Microsoft has been releasing these "preview" updates towards the end of the month before they release it on the following Microsoft Tuesday. Like this one, which came out on November 22nd.
Windows 11 is an "optional" upgrade. Windows 10 will be supported until 2025.
So you can pretty much just ignore the banner until you are ready to upgrade to Windows 11.
Also, to make life easier, the owner(s) of Ten Forums have already created Eleven Forum for your viewing pleasure. So you can "skip ahead" in your reading.
