I did take a look at some of the other services. Some of them had greyed out options and some didn't.
I've examined the Task Manager in the past. No problem with anything else I run. Every time this computer has run slow, Updates happened to be downloading. So I believe it's a pretty informed "guess." I was able to stop them and continue working (as it always sped right up). After some update, now I can no longer do this. All the options are now greyed out.
