JSI Tip 3333. Microsoft has released a tool to verify the installation of Windows 2000 hotfixes.

Qfecheck.exe enumerates all the hotfixes on your system, and determines wether they are properly installed.

To determine which hotfixes are currently installed, the tool inspects the entries at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates

It uses information that is stored for each hotfix to insure that the binary files have not been over-written.

It also identifies hotfixes that are not considered valid by the installed catalogs. For each file that was installed by a hotfix, Qfecheck determines if information that WFP would use matches the installed catalog. If Qfecheck determines that there is a mismatch, see Q281767 - Updated Sp2.cat Available to Resolve Versioning Issues with Post Service Pack 1 Hotfixes.

The Qfecheck.exe CMD Syntax is:

QFECHECK \[/l\[:location\] /v /q /?\] 

   /l   Log output to .log in the current folder
        location. Use the specified location to store the 
        log file.
   /v   Verbose output
   /q   Quiet mode
   /?   This help
