This is a way round it, using a Registry Fix. * I screwed mine up, but if you read about my mistakes and remeber then before you start this. You should be able to fix your missing user names and pics from your welcome screen.
Maian thing is, I have my program back that was installed on the desk top - not in the program files.
Also of course - some of my recent work - I always back-up what I am working on, to an external hard drive.
After three days of searching, and being online for 40 minutes with Microsoft Answerdesk chat http://answerdesk.microsoftstore.com/ just this morning, 2014-10-10 - the agent did not know of any other way to get into windows XP except by using either safe mode (which does not work for most people like me experiencing this problem), or by loging in as a power user (CTRL+ALT+DEL TWICE).
I also discovered that if you have no-passwords entered in your admin or user accounts like I did; Then you cannot reset passwords or get passwords pulled from your PC HD by certain software methods. (Hook up you HD to another PC as an external; type of processes).
eg- search for this article 'Three free tools that reveal your PC's deepest details (including product keys)'
Also you can sort of fix your Registry files, as I tried to do using.

Because my c:\ drive is NTFS
At the point where you are told to find the 'SNAPSHOT' folder.... Be careful..
A problem I encountered was - I used the most recent file from my System Volume Information folder - that had todays date 10-10-2014 - I had another file dated a month ago in September and I should have used that. Or at least taken a copy of both files, and put them into the TEMP folder - they are supposed to be safe there 'temporarilly' of course. MY ADVICE - copy that whole folder into the TEMP folder and then rename it to something stupid so that you can remember it, but so that windows software will not pick it up by mistake,, Then you can come back to that folder and work on another system restore point if the first does not work.
Because I did not do this, the system overwrote the older September file. I did find the folder in another remp recycle bin (yes, there are more than one), I could not see the information inside the folder though, but I remember wat files were in there..
I can now see my program files and the main software I was most concerned about losing - when I am now successfully running in SAFE MODE- in my 'Andy' user account - as a folder. But my previous profiles are still not showing on a welcome screen - in fact there is no welcome screen yet - I think it is just turned off.
Another problem to watch out for - is that they tell you in the instructions, to copy to the 'tmp' folder and I did not have one - I do have a c:\windows\temp folder though - when I was working in cmd mode - and error message said something like destination folder does not exist..
TIPS: Make sure you know what your c:\windows\temp folder is called exactly.
Also make sure you type very accurately, even a mistake in a space can send this all down the toilet.
Like in
https://support.microsoft.com/kb/309531
Type the following line, and then press ENTER:
cacls "driveletter:\System Volume Information" /E /G username:F
There is a no space beween the speech mark and driveletter "driveletter - and ther is a space between /E /G yet is threw up an error message. - With trial and error, I took out the space between /E/G and it accepted the instruction.
So my line was "c:\System Volume Information" /E/G Administrator:F
BEFORE you do this - it will just put your PC quite near the state where it used to be. - Make sure you have your activation keys - your PC will reset to the new regitry state, (sometimes like mine did - you will have a different screen resolution - like it was in 600 x 800).
By the time you finish - you will get you screen res back, if you do the reg fix correctly. However, you might also want to change the screen res in order to work with it easier. It will still chang back to what you had when you finish the registry fix.. ;-)
Activation Key needed... make sure you have yours before you do this..
The message states - "This copy of Windows must be activated with Microsoft before you can log on."
Then my wiresell mouse and keyboard did not work any longer - I have to plug in an old wired keyboard and mouse to control the PC.. Annoyingly - I left the wireless devices connected and had to restart to make the system pick up the new plugged in mouse and keyboard, but the wireless ones then started working.. (Just watch for that).
Windows was unable to activate online - even though I had my internet and networking all working from before the issue.. That's not a problem I will do it later when I have the system running as normal.
ANDY - Sorry this was long and not perfect - but if one of the more apt PC fixers can sort this mess out and rewrite it, they are welcome to do that,, I just wrote about my problems fixing my missing usernames and pictures - gone from my welcome screen for no reason - when I switched on one morning three days ago.. Its been a 72 hour slog..
Thansk for all your help here everyone.. I'll drop by later...
Some other things I did try before this Registry Fix.
Previously...
I tried FIXBOOT within my install disk system 'R'epair mode. That did not work.
I DID NOT do FIXMBR - as this will destroy something - (I ignored this advice not to use this once before and paid the price for my lunacy).
The only advice from MS Answerdesk was to re-install from my XP home install disk.
They were wrong about that.. So who knows..
My startup option keys on this ASUS Mobo are
F2 - Bios
F8 - (Start up options - like safe mode) =Windows Advanced Options Menu.
F10 - Boot Options to select which drive or DVD / CD rom to boot from (to run the install dist etc).
Pressing SPACE BAR - during startup -
SpaceBar - brings me to
HARDWARE PROFILE / CONFIGURATION RECOVERY MENU
(It says (white text on black screen) this is not the same as F2, F8 or F10).
The page says:-
This menu allows you to select a hardware profile to be used when Windows is started.
If your system is not starting correctly, then you may switch to a previous system configuration, which may overcome startup problems.
IMPORTANT: System configuratuion changes made since the last successful startup will be discarded.
Profile 1
Use the up and down arrow keys to move the highlight to the selection you want. Then press ENTER.
To switch to the Last Known Good configuration, press 'L'.
To Exit this menu and restart you computer, press F3.
-----------
I then tried LKG - Last Known Good (first - as you do). But I think this is the same as doing LKG elsewhere. The instructions change to give you the option to go back to the 'Default' cnfig if you press 'D'. -(To do LKG after pressing 'L' next press enter. LKG didn't work for me. Still same state as at 1), above.
------------
Since there is only one profile (Profile 1), there is nothing to select and this means that the PC 'IS using' Profile 1 (where the problem is). So, that did not work for me either.
Andy.
My advice - always back up your registry files and other programs separately. and in addition, use a backup service. Although I used to use AVG - but that service has gone now I think. The problem with that expensive solution, is that it did not work as promised. The tech says recover your crashed, damaged PC from any state. That was not true, my first problem could not even be fixed by a total re-install and then run the backup to replace the files. I think that was the process I did about two years ago now.. Asked for my money back, didn't get it.
