Critical Windows patch may wreak PC havoc


Here's what I found:


  • Desktop PC 1 running Windows XP Home Edition. No problem.
  • Desktop PC 2 running Windows XP Home Edition: No major problems on reboot. However, Microsoft Office 2003 patches would not install using the web based update process. I ended up downloading the full installation file and then executing it from the hard disk to get it run.
  • Desktop PC 3 running Windows XP Home Edition. No major problems on reboot. However, Microsoft Office XP Professional patches would not install using the web based update process. I ended up downloading the full installation file and then executing it from the hard disk to get it run.
  • Notebook PC 1 running Windows XP Professional Edition. No problems.
  • Notebook PC 2 running Windows XP Professional Edition. My user profile settings disappeared and I could not login after the first reboot. I was able to login after the second reboot but my user profile settings had disappeared. The user settings reappeared after the third reboot.
  • Notebook PC 3 running Windows XP Home Edition. The notebook stalled in the middle of the boot process and reported This application or DLL C:\Windows\System32\umpnpmgr.dll is not a valid Windows image. I tried using a Safe Mode reboot and also restoring using . I ended up reformatting and reinstalling Windows XP on this notebook (data was backed up, so no hair pulling took place :-). I applied all the patches again to this rebuilt PC (upgraded to XP Professional Edition since I had to rebuild from scratch).


As you can see, I had a real mixed bag of experiences during this Patch Tuesday period.
I hope you had a better more consistent experience.
