Please follow the steps to enable the Build in Administrator:
Use the power button on the sign-in screen to Shift+Restart. This will take you to the recovery boot menu.
Click Troubleshoot, Advanced options, Startup settings. When given the choice of startup options, try booting the PC in Safe Mode with Command Prompt.
If you can get to a CMD window, enable the built-in administrator account:
net user administrator /active:yes
Then restart and sign-in as the Administrator account.
After you log in, create a new user account using your Microsoft account. Check how many users are configured for (control panel>User account) and if you see your old user account, you can transfer your data from the user folder to the new account.
Do not forget to disable the inbuilt user account as this is only good for troubleshooting purposes.
Open CMD (Admin) type: net user administrator /active:no
