Windows 11 download, EU version is not there yet but maybe try to use a VPN from your router or so to get an EU version saved somewhere in the OS so that you benefit from the laws in the future.

But that is optional.

If you are on Linux use balena etcher for flashing. Better is to use Rufus on an existing Windows, as it can remove some nasty things directly like online account and even hardware requirements.

Remove all other drives if there are any, Windows destroys everything (rule of thumb)

Plug the stick in, begin installation.

When "sign in with MS account" shows up and there is no "I have no internet" option, use Bypass 1 from this website or try the others.

Choose Windows 11 pro or even enterprise if possible as these have less bloat. If you are feeling adventurous, unlock any Windows version and Office with this tool

After install, get BCUninstaller and WinUtil from Chris titus (run the command in the administrator powershell window).

Remove as much bloat as possible, winutil allows you to remove edge. Install vlc, firefox/brave, 7zip and maybe more through winutil.

Winutil also allows debloating and removing telemitry (but it uses the shitty ShutUpWin10 which is stolen from DoNotSpy10 so maybe use that too). Performance mode and disabling "feature updates" might also be wanted.

The DNS settings are a bit broken, so better change the DNS settings manually to some of these servers

Use SimpleWall to block tracking connections. Portmaster broke connectivity check or something for me on Win11.
