Qfecheck.exe verifies W2K Hotfixes


Microsoft has released the commandline utility QFEcheck that gives admins the ability to track and verify
installed Windows 2000 hotfixes. Run qfecheck and the
installed hotfixes will be listed in order of Microsoft Knowledge Base article
‘Q’ number. You can run the utility remotely and create logs with hotfix
information for each computer. This can be used to create a database to manage
hotfix consistency across the enterprise. QFEcheck does
more that list the hotfixes installed. The utility will identify installed
hotfix files that are current but not considered valid and files that have been
hotfixed but are not current. QFEcheck works by
comparing the update registry information found in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates and
generating an error if it does not match the current version of the file. It
also verifies that the file information for hotfixed files is valid in the
Windows File Protection (WFP) system. WFP could have rolled back a hotfix
re-opening a vulnerability an administrator thought closed.
