After machine assembled (see specs if relevant below) Installed XP Pro, then SP2, no problems apparent after each discrete install (Encountered same problem with updates after first tried "integrated" or "slipstreamed" install so then went to step by step install method to make sure problem was not with slipstreamed disk). Issues happened after everything was working well. So, being prudent, performed windows update and found there were approx 36 security and other updates post SP2 updates, e.g. .NET framework, etc.
After install of updates, on reboot, I get the BSOD and STOP error 0xC000021A. Initially, the machine will go into a loop of rebooting, but hitting F5 and selecting don't reboot on error stops this, leaving the error to be read.
Believing the problem to be one of the Hotfixes/updates, I want to uninstall or disable the hotfixes in question rather than install Windows again.
In order to do this, I think I have to use the Recovery Console. I know how to get to the console, select the OS folder and log in as the administrator - the problem is how to properly remove the updates.
I want to use the correct Recovery Console command, whether it be DISABLE or DELETE or something else.
If someone has successfully removed a troublesome update before, I would appreciate the advice on both the correct command to utilize and also, the particular syntax to use - e.g. Disable $ntuninstallKB896423 (space - or enter or suffix?)
Any other words of advice would be appreciated.
I find it interesting that service pack 2 did not cause the problem as I have read is the case with some users, but one of the updates. Thoughts on this are also appreciated, otherwise, if advice on using Recovery Console given gets me going, I'll have to try installing the updates one at a time to find the culprit.
For what it may be worth, machine is a new homebuilt machine w/ Asus A8n-Sli Premium MB (Bios set to single card for Nvidia Quadro 540, AMD 4400+ dual core cpu (bios not updated to most recent 1011, but at 1008 allows even XP to see "2" processors - AMD driver then installed with no problems), 2GB SDRAM, 2 250GB SATA drives, NEC 3500a DVD burner, no sound card currently installed and onboard sound disabled - will be using A) M-audio 1814 firewire - I did install a PCI (texas instrument chipset) 3 port firewire card (Motherboard PCI slot 2) that caused no problems on install of XP or SP2. Device manager showed no issues on install or post SP2.
