The Key in question is a messenger installer key as i am working on a messenger removal addon for our logon scripts to stop users messin about on it hehe here is the key:

HKEY_CLASSES_ROOT\Installer\Products\C838BEBA7A1AD5C47B1EB834410B5034

If i can eva get rid of it via the logon script since i`ve also looked at regedit and regedt32`s command line switches and can`t find one as such yet to delete keys, guess i`m gonna hav to search for a third-party app that does hehe Oh joy [Razz]
