I have updated my laptop and the home computer up to Windows 10 Pro from Windows 8.1 and Windows 7 Ultimate respectively. So far having a positive feeling from the new system, runs quicker, the interface got better. The only problem I am having is inadequate video playback on my laptop through the embedded Windows player, obviously the appropriate driver is not available yet (Intel HD videocard) but that is not a big problem as I use VLC player and there video runs as it should. And I am sure that the corrected driver should be available soon as my equipment is quite fresh (manufactured in 2013).
