Hello,
Thank you for posting in Q&A forum.
I suggest you try changing the password for the Administrator account in safe mode, please refer to the steps below:
- Click "Start" > "Power", then hold down the Shift key and click Restart. Your computer will restart and display the Windows Recovery Environment. From here, go to Troubleshoot > Advanced options > Startup Settings > Restart.
- Press F6 to select "Enable safe mode with Command Prompt". In the Command Prompt window, type "net user Administrator newpassword" and press Enter. Replace "newpassword" with the new password you want to create.
I hope the information above is helpful.
Best regards
Zunhui
