Cant log in to Windows 10 as local user

I understand your concern and will assist you to resolve this issue.

I suggest you to follow the steps below and check if it helps.

Method 1: System file check is a utility built into the Operating System that will check for system file corruption. The sfc /scannow command (System File Check) scans the integrity of all protected operating system files and replaces incorrect, corrupted, changed, or damaged versions with the correct versions where possible.

1. Press Windows key and X at the same time.
2. Choose Command Prompt (Admin) from the context menu.
3. In the command prompt, type sfc /scannow and hit Enter.
4. Exit command prompt.

Hello,

Thank you for posting your query in Microsoft Community.

You may download the Windows 10 ISO and create a Media Creation tool and then perform Startup Repair.

Refer to the following link:

http://www.microsoft.com/en-us/software-download/windows10

(Refer to the section "Installing Windows 10 using the media creation tool " in the above article for creating the tool).

Once you have the installation media, follow the steps: 

1. Start your computer from the installation media.      Insert the disk or USB stick and restart your computer. If you see a      message asking you to “Press any key to boot from DVD,” do so. If you      don’t see the message, you might need to change the boot order in your      computer's BIOS settings so that it first starts from the disk or      USB. When you see the 'Install Windows' page, tap or click 'Repair your      computer' link to start the Windows Recovery Environment.
2. In the Windows Recovery Environment, on the Choose an      option screen, click 'Troubleshoot'.
3. Click, ‘Advanced Options’ and then click on 'Startup      Settings' and select ‘Restart’.
4. After this complete the repair and see if you are able      to boot in to your computer.
