Windows 10: The User Profile Service service failed the sign-in...

...User profile cannot be loaded.

I am using a dual-boot system with Windows 10 & Ubuntu. And I have for sometime now without a problem.
Maybe the newest thing I installed has something to do with this (?). It was Ext2Fsd
This morning I switched to Win10. Using Grub2, I believe I chose Windows UEFI bkpbootmgfw.efi.
Only to find this message as a result of trying to login with my usual PIN #. Then I switched to use my password, and it worked. However, everything continued loading very, very slow. Slower than usual that's for sure. Once it seemed stable, I noticed the Windows key was not available. Also Ext2fsd had not loaded on its own, so I manually made it run. I logged off, but this time even with my password it would not log me in. I rebooted, but this time I chose Windows Boot Manager (UEFI on /dev/sda7) (I think).
Windows started doing some fixings, and said it would be over an hour. It really only was a few minutes, but I was not there when it was done. It rebooted on its own, but it went to Ubuntu as it is the 1st on the Grub2 list. I wasn't able to continue checking on this as I had to go to work.

Other people have advised to gain access to another Win10 installation (on PC or a USB drive), to copy the c:/Users folder and replace the one in your pc.

What do you guys think?

Thanks in advance,

DPC

Sounds like you have logged into a temporary profile. Try restarting your computer a few times. Press Control + Alt + Delete

Click Sign out

At the sign in screen, click the power button, then click Restart. Do this a few times then try signing again. If the desktop still does not show up, then you will need to create a new local user account.

Press Control + Shift + Esc

Click File > Run new task

Type: control userpasswords2

Click Add

Enter a user name

Password, confirm it, create a hint

Click Next

Click Finish

Click OK

Sign into the new account.

Open File Explorer on the Taskbar > This PC

Open the drive where Windows is installed

Open Users

Look if your old account old is there with your files

If they are, you can copy them over to the new account.

 

Can you check your registry? Make sure your profile doesn't have a .bak to it. If it does delete the .bak and if you have a temp profile add it to that. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
