Visual Studio 2005 (VS2005) stopped working after update

I'm using Vista Ultimate with VS2005 Pro.
I was programming when I noticed that there were updates waiting for me.
So I updated:
KB930178
KB931099
KB932330
KB905866

Now clicking on VS2005 immediately gives me the window about "VS2005 has
stopped working".

The event viewer shows this:
"Faulting application devenv.exe, version 8.0.50727.867, time stamp
0x45d2c842, faulting module unknown, version 0.0.0.0, time stamp 0x00000000,
exception code 0xc0000096, fault offset 0x01d839ec, process id 0x14e4,
application start time 0x01c77c1a097edd19."

What has happened...I need help fast!!
