Welcome, annoyed friends.
Here is how to remove those space-hogging, good-for-nothing
Windoze Update (also called "hotfix") backup files from your
hard disk and from the Add/Remove Programs Control Panel,
and still have Windoze Update recognize your updated system files.
I have tested these steps on my Windoze 2000/SP4 installation and I
guess the same will work on WindozeXP but YMMV.
You must be familiar with the use of the Registry Editor to perform these
steps. Don't come crying to me if you accidentally deleted the whole HKLM
tree! If in doubt, don't do it... or get the shareware automatic remover
XP_Remove_Hotfix_Backup from Doug Knox.
- Instead of deleting files, move them to a temp directory;
- Export the registry branch before deleting its leaves;
- Find out which hotfix backup you wish to remove; jog down its "KB" or
- Log in as administrator
- Start Windoze Exploder, select Tools - Folder Options - View - "Show
hidden files and folders"
- Start Registry Editor; if you don't know how then you should not attempt
Altering your system
- With Windoze Exploder, go to your Windoze system folder,
e.g. "C:\Windows" or "C:\WinNT"
- Move/delete the $NtUninstall<whatever-KB/Q>$ folder,
e.g. "$NtUninstallKB820888$" for the KB820888 Windoze 2000 NTFS hotfix
- Move/delete the <whatever-KB/Q>.log file, e.g. KB820888.log
- With Registry Editor, go to
and delete the UninstallCommand value, e.g.
- Note that there may be no or more than one sub-component in the registry
branch, so you may wish to search for the "UninstallCommand" value instead of
exploring the branches.
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall and remove the
<whatever-KB/Q> key, and all the values contained within,
e.g. remove this key
- Optionally remove the key and all the values cotained in
- I could not find out the function or the importance of the ARPCache, so
perhaps it is best left untouched. However, a no-backup install of a hotfix
does not create this key in the ARPCache.
Leave these keys alone
(Windoze Updates look for these), and
(Some kind of cache for Windows Exploder, should be harmless).
Go to the Windoze Update site
and let it do a scan. It should not find anything amiss. Job done.
In future you may wish to download the hotfixes and install them using
the "/n" (or "/nobackup") switch, but updating this way means you will lose
your insurance against Microsloth stuff-ups.
