I've written a screen saver, and I'm trying to make it the current screen with a batch file. I can do all of the file stuff, but I'm having trouble updating the registry. BTW: I am in admin mode. My code so far:

(Toggle Plain Text)

cls

del MBScrnSvr.scr
ren MBScrnSvr.exe MBScrnSvr.scr

IF NOT EXIST c:\Windows\system32\MBScrnSvr.scr GOTO INSTALL_SCRNSVR_END

del c:\Windows\system32\MBScrnSvr.scr
:INSTALL_SCRNSVR_END

copy MBScrnSvr.scr c:\Windows\system32\

rem  key:         HKEY_CURRENT_USER\Control Panel\Desktop\SCRNSAVE.EXE
rem  Key value: C:\WINDOWS\System32\MBSCRN~1.SCR

HKEY_CURRENT_USER\Control Panel\Desktop "SCRNSAVE.EXE" = -

HKEY_CURRENT_USER\Control Panel\Desktop "SCRNSAVE.EXE" = -s C:\WINDOWS\System32\MBSCRN~1.SCR

Thanks.

Yes there is a way to update the registry from a batch file. However, it will require a second file (import.reg). The batch file code will look something like this:

(Toggle Plain Text)

cls

REGEDIT.EXE /S C:\Import.reg

cls

The import file will be created by exporting the hive containing the key to be changed. Remove all text with the exception of the registry editor title line, the path, and key with key value to be updated.
Ex:

(Toggle Plain Text)

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]
"SCRNSAVE.EXE"="C:\\WINDOWS\\System32\\MBSCRN~1.SCR"
