Microsoft's OneDrive cloud storage service is installed on your PC by default, and it can cause some trouble when playing PC games on multiple devices.
I can understand how this might be annoying but I’m pretty sure it’s convenient for OneDrive users. Why doesn’t he just disable syncing on that folder? How many times is he changing PC?
Bought a Win 11 laptop recently (it's now a linux device), and on first boot up there was no way to gracefully decline using a Microsoft account to sign in. Luckily, I was in a hotel and couldn't connect to the wifi without going through a login page, so the lack of internet connection allowed me to set up a local account. In any case, if you're forced to log in with an MS account, OneDrive starts syncing right away. You can disable it, but maybe not before it's already done some damage.
You can skip the MS account during install, just select the domain join and then don't actually join a domain. You wind up with a single local user that way.
In addition to what the other user said, you can force it to make a local account by entering a "bad" email address. When I was regularly doing end user reinstalls, id regularly use "fuck@you.com" as my email, and for some reason, that account wasn't usable so it just had me setup a local account.
Will definitely file these methods away for the future. Microsoft just keeps getting skeezier and they didn't do this shit the last time I had to install Windows. This new laptop is the start of a transition to as close to 100% Linux as I can get.
