Just an FYI as having to do a Reset is not an ideal solution, nor one I would ever recommend as it's a bad feature altogether, analogous to treating a minor scratch with amputation.
There are several free DOS utilities out there that can easily remove or change a forgotten Windows password. HBCD 15.2 [Hiren's BootCD] contains several DOS programs that can do so
- Boot to HBCD -> DOS Programs -> #3: Password & Registry Tools -> #1 Offline NT Password Changer.
- Simply follow the prompts of what's being asked. ensuring one fully reads the output & what's being asked.
I would link to the HBCD site, however it includes a pirated copy of Windows XP and therefore would likely violate forum rules. If for anything else, it contains an excellent set of DOS freeware that comes in quite handy for troubleshooting and fixing issues.
