disable Chrome’s AppID

• HKLM\Software\Classes\Chrome
• HKLM\Software\Classes\ChromeHTML\open\command\DelegateExecute

When you delete the registry keys that enable DelegateExecute, they disable Chrome’s AppID. But the problem, is that when Chrome updates itself again, you may find that these keys has been re-created. In such a case, you may have to again delete these keys.

Restart your Windows PC.

If this does not work, delete the start screen or start menu Chrome shortcut and navigate to the following folder:

C:\Users\username\AppData\Local\Google\Chrome\Application

Check if clicking on chrome.exe works. It should. If so, pin its shortcut to the start screen. It will now work correctly.
