Perform another reset from Windows Recovery Environment and select Remove everything; Keep my files can preserve user information, whereas Remove everything deletes personal files, apps, and settings, including the mistaken sign-in configuration.^1^
Reset from the sign-in screen
Because you cannot sign in:
- On the sign-in screen, select the Power icon.
- Hold down Shift and select Restart.
- When Choose an option appears, select:
Troubleshoot → Reset this PC.
- Select Remove everything.
- Select Cloud download if available, or Local reinstall.
- Follow the prompts and allow the reset to finish without manually switching off or restarting the laptop. A reset can display a black screen for an extended period and restart itself.^1^
Warning: “Remove everything” erases all files, installed applications, and settings. If anything important was added since setup, it must be backed up first. If Windows asks for a BitLocker recovery key, that key is required to continue.^2^
Set up the correct parent account first
When Windows setup starts again, enter the correct adult/parent Microsoft account as the first user. If the laptop is for a child, the accepted setup guidance is to configure the family organizer’s account first, ensure the child belongs to that Microsoft family group, and then add the child under:
Settings → Accounts → Family
Select the child’s account, allow sign-in, and restart the laptop.^3^
If the wrong account still returns
If Remove everything completes successfully but the old address still appears:
- Use HP recovery media for the exact laptop model, or reinstall Windows using installation media.
- Be aware that this also removes everything from the device.
- Manufacturer recovery media is preferable when available because it normally includes the model-specific drivers and factory applications.^2^
Windows 10 support ended on October 14, 2025. If this HP model supports Windows 11, upgrade after setup so it continues receiving security fixes.^1^
