    Your solution assumes the ability to enable the hidden administrator account, log into Win 10 in Safe Mode, and apply your solutions. But, what if, as in my case, every user account, including the Administrator acct, faces the same Profile Service Failed issue and there is absolutely no way to log into the Safe Mode? Now, what are you going to do? How are you going to solve it?

      Thank you for your question. Please follow these steps: Restart your computer and tap F8. Choose Safe Mode with Command Prompt. If you cannot log into Safe Mode with Command Prompt, reboot and hit F8 until you see the menu again, then highlight Repair Your Computer and press Enter. Try logging in here, choose your user from the dropdown menu, and type the password. Choose Open Command Prompt and type: net user administrator password /active:yes (here again, you can specify a password). Close the Command Prompt and click Restart. Boot up again, pressing F8, but choose just Safe Mode this time. You should be able to log in as Administrator with the password you set
