Installation:
(No need to install've motherboard driver later) just wow - 20 minutes and it was all over
Start:
perhaps wenns much is 20 seconds (I know it will continue to load in the background)
Control with keyboard: Topp (finally)
Control with mouse: Windows 7 has become nothing changed
Familiarization phase: not even half an hour
Reliability: So far not a single crash (but with Windows 7 was already so)
Detection of hardware, in particular USB - has become better than Windows 7
Buyer's remorse: No, definitely not
Apps: you can use - some are practical - you do not have, however, and are not critical to the use of Windows 8.1
Perhaps Microsoft has eliminated the update from 8.0 to 8.1 all error because me the switch from Windows 7 is so easy like. From my side, the transition has definitely paid off.
