List installed ConfigMgr Hotfixes automatically

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

Task Sequence Environment not available

Problem:
Your deploying a Script which shell use Task Sequence Variables with SCCM.
There seems to be a problem when creating the object for the Task Sequence Environment CreateObject("Microsoft.SMS.TSEnvironment").
You may also get the following error: Error 429 - ActiveX component can't create object.

Solution:
Make sure that your really running the script within a Task Sequence. Also check that you have created a Task Sequence Advertisement (Advertise Task Sequence).
