Hi Ron,
After using Windows 10 for the last 3 months, i have changed my opinion from not liking the OS to enjoying the OS. Yes the initial phase was tough since getting used to Windows 10 did take some time. However, once you get used to it and understand the shortcuts, its a breeze. Just recently subscribed to Office 365 and that took care of the productivity part. I would say Office 365 is optimized for Windows 10 and the 1TB OneDrive storage that i get with O365 helps keep my files secured.
Regards,
Edwin.
