Build 10586 update: "Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3124262)". It's now 10586.71.
interesting and on the other hand if we use a google, apple or microsoft smartphone ain't the same as like using a tor network or anything like that
[sarcasm] Good idea! Just keep using Google, Apple or an MS Smartphone, use Tor too, and you'll be safe [/sarcasm] Just kidding
If you could downgrade that is the question in my experience it is very easy to upgrade and very hard to downgrade you have to mess with the registry because the installer will not let you proceed if it reads that you have a newer version from registry. The only option given is then install without apps and your programs.
