Hello Shone89 and Welcome to Seven Forums,
Why do you want or need these options removed?
Can't you just ignore them?
It's not unusual for Windows programs to disable options that are not applicable "at the moment".
I think it's better for stability and reliability to not try and tweak Win 7 and make changes to do things it is not designed to do.
Maybe there is some registry tweak or 3rd party program that will do what you want, but is it worth it?
IMHO, making changes like this may cause problems in the future.
How much is really gained versus the potential risk?
I'm all for playing around and trying different things, but I think that's best done in a Test environment where a Backout plan is in place, if something goes wrong.
Right now I'm on a Win 7 OS that was installed in Oct 2009 and it is working very well.
Yes, it is very "Vanilla", but it works very well and reliably.
