There is currently a weird bug in the Windows 11 Setup procedure. When selecting the Language, Keyboard/Input Methods and Time/Currency, you can select either "English (World)" or "English (Europe)" as the region. If you choose one of these two options then the Microsoft operating system will be installed free of bloatware!
So simply choose "English (World)" or "English (Europe)" and later, when installation has completed, change the Region to your correct region.
This bug will probably be fixed in 6 months or so, but in the meantime it is a useful trick!
