Windows 10 20H2 (the new naming convention for the Windows 10 bi-annual major updates) is the October 2020 major update. Note that Microsoft is rolling out this update on a metered basis and not everyone will get the update at the same time.
Here is how you can get it now.
Not quite the large scale updates seen in previous updates as Microsoft is making the Spring of 2021 update the next large scale update and this Fall’s (20H2) update a medium (more than a monthly / patch Tuesday update but with less new features than previous Fall updates).
B) If at all possible create an image back backup of your computer’s disk drive (all partitions, not just a “System Backup”) to an external USB drive and create the “Recovery media” if you just installed the backup software and used it for the 1st time. Should the update fail or cause other issues you can use the backup to restore your current version of Windows 10.
C) Laptop users should be plugged into an AC power source, DO NOT run on battery power.
D) If you manually run Windows Update (Start / Settings / Windows Update) and after installing any monthly updates you see “Feature update to Windows 10 20H2” listed all you need to do is click on “Download and install”. Note that Microsoft is rolling out this update on a metered basis and not everyone will get the update at the same time.
