Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Background\shell\mingw64]
@="MinGW &64 Bash Here"
"Icon"="\"C:\\msys64\\msys2.ico\""

[HKEY_CLASSES_ROOT\Directory\Background\shell\mingw64\command]
@="C:\\msys64\\msys2_shell.cmd -mingw64 -where \"%V/\""

[HKEY_CLASSES_ROOT\Directory\shell\mingw64]
@="MinGW &64 Bash Here"
"Icon"="\"C:\\msys64\\msys2.ico\""

[HKEY_CLASSES_ROOT\Directory\shell\mingw64\command]
@="C:\\msys64\\msys2_shell.cmd -mingw64 -where \"%V/\""

The command lines from @MacGyver27's .reg file worked fine for me so I didn't need to modify it. But here are some things to add that people may want to change to the above files:

• If you add a key to HKEY_CLASSES_ROOT\Directory\shell, the menu item will be displayed when you right click on a folder in explorer. If you add a key to HKEY_CLASSES_ROOT\Directory\Background\shell, the menu item will be displayed when you right click on an empty area in a folder in explorer. If you add a key to HKEY_CLASSES_ROOT\Drive\shell, the menu item will be displayed when you right click on a drive. You may or may not want to add all three.
• If your context menu is too cluttered you may want to enable the item for SHIFT+right clicks only. In this case you should add the following:

[HKEY_CLASSES_ROOT\xxx\shell\<msys2|mingw32|mingw64>]
"Extended"=""
"ShowBasedOnVelocityId"=dword:00639bc8

For those who want make's autocompletion to work, replace the /command lines with this command, as applied in here.

The only option that worked for me with fresh MSYS2, thank you so much

C:\\msys64\\msys2_shell.cmd -mingw64 -here works for me.
