My computer isn't working anymore after I installed some Windows Updates
yesterday.
I got a popup saying new updates were available (Dreamscene, and some Office
stuff) so I installed them. After rebooting, I got a BSOD during the logon
screen.
Stop C000021A { Fatal System Error}
The NT initial command process system process terminated unexpectedly with a
status of 0xc0000001 (0x000000 0x000000)
I then booted to safe mode which worked fine. I tried uninstalling the
updates, but I get an error saying Windows Installer can't be used in Safe
Mode. I then tried to use a restore point but none could be found. Which is
weird, seeing Vista makes restore points before installing updates.
So now I have a system which only works in safe mode, and gives a BSOD when
started normally. The weird thing is that the BSOD doesn't happen right away.
When I see the logon/user account screen it takes about 30 secs for the BSOD
to occur.
So if I just leave it there at the logon screen I'll get a BSOD. If I
quickly type in my password and login, my account will be loaded and the BSOD
will still occur after about 30 secs but now in the desktop environment.
So it doesn't seem to be related to my account, or stuff that gets loaded at
startup.
I tried disabling all startup software using msconfig in safe mode, but it
had no effect.
I haven't installed any new hardware or drivers lately. The only thing I
installed yesterday were the Updates and the Java runtime.
So I'm looking for a solution to this problem. Either, something to make the
BSOD go away, or something to remove the updates. Is there any way I can use
the Windows Intstaller service during Safe Mode.
I tried this method (http://support.microsoft.com/default.aspx/kb/895141)
but that doesn't seem to be working for Vista
