WinXP PRO Safemode Auto Reboot Loop

[Reverend]

Only XP update KB898461. Surely that.......OMG. I wonder.

I wouldn't think its that causing the problem. That is just an update that installs a permanent copy of the Package Installer.

Have you tried system restore ?? Select a point prior to the windows updates.

Alternatively uninstall the updates one by one via add/remove
