This should be straightforward.  On 8/18 Microsoft pushed out WinXP security updates which I installed automatically.  Since then at start up there is a series of 8 error messages that Windows can't find my Documents folder, Registry, 'And', Settings/Adm/Applications, ***Registry, Data\Admin\manager.exe, ***Registry.

If I immediately click through all of these the system boots up fine.  If I start the system and walk away without immediately clicking through these 8 messages the system locks up and I have to reboot.   This has been the only change to my system so I'm assuming it's related to the latest security update.  I have not attemepted a restore point.

Thanks.
