This is actually 2 questions.
 When I view Windows Task Master, it says I am running 43 services. Some by Microsoft, others by apps. I would like to decrease this number of services running by 10 to 15 to bring the total near 30 or less. The question is: which services are "Vital" and which can be turned off?
 Under the Windows Directory, I see several "blue" entries relating to Windows Upgrades. I have been told that those entries don't need to be there and that they just take up disc space. Can these entries be deleted? (Oh, there is 1 that is black)
