Sure you can. I, as a tech savvy person, can debloat Windows 11. If I dare to do it. If I know I can do it. If I search for information on the internet on how to do it. If I know how to search and follow those instructions. If I follow all the steps (and hope my tutorial covers everything). If Microsoft doesn’t push an update to bloat it again.
And with that, well I still don’t know how to install it without a Microsoft account. It’s so incredibly user hostile that even the insufferable Apple Walled Garden don’t force you into all of this shit.
