Using information from tip 4631 ยป How do I recovery a lost local user profile, I have scripted ValidProfiles.bat to display the SID and ProfileImagePath for the valid profiles that are located in your %SystemDrive%\Documents and Settings folder.

To run ValidProfiles.bat, open a CMD.EXE windows and type ValidProfiles.

NOTE: Reg.exe is built into Windows XP, Windows Server 2003, and later, or installed from the Support Tools folder of the Windows 2000 CD-ROM.

ValidProfiles.bat contains:

@echo off
setlocal ENABLEDELAYEDEXPANSION
set qry=reg QUERY "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" /s
set fnd1=FIND /I "Documents and Settings"
set fnd2=FIND /I "ProfileImagePath"
set blank=                                                                 #
set work=SID%blank%
set head1=%work:~0,60%
set head2=ProfileImagePath
@echo %head1%  %head2%
for /f "Tokens=*" %%a in ('%qry%') do (
 set line=%%a
 set work=!line:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\=!
 if "!work!" NEQ "!line!" set SID=!work!%blank%&set SID=!SID:~0,60!
 for /f "Tokens=1,2*" %%i in ('@echo %%a^|%fnd1%^|%fnd2%') do (
  @echo !SID! "%%k"
 )
)
endlocal
