Using REG QUERY to check for a certain string

[Callahan]

Can this be done? I want to run a batch file that will check if the correct entry is set in a reg key and if not change it to the correct entry. This is what I have so far:

REG QUERY "HKEY_USERS\.DEFAULT\Control Panel\Desktop" /v Wallpaper >NUL && set WALLPAPER=Correct

IF %WALLPAPER%==Correct (GOTO :INSTALL_POWEROFF) ELSE (GOTO :SET_DEFAULT_LOGON_WALLPAPER)

:SET_DEFAULT_LOGON_WALLPAPER
REG ADD "HKU\.DEFAULT\Control Panel\Desktop" /v Wallpaper /t reg_sz /d C:\WINDOWS\Web\Wallpaper\ffback.bmp /f

It works as there is always something set in the Wallpaper entry but this can be any setting, usually the default OEM wallpaper. What I want to do is query the registry for a specific path such as: C:\WINDOWS\Web\Wallpaper\ffback.bmp.

Can this be done?

Thanks for any suggestions you can give.

Why not just force setting it anyway?

I am currently doing that but as there are at least 3 batch files that run during logon to set up various things I wanted to make this one as streamlined as possible so that it executes quickly. For one thing it prevents the user from killing the batch window if it only appears very briefly.
