If you're unable to log in to your computer using your Windows Account password, we suggest that you try the following recovery options:
Restore your device from a system restore point
- On you sign in screen, hold the Shift key down while you select Power> Restart in the lower-right corner of the screen.
- After your PC restarts, select Troubleshoot >Advanced option > System Restore.
- Choose a restore point. (Choose a date when you were able to log in to your computer)
Reset you device
If you don't have any restore points to restore your system or restoring did not resolve the issue, reset your device. If you choose the option Keep my files, this will reinstall Windows and keep your personal files. However, this will also remove apps and drivers you installed, and changes you made to settings. Choose Restore factory settings will remove everything but will reinstall Windows and some apps that came with your device.
- Hold the Shift key down while you select Power > Restart in the lower-right corner of the screen.
- After your PC restarts, select Troubleshoot > Reset this PC.
If resetting your device fails, the last option would be to restore your device using the recovery image. Only use this if none of the recovery options worked.
Feel free to post back if you need assistance.
