I agree about beta software. I found one tidbit of info.
If your Internet Options menu isn't working, it may be
a registry key.

Go to the start menu > RUN command > type REGEDIT and press enter. Navigate through the registry keys until you get to HKEY_CURRENT_USER\Control Panel\don't load\. Look and see if inetcpl.cpl is listed. If it is, delete the entry for it and log off.

If that isn't the cause, you'll have to spend an afternoon googling for
info on the registry keys that affect the features you want to fix.
You can almost always manually fix these things with knowledge
and patience. Some of the programs that promise to fix "everything"
are too blunt. You gotta do it yourself.
