Question How can I fix "The User Profile Service service failed to start" ?

[soapdodger]

The available space on my C (system) drive was low, so I moved the Users folder to my D drive and edited the registry accordingly.

After rebooting, I logged in to my work account and checked everything was okay. So far, so good.

Then I rebooted and tried to log in to my personal account and got the error message:

The User Profile Service service failed to start.​

​

User profile cannot be loaded.​

I am stuck on this login screen, with no option to switch to my work account, even after a reboot.

Unfortunately, I don't have any System Restore points or any kind of backup to rely on.

Any help will be greatly appreciated.

Are you able to access your admin account?

That's not how you move the contents of the Users folder to another drive. I suggest you move it back, revert whatever registry change you made, and then ask how to do the move properly.

I suspect you've also (and wrongly) moved the user registry hives.
