Setting up WIndows 11 as a local account (without the MSA microsoft account)

How I clean up a clean install of Windows 11 and Edge
Tips and tricks for making Microsoft leave you alone while you use your PC.

If you don't want to bother with sign-in at setup, you have two options 
(three for Windows 11 Pro users):

During Windows 11 Setup, after selecting a language and keyboard layout but 
before connecting to a network, hit Shift+F10 to open the command prompt. 
Type OOBE\BYPASSNRO, hit Enter, and wait for the PC to reboot.

When it comes back, click "I don't have Internet" on the network setup 
screen, and you'll have recovered the option to use "limited setup" (aka a 
local account) again, like older versions of Windows 10 and 11 offered.

Windows 11 Pro users can do it without needing the command line to do it.
Proceed through the Windows 11 setup as you normally would, including 
connecting to a network and allowing the system to check for updates. 
Eventually, you'll be asked whether you're setting your PC up for personal 
use or for "work or school."

Select the work or school option, then sign-in options, at which point 
you'll finally be asked whether you plan to join the PC to a domain. Tell 
it you are (even though you aren't), and you'll see the normal workflow for 
creating a "limited" local account.

If you find yourself doing a lot of Windows 11 installs and don't want to 
deal with Microsoft accounts, Rufus lets you tweak the install media itself 
so that the "limited setup" options always appear, no matter which edition 
of Windows you're using.

To start, grab Rufus, and then a fresh Windows 11 ISO file from Microsoft. 
You'll also want an 8GB or larger USB drive; I'd recommend a 16GB or larger 
drive that supports USB 3.0 speeds, both to make things go a little faster 
and to leave yourself extra room for drivers, app installers, and anything 
else you might want to set a new PC up for the first time. (I also like 
this SanDisk drive that has a USB-C connector on one end and a USB-A 
connector on the other to ensure compatibility with all kinds of PCs.)

Fire up Rufus, select your USB drive and the Windows ISO, and hit Start to 
copy over all of the Windows files. After you hit Start, you'll be asked if 
you want to disable some system requirements checks, remove the Microsoft 
account requirement, or turn off all the data collection settings that 
Windows asks you about the first time you set it up. What you do here is up 
to you; all I usually turn off is the sign-in requirement, but disabling 
the Secure Boot and TPM checks doesn't stop those features from working 
once Windows is installed and running.
