Enabling the shell improvements
It is possible to enable the new Start menu with theme-aware tiles and the new notification toasts experience from version 20H2 and Dev Channel Iron builds. To do it, first make sure you have installed the optional KB4568831 cumulative update on your PC. Then, copy the following script into a blank Notepad document, save it as a  file, run it, and reboot: Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\0\2093230218] "EnabledState"=dword:00000002 "EnabledStateOptions"=dword:00000000
