It would be extremely useful to be able to compare 2 selected device. If I checkbox 2 devices that should have all the same processes, services, startup programs etc. I can see if a service is missing on one and quickly determine that that may be the problem e.g. "why is the printer working on Device Computer-1 but not Computer-2 when they are supposed to have the same settings? Oh, I can see via this comparison that Computer-2 has the printer spool service set to Disabled."
