Disabling fast user switching in Vista

[andrewbb]

In XP you could disable FUS by setting AllowMultipleTSSessions to 0 in
either
- WindowsNT\CurrentVersion\Winlogon, OR
- Windows\CurrentVersion\Policies\System (the policy took
precedence)

That value could be changed in real-time.


But they don't seem to work in Vista even after a reboot. Is it not
possible to disable FUS anymore?

Thanks, they changed the name to HideFastUserSwitching

You used to be able to make the change programmatically and the change
would be immediately reflected on the Start menu. Vista caches the
state and doesn't reload until you logoff. Is there any way to force
Vista to change it's Start menu to remove the Switch Users in real-
time?

Works fine here. I used Regedit.exe to create/alter the values, and the changes are dynamic. I see that you're using a program to write that value. Can you try Regedit.exe to change the "HideFastUserSwitching" value and observe what happens?
