Win11

Today I was brave and installed Windows 11 (on top of my Win10, so only a new operating system).
My Windows Update was having an issue with one KBsoandso. Hence it did not offer an upgrade to Win11. I expected the upgrade would override this problem, so I just followed the (three) steps for the upgrade.
It took a couple of hours, obviously quite a lot was downloaded and installed, but then everything worked as if nothing had changed. Okay, some things look different and some settings were as if I was a beginner. But I was surprised how easy it was and how close to "my" Win10 it still was.
Now D.'s laptop and my desktop need either an upgrade to Win11. And if not possible we might move them to Linux of some kind, Ubuntu probably.
