I have one machine that runs multiple instances of Windows virtual machines (separation of concerns.) They’re the least complicated machines (no unusual virtual hardware, and almost no installed extra software.) Presumably because they’re uncomplicated machines, they’re one of the first machines to get offered new updates (because there should be few blockers, and because I suspect a lot of people use VirtualBox like I do, and so Microsoft has lots of data on these types of machines.) A few of them were just offered the new Windows 10 20H2 update. This is mostly just flipping some registry switches and incrementing the build number by one. For most people already on Windows 10 20.04 this should be an easy and quick upgrade with little risk.
I went from:
20.04: Microsoft Windows [Version 10.0.19041.572]
20H2: Microsoft Windows [Version 10.0.19042.572]
It does, however, require a restart:
And the most noticeable change is a nicer looking (IMHO) Start menu, where there is less clashing of the colour scheme:
