I am running XP-PRO,512MB,30G-HD with 800mHZ.4yrs of nearly perfect operation.I download a powerboost software(PC Mighty Max) and all was well. This software had no uninstall and add remove could not remove it. I used Regcleaner to removed the software and upon reboot i got killed. Error message is "Windows Product Activation... A problem is preventing windows from accurately checking the license for this computer. Error code:0x80070002"
I restart in "Safemode" and select restore but restore window opens and do nothing. Norton does the same and AVG7.0 has completely disappear.
What is my next move folks
