Do not delete/empty the "%windir%\$hf_mig$ folder"- just leave it alone
Description of the contents of Windows XP Service Pack 2 and Windows Server
2003 software update packages
http://support.microsoft.com/kb/824994
When a security update, critical update, update, update rollup, driver, or
feature pack installs GDR version files, the hotfix files are also copied to
the %windir%\$hf_mig$ folder. This supports migration to the appropriate
files if you later install a hotfix or service pack that includes earlier
versions of these files. For example, consider the following scenario:
1. You apply a security update that installs a GDR version of File.dll with
a version number of 5.2.3790.1000 and copies a hotfix version of File.dll
with a version number of 5.2.3790.1000 to the %windir%\$hf_mig$ folder.
2. You apply a hotfix that includes a hotfix version of File.dll with a
version number of 5.2.3790.0000.
In this scenario the hotfix installation in step 2 installs the hotfix
version of File.dll (version number 5.2.3790.1000) from the
%windir%\$hf_mig$ folder instead of the hotfix version of File.dll (version
number 5.2.3790.0000) from the hotfix package.''
You can - remove Old Windows Updates:-
Folders that have uninstall as part of the name (for example
$NtUninstallKB282010$ which reside in C:\windows (hidden folders) are Window
Hot Fix Update folders/files) can be safely deleted (providing you never
wish to uninstall the updates). I would recommend leaving these folders for
a period of at least a month to make sure the update is working correctly.
These updates can be deleted individually or in multiples. To find out more
about the update/s go to:
http://support.microsoft.com/?kbid=XXXXXX
NB: XXXXXX = the actual number not including the "Q" or "KB"
Once you have deleted the uninstall folders/files, then go to Control Panel,
Add/Remove Programs. Select the matching Windows Hotfix Title relating the
update folder/file you have just deleted and select remove. You will get a
Windows error. This is because you have deleted the uninstall folder/files.
Just choose OK and the entry will be deleted from the Add/Remove Programs
Listing.
