My DAD's friend has windows XP on an Acer computer, and his grandkids were playing with the computer and now everytime he turns the pc his username comes up and no-one knows the password ( the grandkids are only around 7 an 8 yrs of age and they dont know how they done it) Any way is there anyway to find out the password or override it ? :-?Is there any password? May be not...Have you tried blank password?
If you have ORIGINAL XP Disk you can repair it. Have you got?They told me tried leaving it blank and pressing ok, they also tried just pressing cancel. They have tried a few different passwords. I dont know if they have the XP cd I will have to ask.try Safe Mode . Press F8 repeatedly at startup.Ask if they ever made a password reset floppy and take a look at this article. leannet.....You might try BOOTING into safe mode and  see if it will boot up from there .   If it will you can go into Control panel / USERS and click on admin ...... then you should be able to remove any passwords which might be set .
