Pin to Start in Windows 10
You can pin a shortcut to the Start menu in Windows 10. Note that you can’t pin a document itself to the start menu, just a shortcut to it.
Here’s how:
To add Pin to Start to the context menu for a file, you will have to modify the Windows Registry. But first, create a system restore point!
Now, to add Pin to Start easily, copy-paste the following in a Notepad and save it as a .reg file:
Windows Registry Editor Version 5.00
; Created by TheWindowsClub [HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\PinToStartScreen] @=”{470C0EBD-5D73-4d58-9CED-E91E22E23282}”
Now click on the .reg file to add its contents to your registry. You will be asked for confirmation, so you may click Yes, to add it.
