re: advantage/disadvantages of W10 vs W7
I never saw Win-10-nic as being, in ANY way 'faster'. in fact, some things are DEFINITELY slower. Some of the SSD drive owners say the opposite, though, so I'd guess that the kernel now favors SSDs over spinny-drives, so YMMV. Personally, I think a properly designed kernel would have been faster for ANY drive, and not waste a pile of time with paranoid re-re-reads of the registry [among other things].
Another factoid that's interesting: check out the latest 'statcounter'
http://gs.statcounter.com/#os-ww-weekly-201531-201639
it shows a DEFINITE DECLINE in Windows 10 usage, and a corresponding BUMP UP in Windows 7 usage. Coincidence? I don't think so... but it's early in the week, and the latest numbers will usually drop a bit by the following monday. we shall see, I bet!
