Critical System Failure After Windows Updates

I've had a beautiful XP system going now for about 4-5 weeks. Smooth as silk and fast. Fully protected; love the OS.

I just completed about eight Security Updates from the update site. Seemed to download flawlessly, verified, and then installed themselves. I was told to reboot, whereupon I no longer can boot up normally OR EVEN IN SAFE MODE. It just keeps restarting over and over.

When I "Disable automatic restart after system failure", I get a blue screen with the following error:

"Stop: Bad Image Checksum
The image urlmon.dll is corrupt. The header checksum does not match the computed checksum."

Do I have a way out of this crap?

This agony from Windows XP updating itself!

I'm writing this to you guys from my 98SE machine which has NEVER failed me in five years.

Have you tried a "Repair" with the XP CD?

I'm not sure what to go about. The MBR is okay; the boot files on "C" are okay. I don't know how to handle this urlmon thing. Which repair would I do?

Well looks like you will have to reinstall. You can either re-format the drive and start over or just reinstall the OS over your current install. A re-format is probably the best option in my opinion.

Will reinstalling over the existing save my Outlook Express files?

While LMAO I forgot to mention that in the order to save your files you have to install XP into different folder ("ILoveXP_2" will do) and then copy your OE into your new install folder (but copy it after you reestablish accounts first to have it foolly functional).

Anyway, in the future (I mean take it as a free lesson) have your OE files in the separate drive (partition) from your OS so next time (based on your experience approximately 4 to 5 weex) your lovely XP goes tits up you still have your mail intact.

I took a shot to try and fix this problem.

I copied urlmon.dll from a friends' machine onto a floppy, and came home and booted up with my XP cd until I saw the option for Repair. This gives me a C:\Windows prompt. I change directory into System32 and copy the dll from the floppy into the system32 folder.

I rebooted (removing all disks), and voila, I went right into my desktop with everything okay.

Nothing ventured, nothing gained!

Happy ending is a good thing, but a good thing with a happy ending is much better ( if you know what I mean ;o)

PS: I mean you have a good brain to fix a thing, which is a good thing, hehehe..

PSS: meanwhile, did you make your OE folder on a different partition to have it "safe" for next time when XP decides to looze a system file, hehehe?

First thing I did was transfer my "Storefolder" to my second hard drive. Good advice!

Go into safe mode and do a system restore.
