Stop 0x7F during SP2 installation

[-M-]

Against better knowledge I decided to install SP2 today.

So I inserted the slipstreamed WinXP-SP2 CD and did a repair install. After text-mode installation had completed without errors, the computer restarted and should load gui-mode setup. But right after the boot screen, a STOP 0x7F bluescreen appeared with param 0x0D.

Microsoft KB says 0x7F-0x0D means a kind of application error. So I booted WinPE, loaded the registry and deactivated a couple of services and drivers. I also reinstalled Windows multiple times, no change. Booting in safe mode results in the same error. As I said, this happens when the gui-mode setup should be loaded. I also remember my attempt to install SP2 using the normal installation while Windows is running, a few months ago - same error.

Actually I want to avoid a complete reinstall, because this will reset the registry which means 80% of my programs will need to be reinstalled, also I will have to remake my hkey_classes config and so on … it'll gonna be some hours of work and so I hope someone here knows a solutions for my problem. Thanks in advance.

Bite the bullet and reinstall...even though M$ says upgrades are plausable, they very rarely are. When you add up all the downtine it's easier to do a reinstall...
