No cannot make new profile...
Standalone PC...
Boot the PC using the UBCD and then navigate to the offline nt password and registry editing tool (in the HDD/Data Recovery section):

Using that tool you can enable the disabled Administrator account, and then when you logon to windows use the Administrator as username. Under that account you can create a new Admin account, delete the corrupt user account, and create a new standard users account.

when done, disable the Administrator account again. That you can do from within Windows by right clicking "My Computer", "Manage", "Users and Groups", "Users", right click on "Administrator", "Properties", and put a check mark on "Account is disabled".

You need a separate Admin account and a normal Local Account. The normal local account is the main account you will use when you work on the PC, and the Admin account must only be used if you are actually doing admin tasks. Actually there is practically never any need to logon directly to that account, most of the time if you do something in your regular account that requires admin rights, either UAC will show up and you can enter the admin Account's credentials, or you right click the program and select "Run as Administrator", and then the same credentials can be entered.

I can boot into safe mode ok...but it won't let me create a new account...
In user accounts the link...Manage Another Account seems to be locked...

I made a UBCD but I get no graphic GUI to work from...only DOS controls...
I can get into HDD Data Recovery section...but cannot any accounts let alone turn on the Administrator account...

Tried another linux type tool...NT Password and Registery editor...found the admin account
but cannot change anything...

Searching for another method...

it looks like your disk has problems
since you have the UBCD -  
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

to be sure, i always run a ram test before
That's what the UBCD is, a collection of very useful tools that don't run under Windows, some are based on DOS, others on their own environment. You don't need a GUI for it. There is a menu after you have booted it which helps you find and start the tool you need to run. The One I mentioned to enable the Administrator account is linux based. Just follow it's help system when it has loaded and you should be able to enable the account called Administrator.

I'm getting it...!!!
Got booted into safemode...At cmd line I used net use to create a new acct and move it
into admin group...
I rebooted into Win and logged into the newly created account...
I should be able to fix the corrupt profile in the normal way now...

Running the HD diag tool now...

I've used UBCD a couple times over the years...but I'm not a very good command line guy...
And the UBCD just kinda "overloads" my personal RAM...:>)....

I have another similiar to UBCD, lots of tools and it had a GUI very similar to XP...And I thought that was UBCD...but I confused with something else...

Thanks for all the help...I'll close this after I've got the profile fixed just in case I need to ask another question...
That was probably the UBCD4Windows, which you build using an XP installation CD. It is more complicated to build, and you need an XP CD and license (not OEM), and it doesn't include many of the tools you need for doing proper hardware diagnostics which the normal UBCD has.

Or then it was a Linux LiveCD or DVD of which there are many around.

Why not just create new account now delete the other account
Steve MutchlerIT TechAuthor Commented:
If I recall the procedure correctly...I'll double check...
You rename the old profile...
Create the new profile...
Move everything from the old to new profile...
Then edit the registry..,.and here I have to look that up...
But it's not quite like XP....
i don't see how you can create a new profile - if you can't log on ?

for most programs on the UBCD - you don't need command line; just selct options with your mouse, or arrow keys
that's it

Nobus....booting up into "normal" windowns I cannot log on with the only account available...
When I went into safe went directly to the desktop...did not ask for a login...

I was able to open the CMD prompt and use the net use commands to create a new
account and then move it to the admin group...

Rebooted and both accounts showed up on the login screen, I logged in with the
new account...then did the regedit S-1-5 changed the user key which ended in .bak...

Reboot and was able to log in with the normal account no problem...\
Everything was working perfectly...did a chkdsk, ran virus scans everything seems fine...
tx for feedback - did not know that one yet..
