Hello Jim Carter,
I’m sorry this has continued after three clean installations, even after you receive and enter the verification code.
When you say the account works on your laptop, do you mean signing into Windows, or signing into the Microsoft account website in a browser? Please try a fresh sign-in through a private browser window at Microsoft account.
Please also share:
- A screenshot of the exact error when switching from the local account to your Microsoft account, with your email address and other personal details hidden.
- Your Windows version and OS build, shown by pressing Win + R, entering
winver, and pressing Enter.
You can also use Microsoft’s Sign-in Helper to check for account sign-in problems.
These details should help distinguish an account-access problem from a failure connecting the account to Windows, without asking you to reinstall again.
