Where is this icon: 
located in Windows 10?
I tried searching in imageres.dll, shell32.dll and wmploc.dll using Resource Hacker, but couldn't find it there. I need a higher resolution (as much as possible) version of this icon.

It looks like the icon is in progman.exe, the Program Manager executable file. In Windows XP, you can still find the icon in %SystemRoot%\system32\progman.exe...
After rediscovering this, I think I remember that when you manually created a shortcut in Program Manager, the icons embedded in progman.exe were provided as default choices, or you could click a Browse button to open another .ico or .dll file like moricons.dll. But it's been so long ago, I don't have a copy to play with to confirm, and haven't been able to find information about it online.
It's in C:\Windows\System32\imageres.dll.
