How to Fix "The User Profile Service service failed the sign-in. User Profile cannot be loaded." Error in Windows 10


A user profile is a collection of settings that make the computer look and work the way you want it to for a user account. It is stored in the user's C:\Users\<user name> profile folder, and contains the account's settings for desktop backgrounds, screen savers, pointer preferences, sound settings, and other features. User profiles ensure that your personal preferences are used whenever you sign in to Windows.

A user's profile folder also contains their personal folders such as the 3D Objects, Contacts, Desktop, Documents, Downloads, Favorites, Links, Music, OneDrive, Pictures, Saved Games, Searches, and Videos folders.

If a user gets the The User Profile Service service failed the sign-in. User Profile cannot be loaded. error message when trying to sign in to the account, the profile may be corrupted or the profile path is not correct in the registry for the account.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

7 Do step 8 (SID without .bak), step 9 (SID with .bak), or step 10 (SID with and without .bak) below depending on if the SID key (ex: S-1-5-21-....-1003) from step 3 has instances (ex: "S-1-5-21-....-1003" and/or "S-1-5-21-....-1003.bak") with or without .bak at the end.

2) Change the value data to 0 (number zero), and click/tap on OK.
