I want to disable the preview pane in Outlook. Here is the script that I'm tring to use:

WriteValue ("HKEY_CLASSES_ROOT\CLSID\00020D75-000-0000-C000-000000000046}\Shell\Open\Command", "(Default)", "C:\PROGRA~1\MICROS~2\Office10\OUTLOOK.EXE /nopreview", "REG_SZ")

After the sript runs the changes aren't made.

Thanks
