If you are using the Windows 10 system, you should pay attention, because Microsoft will upgrade some old versions of the system to Windows 10 20H2 (update released in October last year).

In particular, Microsoft has enabled a new interface in Windows 10 20H2. Specifically, the background color blocks of the dynamic ceramic stickers have become more shallow and soft, and the interface of the start menu has also been more compatible with the overall system, that is, Microsoft uses The translucent background color block replaces the high-contrast dynamic ceramic stickers of the previous “hot eyes”, and it supports lighter and darker themes more harmoniously.
For the mandatory upgrade of Windows 10 20H2, Microsoft has two main considerations. The first is that Windows 10 1903/1909/2004 versions are gradually discontinuing support, and the second is to keep the device system smooth.
If you do not want Microsoft to force a device upgrade, please make sure you are running Windows 10 2004 version or 20H2 version.
