About qfecheck.exe and hfslip'ed installs.

[Martin H]

On the hfslip homepage under 'Guidelines > Other important notes', then it states that hfslip support the qfecheck hotfix. That is correct, but however, just keep in mind that you cannot use qfecheck to verify the integrity of updates slipstreamed by hfslip...

Qfecheck.exe gets the list of installed updates by checking under this reg-key: 'HKLM\SOFTWARE\Microsoft\Updates', and then verifies the integrity of the updates, by checking the file version information stored for each update under that key, against the file versions of the installed binaries. However, hfslip doesn't add any file version information to these keys, as that's not done by the update INF itself which hfslip runs at T-13, but by the actual update installer itself, so qfecheck.exe will think that no files are updated by the updates and hence, will just report no problems for each update referenced under that key(some updates just add new reg-keys and don't update any files)...

For verifying slipstreamed updates on a hfslip'ed install, then you can instead use e.g. HfNetChk(note it dosen't report missing updates for DirectX or OE), MBSA or WU/MU.
