Fix Windows BSOD after Feb. 9th, 2010 Updates. (stops at mup.sys)

After Feb 9th updates, an XP machine may BSOD (blue screen of death) on restart.  If you try to start in Safe Mode, the machine quits at mup.sys.
To repair... Follow these steps:
  1. Boot from your Windows XP CD or DVD and start the recovery console (instructions are here : Microsoft) Once you are in the Repair Screen..
  2. Type this command: CHDIR $NtUninstallKB978262$/spuninst
  3. Type this command: BATCH spuninst.txt
  4. Type this command: systemroot 
  5. Repeat steps 2 - 4 for each of the following updates
    • KB978262
    • KB971468
    • KB978037
    • KB975713
    • KB978251
    • KB978706
    • KB977165
    • KB975560
    • KB977914
  6. When complete, type this command: exit 
  7. Restart the machine.. should start fine. 
  8. If auto updates are enabled... diable them and 'download only'... so you can disable those updates. 
  9. You 'could' do the updates one by one to determine which one caused the BSOD. On my client's machine... it was KB977165 
  10. Remember this : Why this worked!
