Windows setup pushes hard for a Microsoft account, and the internet pushes back just as hard. Both sides leave things out. Here is the honest trade, feature by feature, so you can choose on facts instead of pressure.
This is not really an argument about sign-in screens. It is about where your recovery keys live, whether your settings follow you, and how much of your PC life touches Microsoft's cloud. Read the two columns, then pick — and whichever you pick, do the two safety steps at the end.
The biggest item is invisible until disaster day: on most new PCs the drive is encrypted, and the BitLocker recovery key is automatically saved to your Microsoft account. If Windows ever demands that key after a hardware change or a failed update, account users look it up online; local users who never saved it are locked out of their own data.
After that: settings and saved Wi-Fi passwords roam to your next PC, Find My Device can locate a lost laptop, and the Store, Office and OneDrive all sign in with the same identity.
A local account keeps the sign-in entirely on the machine: no email address attached to the PC, no account sync, and a password that works with zero internet. For a shared family PC, a workshop machine, or anyone who simply does not want a cloud identity on their computer, that is a legitimate and complete choice — not a broken one.
The costs are equally real: you become your own recovery service. Forget the password with no reset disk and no second admin, and the way back in is painful. Lose the BitLocker key, and the data is gone by design.
A Microsoft account does not mean Microsoft reads your files — your documents stay on your PC unless you put them in OneDrive. A local account does not make Windows stop sending required diagnostic data — that is a separate setting, covered in the privacy page of this series. And you can start with one and switch later in Settings → Accounts; the choice is not a life sentence either way.
Windows setup flows change between versions — newer builds hide the local option deeper, and the workarounds change with them. What does not change is the trade above.
These two steps matter more than the choice itself:

Windows Update works fully. The Microsoft Store lets you browse and install free apps in most cases, though purchases and some apps will ask for a Microsoft account at that point.
If you signed in with a Microsoft account, it is usually listed in the recovery keys section of your Microsoft account online. With a local account and no saved copy, there is no back door — that is exactly why the setup-day save matters.
