Why is this a bad thing?
Shouldn't windows decide how many resources excel will need and allocate things
accordingly?
From a non-technical person, I'd say let windows be windows and let excel be
excel.
On the other hand, do you have a co-worker with the same set up as you (and
about the same number of applications/processes running)?
If you do, what do they show?
(This non-technical person doesn't have a response in either case, though.)
