regular uninstall isn't working and you have no choice but to do a complete removal and reinstallation then maybe these steps by Ellis George will help you get through it a little easier. These are specific to the SP1 version but should be OK for others as well.  Keep in mind that this is a measure of last resort and should only be used if you have no choice but to manually remove WSUS.  This will also remove WIDS so when you're done you'll be able to reinstall and start from scratch.

WARNING: Do Not Do This if you are running WSUS on SBS 2008!  SBS 2008 installs Sharepoint and WSUS on the same server and both applications store their database in Windows Internal Database. Removing Windows Internal Database (MICROSOFT##SSEE) using steps 6-8 will break Sharepoint and anything else you may have installed that relies on Windows Internal Database.


1. Please download and install the Windows Installer Cleanup Utility.  To install it simply run msicuu2.exe.

2. Once it is installed go to Start>All Programs>Windows Install Clean Up

3. Scroll through the options and highlight Microsoft Windows Server Update Services 3.0 SP1 (3.1.6001.65)


4. Click remove

5. Open a command prompt and run the following commands:

net stop wsusservice

net stop wsuscertserver

sc delete wsusservice

sc delete wsuscertserver

6. When complete, go back to the Windows Installer Cleanup Utility and highlight Windows Internal Database (MICROSOFT##SSEE) and click remove.

7. Go back to the command line and run the following commands

net stop mssql$microsoft##ssee

sc delete mssql$microsoft##ssee

8. Delete or edit the associated reg keys as noted below:

a. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server and edit the "InstalledInstances" value and remove "MICROSOFT##SSEE"

b. Remove the "MICROSOFT##SSEE" subkey under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

c. Remove the "MSSQL.2005" subkey under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

d. Rename the following folder:




At the completion of this you should be at a point where you can reinstall WSUS from scratch if you like.


Thanks Ellis!

  • Thank you for these instructions.  They worked perfectly.

  • Yeah,

    But when doing on SBS2008 (or 2003) do not remove the Microsoft##SSEE dbs.

    It is used by other items as well.

  • Got to say that this is exactly what I needed!  Been trying to re-install for 2 weeks now and your post saved my day!  Thanks for everything

  • Die Perfekte Lösung ;-)

    Stunden langes lesen in Foren und viele und komplizierte Lösungsversuchen getestet, alle ohne Erfolg.

    So einfach kann es sein.

  • SBS2008 - HELP!!!

    Did not see the ObieOne remark in time.

    We did the complete WSUS removel including MICROSOFT##SSEE on a SBS2008 server.

    How can we restore/reinstall the MICROSOFT##SSEE?


    SBS2008 backup is not running anymore!!!

  • Yes, it did it also on an SBS 2008 !

    But, in the Servermanager the WSUS Role is still checked.

    Any Idea how to remove the check on the WSUS Role manually ??

    Actually I cannot remove it through the Servermanager as this procedure did it.

    But when I cant uncheck it, I cannot check it again in order to reinstall WSUS through the Servermanager.

  • awesome, thanks, this worked great, and I was able to intall 3.0SP2.

  • Please update the guide as Microsoft no longer supports the Windows Installer Cleanup tool.

  • I agree with Frank.

    This guide is no longer a possibility due to the Windows Installer Cleanup tool not being supported.

    Please update.

  • @Frank & Addison

    I got the Windows Installer Cleanup tool from the MajorGeeks website.

    Come on man, this in an English forum, an English article with replies also in English and then you just post in German? Like everyone speaks German..then just post nothing.

  • @passing_by

    What's your problem?  I can read it.  Use Google if you can't.

  • Even after removing this, SCE 2007 Prerequisites check still shows "WSUS Version" as being the correct version but it's not in the administrative tools. SBS 2003.

  • Please note that this article is now out of date as the utility you mentioned is no longer available.  Please update your article or remove it.  Thank you.
