Backed up my entire PC to my external HDD last night, then installed Win 10. Went as smooth as a baby's bottom, no hiccups or problems of any sort. Didn't do the express install, I used the options to switch off as much of the tracking stuff as possible.

First impression is that, for the average Joe like me who just does a bit of surfing the web, online shopping, email, Farcebook, The Mudcat Mental Asylum, a few spreadsheets, a bit of word processing, it's not much different to Win 8.1 in terms of use. I realise that there's probably more going on under the surface that the tinfoil-hat brigade are bricking it over, but for what I imagine are the vast majority of people, it's very similar to its predecessor.

Everything seems to work fine - my internet security, Office 2013, Reaper, Audacity, Pro-Tools First, FlightRadar 24, Photoshop, everything.

Early days, but looking good, at least for the moment.
