Hi,

I did try to recover from corrupted registry but didn't find system registry
in the
"c:\windows\repair\system" and now I can't log in neither on windows or in
the recovery console anymore. Because I have to type a password that I don't
have because I didn't assign any password to the administator account.

Does windows has a standard password for the administrator account?

Thanks in advance,
Eduardo.
 
Eduardo, if you didnt assign a password for the Admin Account then you
should not need one for the Recovery Console.
If you use Windows Restore and you can connect your drive to another
computer I can give you a fix for your problem.
Otherwise you can try a Repair Install of XP. You need the XP CD for
this. For more info check here

Hi Rich,

it's wierd... because before trying to recover from corrupted registry I did
log onto windows with a empty password but now I can't.
Now I'm stuck at the log on menu of the recovery console because the system
does not accept any password.
 
Eduardo, ignore the request for password and just type in the number of
your drive and hit Enter. What you want to achieve
is to replace the five registry files with the original ones. The
registry files are located in C:\windows\system32\config folder.
The originals are in C:\windows\repair folder.
At the Recovery Console command prompt, type the following lines,
pressing ENTER after you type each line:
md tmp
copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

delete c:\windows\system32\config\system
delete c:\windows\system32\config\software
delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\default

copy c:\windows\repair\system c:\windows\system32\config\system
copy c:\windows\repair\software c:\windows\system32\config\software
copy c:\windows\repair\sam c:\windows\system32\config\sam
copy c:\windows\repair\security c:\windows\system32\config\security
copy c:\windows\repair\default c:\windows\system32\config\default

6. Type exit to quit Recovery Console. Your computer will restart.
Note This procedure assumes that Windows XP is installed to the C:\Windows
folder. Make sure to change C:\Windows to the appropriate windows_folder if
it is a different location.

If you can connect your drive to a working computer then here is my
method which uses the five registry files as System Restore would use them.
It gives you a working registry which is almost identical to the one you are
replacing minus the corruption.


First, go to Windows Explorer>Tools>Folder Options>View. Check " Show
hidden files and folders". Uncheck " Hide protected

Operating System files". Then go to C:\System Volume
Information\restore\RP\Snapshot Folder. Copy the first five files after

the Repository Folder. Then go to C:\Windows\System32\Config Folder. When
Config folder is open create a new folder. Then

move SYSTEM, SOFTWARE, SAM, DEFAULT and SECURITY files in to new folder.
Now paste the five files you copied from

Snapshot Folder. Rename each file by removing REGISTRY_MACHINE_ from each
file. You should now have a recent working

Registry.



Note: Usually you will see a few if not many RP folders. Choose the Fifth
most recent. So if your most recent RP Folder is

numbered RP20 then choose RP15 to select the registry files.
 
Hi Rich,

I did try recovery console but when trying to
"copy c:\windows\repair\system c:\windows\system32\config\system"
the file couldn't be found so what I did was
"copy c:\windows\tmp\system.bak c:\windows\system32\config\system"

I think that I made a huge mistake HERE!

Now after I select the number of the drive I have to enter a password for
the adminstrator. And the system doesn't accept any password neither empty.

I tried to repair install but didn't work, when entering the log in screen I
will get lsass.exe error report: password incorect... and this without
entering any password.

About connecting the drive to a working computer, I don't think I can
because it's my laptop. I don't know if I can connect the drive of my laptop
to computer and how to do that.

Have you tried just pressing Return without entering a password?
