How to: Manually Uninstall a Windows Home Server Add-in

One of the great things about Windows Home Server is the community development scene that has sprung up around the platform, which has led to a huge range of add-ins being made available for free. You can check out what’s available and see which ones are the most popular at Home Server plus.

Most of these add-ins behave well, but from time to time, one or two may present a problem – these are community development projects after all. If you find that you’re unable to uninstall a problematic add-in, the following walkthrough, prepared by WGS Wiki Editor Etoa, with help from Sam Wood, will help you through.

Remember, this is an advanced procedure, so go carefully and follow the instructions to the letter, particularly with regard to editing the registry.

What you will need

The first thing to do, if you haven’t already, is to reboot your server. Sometimes that will clear the problem. If not, then do the following:

  1. Make a note of the EXACT name of the add-in that cannot be installed (“WHS Disk Management” for example).
  2. Gain access to to your Windows Home Server either through a Remote Desktop connection, the Advanced Administrative Console add-in or monitor and keyboard if you have one attached.If you loaded Advanced Admin Console, on the far right side of the toolbar is a down arrow. Click that and a menu should appear. Select Registry Editor. If you are using a Remote Desktop Connection or direct access, click the start button, select RUN and then type “regedit”.
  3. In Regedit navigate to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Home Server\RegisteredAdditions\

  4. Locate the subfolder that references the name of the problem add-in (“WHS Disk Management” for example) and delete it.


  5. Exit regedit.
  6. Open and then close the WHS console from within the remote desktop session to free up any in-use files.
  7. Using “My Computer” navigate to C:\Program Files\Windows Home Server\
  8. If present, delete the relevant add-in console tab file (“HomeServerConsoleTab.DiskMgt.dll” in this example. The tab name will vary depending on the add-in being deleted).


  9. Close My Computer.

  1. Thanks for this, I had been having a problem with a stubborn add-in and just couldn't get it out, this did it! The ASoft ap only gets rid of duplicated add-in and if the ap changes anything, it doesn't do that great a job with that. This works much better. Appreciate the help.
