A yellow icon prompting for "IMPORTANT" update. After checking it out, went ahead with the download and installation of new updates. And that was the last time I gain access to my PC. After the installation complete it came out with the error below.

" Explorer.exe - unable to locate entry point
SHCreateThreadRef could not be located in the dynamic link library SHLWAPI.dll"

I tried repairing winXP using recorvery console to replace the shlwapi.dll and kernel32.dll I copied from my other working PC. But unsuccessful! Googled to look for solutions, so far I see quite a few complains of the same problem in other forums but no solutions are posted.

Anyone know how to resolve this problem.

Just to let you know how serious is this issue, I know as of now already 5 computers is down due to the last update. I have told all my friends and associates to disable automatic updating for the time being.
