Just installed win 10.
Played / looked around for hours and have zero issues with it.
I am happy. Sofar
4 more pc's to go.
I am not concerned about the OS taking control of all updates as log as they don't crash. I don't know a person that understands the internal changes of hundreds of patches a year to an OS. I (like 99%) just throw them in and hope for the best. OR hand-dracally click one at a time and reboot to test yourself (times hundreds of patches times 5 pc's + 2 android phones + 2 tablets). Ain't happening. I trust the OS maintenance crews.
Happy camper so far.
