Have been working on a friend's old Compaq Presario 900 laptop. His Son infected it with viruses and it just Blue Screened on every boot. Was finally able to get into machine and Cleaned Out viruses but his User Account continues to Blue Screen on boot and the account can (NOT) be Deleted. (NO) Restore Points and (NO) HP Recovery Disc. (NEW) Admin User Accounts work fine. Blue Screen error message when attempting to Delete his old user account is a Buffer Overflow.
Question: How to Delete Old User Account without possibly destroying registry ??
Regards,
Rick P.
