How to change the user avatar of Win10 Build 9926 into a circular user login interface?

When you see this rounded user login avatar, you will be a bit strange but feel very cute. In fact, you can activate the new function that is not started by default by simply modifying the registry - brand new User login screen.

To activate the login screen using this enhanced version, do the following in Windows 10 with version number 9926:

1. First open Regedit.exe

2. Access HKEY_LOCAL_MACHINESOFTWARE\\Microsoft\\Windows\\CurrentVersion\\

Authentication\\LogonUI\\TestHooks

3. Double-click the “Threshold” key to change it to the pop-up dialog box. “1”

4. Close Regedit.exe

After the modification is completed, the new lock screen icon and the round user icon will be found when returning to the login screen, although No other new features have been added, but they have a different experience than Windows 8 systems.
