Windows cannot log you on because your profile cannot be loaded – Remote Desktop error

If you get the error message Windows cannot log you on because your profile cannot be loaded when you try to sign into a user account on a local machine or when you try to establish a remote connection via Remote Desktop Protocol, but the connection fails, then the fixes presented below should help you resolve the issue depending on the scenario. Let’s see these applicable fixes in detail. The issue at hand can occur in one instance if the computer you are trying to log into has too many users connected — in which case, Fix 3 applies. Another instance of this error occurs when the NTUSER.DAT or UsrClass.dat file is defined as read-only, or the profile user lacks the appropriate permissions for these two .dat files — in which case, the Fix 1 & Fix 2 applies respectively. New user profiles are derived from C:\users\default\ during first-time account logins. The NTUSER.DAT file in later versions of Windows is located in C:\Users\default\ntuser.dat. The UsrClass.dat file is typically located in C:\Users\AppData\Local\Microsoft\Windows.

1] Uncheck the Read-only option for the NTUSER.DAT & UsrClass.dat file for the profile

This fix requires you to check whether the Read-only flag is set on the NTUSER.DAT or UsrClass.dat file for the profile that fails to load. If so, in File Explorer, select the file for the relevant default user or cached user profile and then clear the Read-only checkbox to resolve the Windows cannot log you on because your profile cannot be loaded error that has been triggered on your machine.

2] Assign Full control permissions to the NTUSER.DAT & UsrClass.dat file for the profile

This fix requires you to check and assign the Full control permissions to the NTUSER.DAT & UsrClass.dat file in the cached profile directory that fails to load. You may notice the Everyone user group isn’t listed in the Advanced NTFS File System ACLS on DAT files.

3] Log the user off or disconnect idle user sessions in Task Manager or remotely log off the user

This fix requires you to log user(s) off or disconnect idle user(s) sessions in Task Manager or remotely log off the user. If for some reason you’re unable to sign out a user, you may want to disconnect idle user sessions by following these steps:

Open Task Manager on the server while actively logged in as a local administrator.Click to expand More details.Next, select the Users tab.If the Status shows as Idle for a user, you can select the user, and then select Disconnect.

Alternatively, you can remotely log users out of the system with the following command: This command will remotely log session TEST01 out of the server with a computer name SERVER01. Read: How to increase the number of Remote Desktop Connections in Windows That’s it!

Why does my PC say the user profile cannot be loaded?

There could be several reasons why you may get the user profile cannot be loaded error on your PC – the most likely and common sense is your user profile is corrupted. If you are experiencing the issue because of a startup error, shutting down and restarting the computer will most likely resolve the problem. Due to an abnormal or unexpected shutdown of your Windows 11/10 device, the user application cache located at C:\Users<username>\AppData\Local\Packages may get corrupted.

How do I reset my Windows profile?

To reset your Windows profile simply requires you to delete your user profile and then re-create a new profile. You may want to do this if you’ve identified the user profile is damaged (due to file system integrity compromised because of disk write errors, power outages, or virus attacks) and cannot be repaired. Resetting your PC depending on the option you selected, all the personal files and user accounts on your PC will be removed.
