 @Djmb, Welcome to HP Support Community!

I understand the inconvenience caused to you with the user accounts on Windows 10.

Method 1: I suggest you enter into safe mode and enable built-in administrator and check with the status of User profile service.

Step 1: Start computer in safe mode.

1. Type Settings in the search box on the desktop, select Settings.

2. Here select Change pc settings and then General.

3. Scroll down to Advanced startup, click Restart now.

4. Click on Troubleshoot, Advanced options, and Startup Settings.

5. Click Restart, select Safe mode and then press Enter.

Step 2: Enable Built-in administrator.

1. 1. Press Windows + X key together on your desktop screen.

   2. Click on Command Prompt (admin) to open Command Prompt.

   3. Type the following command and hit Enter:

•  net user administrator /active: yes (Check for the spaces)

             d.  Now log off from the current user and try to login to the administrator account that is enabled.  

Note: Please follow the same steps and type net user administrator /active: no to disable admin account after the troubleshooting is done.

Method 2: Try to create a new user account (Microsoft account) and check if you are able to access the content from your computer
