The available space on my C "system" volume was low, so I moved the Users folder to my D "data" volume and edited the registry accordingly.

After rebooting, I logged in to my "1st" account and checked everything was okay. So far, so good.

Then I rebooted and tried to log in to my "2nd" account and got the error message:

The User Profile Service service failed the sign-in.

User profile cannot be loaded.

I am stuck on this login screen, with no option to switch to my "1st" account, even after a reboot. No alternative accounts are shown in the usual place at the bottom-left of the screen.

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

Any help will be greatly appreciated.

It seems that moving the Users folder to another drive and editing the registry has caused an issue with your user profile. This can sometimes happen when you manually change the location of the Users folder. To resolve this issue, you can try the following steps:
  1. Restart your computer and boot into Safe Mode. You can do this by pressing the F8 key repeatedly after the BIOS screen appears.
  2. Once you are in Safe Mode, press the Windows key + X and select "Command Prompt (Admin)" from the menu.
  3. In the Command Prompt window, type the following command and press Enter: net user /add Replace with the name of your personal account.
  4. Next, type the following command and press Enter: net localgroup administrators...

  4. Next, type the following command and press Enter: net localgroup administrators /add This will add your personal account to the Administrators group.
  5. Restart your computer and try logging in to your personal account again. If the above steps do not resolve the issue, you can try repairing your user profile. Please note that this method may cause some data loss, so proceed with caution:
  6. Restart your computer and boot into Safe Mode.
  7. Press the Windows key + R to open the Run dialog box, then type regedit and press Enter to open the Registry Editor.
  8. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
  9. Look for the subkey that corresponds to your personal account. The subkeys are named with a long string of numbers and letters, followed by .bak. For example, S-1-5-21-1234567890-1234567890-1234567890-1001.bak.
  10. Right-click on the subkey that ends with .bak and select Rename. Remove the .bak extension from the subkey.
  11. Close the Registry Editor and restart your computer.
  12. After restarting, try logging in to your personal account again. If none of the above steps work, you may need to create a new user profile for your personal account. This will involve creating a new account and transferring your personal files and settings to the new profile. I hope this helps resolve your issue. Let me know if you have any further questions or concerns.
