My OS started requiring a username/password

[Jon Lachelt]

I'm running XP home edition, SP2 .

Yesterday, after a windows update was installed, and a reboot... our
computer started prompting for a username/password.

It has never been configured to require a logon before.

Nothing I enter will let me in.

Any ideas for how to get in would be appreciated. My final resort will be
to fall back to Windows Recovery.

When booting your computer, press F8 before the Windows splash screen
and then select "Last known good configuration that worked". This runs
the system restore program and will return your system back to how it
was prior to installing the last update. Hopefuly this will sort your
problem!

There is a program called winternals ERD Commander which boots from CD and
allows you to reset the system password.
Might be difficult to get a hold of however as microsoft has bought the
company out (presumably because they were making their software too
vulnerable)

This seems to be caused by one of the .Net Framework installation.
You will see that a separate new user of ASP.NET may have gotten
created on your PC. One quick way to fix this is to get TweakUI
Powertoys for XP. Look under "Logon" and uncheck the user accounts
that you do not wish to show up on the Welcome "logon" screen.
