Windows 10 won't save settings - preparing Windows at every startup

I have only one account with administrative privileges. However, at reboot, Windows 10 starts fresh. It says preparing system.

There are some programs I installed which remain, however, don't save settings. For instance, Mozilla Firefox won't stay default browser, it won't save my homepage, addons won't save. It's similar with other programs.

It seems like Windows just doesn't save settings but loads fresh at ever startup.

It's so frustrating. Can someone help please?

Thanks in advance.

It says I've been signed in with a temporary profile and in msconfig it won't go to normal startup.

Try this Windows 8 solution. It should apply to Windows 10.

Thanks for the reply. Will do.

In the meantime, I took sfc /scannow and it found some errors and fixed them. I guess it's good to go.

Still not resolved, however.

Come back with the results.

Thank you Snakeyes, it worked.
