Windows XP Home machine login problem

Yes.

Did you check for the existence of backup registry
files in c:\windows\repair?

I renamed the SAM file and rebooted the machine while windows was starting
it gave an error with the window title as "lsass.exe" a device has been
disconnected causing the user accounts.........click OK to reboot go into
safe mode and repair it.

Then i copied the SAM,SECURITY, SYSTEM, DEFAULT, SOFTWARE files from the
c:\windows\repair to pasted them in c:\windows\system32\config. After this
rebooted the machine still no change the machine boots but no usernames are
being displayed.

I thought your biggest problem was no so much the
lack of displayed user names but your inability to log
on after pressing Ctrl+Alt+Del twice?

You should also check the date of the registry files you
retrieved from the Repair folder and compare it with
the date when your problems started.

Greetings,

If the admin pass is lost or forgotten then Active@ Password Changer
utility can be used to reset it. That is a really mighty tool, it never
failed me before and worked simply great. I suppose you definately try
it out.

This may be overly simplistic, but the pc said --"loading your settings" and
then "saving your settings" -- then eventually went back to the Welcome
screen. Do you suppose it has deleted the place it would normally save the
setting and doesn't know how to recreate it?

I have been just going through the same problem as you (no login
buttons....) and have come up with a solution that fixed my HP Laptop.
Using the Bart PE cd referenced in your earlier posts, I was able to
boot the Laptop and work on the file system.

Using the assumption that the SAM file was corrupted, I replaced the 5
registry files in the C:\windows\system32\config directory with a set of
files from the system volume information (system recovery folder)
snapshot folder (picking a date from about 10 days ago. The basic file
replacement procedures is listed in the
http://support.microsoft.com/?kbid=307545 document. The only shortcut
that I used was to not bother to copy from the C:\windows\repair folder,
and just go right to the system restore images of the 5 files.

By the way, the old sam (bad) file was about 250k, and the new one from
the system restore folder was about 24k.

A large part of the problem is that this bad update ends up corruptin
the hive files and also identifying several windows files as suspect
and therefore disables tehm on the startup scan. Since th
quarantined files are needed for bootup the system freezes at th
Welcome screen but does not give any user options, and simply wait
for input that it will never allow itself to receive. CTRL + ALT
DEL will not work to unlock things.

Again, I strongly recommend running a system restore from the recover
console to regain access to your computer and then to run an update o
your security software
