Windows 7: logon denied only one user session is allowed

Question

Everything was working fine in Win7 Ultimate until one day, I could not switch users. I had to enable fast user switching in regedit for some reason and locked the computer, hit ctrl+alt+del (never had to do this before) and tried to log into another account but i got the message

logon denied only one user session is allowed

I've been googling for a while but I can't seem to find the answer. Could someone please help?

Solution 1

Looks like I had an issue with corrupted profiles. Finally fixed it. I can switch users now.

Solution 2

I am not sure..but i think you turn off Fast user switching,because it is a functionality on modern multi-user operating systems which allows multiple user accounts to log on to a computer simultaneously and then quickly switch between them without quitting applications and logging out.

The reason for turned off Fast user switching is

• First, this could be a security policy requirement. A security requirement might be that a user should completely quit all applications and log off from the computer after finishing his or her work on the computer.

• By disabling the fast user switching feature, you hide the Switch user button in the Logon user interface, in the Start menu, and in the Task Manager.

• Another reason could be performance issues. The fast user switching feature uses some system resources which can be freed in case the fast user switching functionality is not needed.

The above reason you tried to log into another account but you got the message

logon denied only one user session is allowed

I found that the PC had Cisco any Connect with VPN installed. Once I removed that the error went away and FUS started working.

I do not understand what you mean. Are you saying that I should disable FUS and not switch users on my PC?

[Dharma]

yes,you should disable FUS the problem will be solve(see that reasons). What the reason did you enable?
