The message indicates a sign-in problem with Windows using a Microsoft account credential cached on the device, not with the online Microsoft account itself.
Use these steps in order:
- Verify the Microsoft account works online
- On another device or browser, go to the Security basics page and sign in with the new password.
- If sign-in succeeds, the account and password are valid.
- Try Windows sign-in recovery options
- On the Windows sign-in screen, select I forgot my PIN or Sign-in options (if available) and choose password sign-in instead of PIN.
- If the password is not accepted, use the guidance in Troubleshoot Problems Signing In to Windows to pick the right recovery path:
- For a forgotten Microsoft account password, use Forgot your Microsoft account password.
- For Windows sign-in issues in general, follow Change or reset your Windows password from another admin account if one exists.
- Use the Sign-in Helper if the account is not recognized
- If Windows reports the account or username is not recognized, use the Sign-in Helper tool described in Troubleshoot Problems Signing In to Windows and I can't sign in to my Microsoft account. This tool checks for common account issues and guides through recovery.
- Recover the Microsoft account if access is lost
- If the password stopped working or the username is not recognized anymore, follow the steps in I can't sign in to my Microsoft account:
- If the password is forgotten, use Reset your password.
- If the password is known but not working, use the Sign-in Helper tool.
- If the username is not recognized, see My username has stopped working.
- If the password stopped working or the username is not recognized anymore, follow the steps in I can't sign in to my Microsoft account:
- If Windows sign-in still fails
- If none of the above resolves the issue and there is no other local administrator account on the PC, the remaining options are:
- Use any available password reset or recovery media previously created for a local account.
- As a last resort, back up data if possible (for example, by removing the drive and attaching it to another PC) and perform a clean install of Windows, similar to the resolution described in the Dell Rugged Laptop case where reformatting and reinstalling Windows was required when PIN and password recovery failed.
- If none of the above resolves the issue and there is no other local administrator account on the PC, the remaining options are:
For future prevention, once access is restored, ensure there is at least one additional local administrator account or a password reset disk for local accounts, so that a cached-credential or PIN issue does not fully lock out the device.
