Step 1 - Make sure at least 2 users in place

Launch "netplwiz" as Administrator,

If only one user is in place, create another one, whatever it's a local user or a Domain User.

Step 2 - Enable User Switching

Launch "regedit" app, browse to: HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Policies -> System,

Then look for a entry named "HideFastUserSwitching". If not found, create a new "DWORD-32 Value" key, and set the value to "0".

Alternatively, launch "gpedit.msc" app, browse to: Computer Configuration -> Administrative Template -> System, Then find an entry of "Hide entry points for fast User Switching", set the value to be "Disabled".

Step 3 - Enable Multi-Users Online in the Same Time

Launch "regedit" app, browse to: HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Authentication -> LogonUI -> UserSwitch,

Look for a item named "Enabled", make sure the value is "1".

Alternative - Quick Switcher

Create a shortcut on Desktop, pointing to "C:\Windows\System32\tscon.exe".

If All above don't work out

  1. Update your Windows 11 system
  2. Run as Administrator to open Command Line Prompt and run: sfc /scannow.

The End
