OK, that is optional, you can do it manually.
Is your computer part of a domain?
If it is just at home, disable this one.
This one is suspicious.
I have some theory that this is an application installed calling home.
Try disabling it and see what happens.
Sounds like an OEM pre-installed junk. Disable it and see what happens,
and then you can delete it when it is safe.
Same as above.
I would certainly investigate this one further.
Safe to disable or remove.
This is probably because you have media center enabled and possibly have
either a capture capable card or a TV tuner.
I would say leave those alone of you have the above.
See if it is this one.
Should not be disabled.
This one is safe to disable.
This one is related to Microsoft Office 7, from few reports that I have
seen, disabling this will render your copy of Office as non genuine.
The best approach at this point is to experiment disabling one by one
and see how the system behaves for couple of days.
I hope this helped.
