Planning to upgrade to Windows 11? A checklist before you do

I don't know what else to call it: the Windows 11 upgrade situation is a confusing mess. Depending on when your PC was built, which components you chose, and how it was configured, there's a decent chance Microsoft will try to scare you away from installing the free upgrade, which is available a day early today. Millions of people will likely be told their systems are incompatible, and Microsoft is reserving the right to withhold security updates if you install on older systems.
