Hotfixes" are the updates you installed from the Windows Update
website. Do not be tempted to remove them or you will uninstall
the actual updates.
If you wish to safely remove the "uninstall files" for the
Hotfixes (i.e. $NtUninstallQxxxxxx$ files shown in Windows Explorer)
and cleanup your Add/Remove Programs list, visit MS-MVP Doug Knox's
excellent website for instructions.
Note: Doug's program only removes the uninstall files and Hotfix entries
in the Add/Remove Programs listing. It does not remove the
actual updates.
