I am trying to fetch all registry entries under
HKEY_Local_Machine\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and Delete if REG_EXPAND_SZ key contains value C:\Users\sas-
Ideal Steps Script should do :
1) Get all Registry entries for users Using :
reg query "HKEY_Local_Machine\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList"
>> xyz.txt
2)If users name is sas-### (which we can get in "REG_EXPAND_SZ") then delete this entry :
for /f "skip=10 tokens=* " %%a in (xyz.txt) do (
for /f "eol=; skip=2 tokens=4 delims=\t" %k in ('reg query "%%a" /t REG_EXPAND_SZ') do (
if %k == "sas-" (reg delete "%%a")
)
)

Answer 1

Try this:
for /f "tokens=*" %%a in ('
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList"') do (
for /f "tokens=*" %%b in ('
reg query "%%a" /v "ProfileImagePath" 2^>nul ^| find "sas-"') do
rem reg delete "%%a"
echo "%%a" >>C:\names.txt
)
I've based this on you querying the ProfileImagePath value, and deleting any of the keys that contain sas-* in the value. I've also put in a few line breaks you will have to remove (just for easy viewing on SO).
Please test this first (I've echo'd them to a text file at the moment), if you are happy with it then remove rem from the reg delete line.

Answer 2

You should be able to do it from a single For loop; however, I do not particularly like the idea of removing profiles using this method.
#Echo Off
For /F "Tokens=1-2*" %%A In ('Reg Query^
"HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" /S^
/F ProfileImagePath /V 2^>Nul') Do (
If Not "%%~A%%B"=="ProfileImagePathREG_EXPAND_SZ" (
Set "_C=Reg Delete "%%A%%B"") Else (Set "_P=%%~C"
SetLocal EnableDelayedExpansion
If Not "!_P:C:\Users\sas-=!"=="!_P!" Echo=!_C!
EndLocal))

If you're happy with the console output then remove Echo= from line 8 and delete line 10.
