No problem at all with 10. I update laptop and PC with no problems. I use Chrome Browser. That way my PC, Laptop, Tablet and phone can all be synced.
Same here , except for one more important step........
I have a 4 Terabyte internal Hard Drive and it is backed up ( byte for byte, zero's and one's ) to an external 4 Terabyte Hard Drive every night....
All this is automatically done with no intervention by me.......I have absolutely no fear of Viruses, malware, etc...
