I tried to store the current ConfigMgr patch state during ConfigMgr Backup automatically to make sure i can restore the exaclty configuration after a Server Crash.
Unfortunately the command wmic qfe list does only list installed Windows Updates.
If you want to to the same you can use the following command
For a 64 Bit Windows Server
reg query "HKLM\SOFTWARE\Wow6432Node\Microsoft\Updates\System Center Configuration Manager 2007\SP2" /s > ConfigMgrPatchState.txt
For a 32 Bit Windows Server
reg query "HKLM\SOFTWARE\Microsoft\Updates\System Center Configuration Manager 2007\SP2" /s > ConfigMgrPatchState.txt
You can automatically execute the command after the Backup by using the AfterBackup.bat
