It’s been some time, but IIRC, I downloaded W11 onto a flashdrive with the MS media creation tool, booted of this drive and did a fresh install over my W10 installation. In this process I wiped my disk. Before that I googled what to do in order to be able to install without an internet connection. This allowed me to complete the installation without an MS account. This procedure might have changed since then. AFAIK there are still some hoops you can jump through in order to get it running without an MS account.

I use Windows 11 without an MS account and with Classic Shell. You can hardly tell a difference. I will continue using it. Because I can’t be bothered not to. It also came with my computer (well, W10 did but the upgrade worked painlessly).

A good compromise is to leave some “wild” patches for flowers and bugs and so on and use a mower robot to keep the rest short. Best of both worlds.

Retardistan is hogging the biggest portion of the IPv4 addresses for themselves. That’s why they have the worst IPv6 support. The need arose last in this part of the world.
