Failed to create startup registy entry to run batch command

I am trying to optimize W7 UI for a laptop with a wide screen by putting the taskbar on the left and making it thin. I managed this a couple of ways the most successfully by restarting UxSms with Task Scheduler and a batch file. This source is what gave me the idea that I could run the batch with Regedit.

The actual question I would like to answer is why the .reg I made merged without error, but didn't create a key that I could find or seem to run anything when the previously mentioned "This source" seems to suggest that it should work. Obviously I made a mistake, but would really like to understand it.

Name of file: ThinTask.reg

    REGEDIT4

    ; @ECHO OFF
    ; CLS
    ; REGEDIT.EXE /S "%~f0"
    ; net stop "UxSms"
    ; net start "UxSms"
    ; EXIT

    [HKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionRun] "ThinTask"="Succeeded"

The batch I want to run is really just:

    net stop "UxSms"
    net start "UxSms"

Any ideas on where I went wrong? Thank you for your time any comments, suggestions, or resources are most welcome.
