I wanted to add a “Bash Here” context entry when I right click on a directory:

This Bash Here would open that directory in Cygwin (mintty).
My current PC is fairly regulated, so without admin rights and thus I can’t use the CHere option which I would normally use.
I just created the registry keys via regedit and that works fine.
You can use two options:

1. Import the registry file mentioned below
2. Create the keys yourself

1. Import the registry file

Create a file called cygwin_bash_here.reg with the following contents:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\Directory]
[HKEY_CURRENT_USER\Software\Classes\Directory\shell]
[HKEY_CURRENT_USER\Software\Classes\Directory\shell\bashhere]
@="Bash Here"
[HKEY_CURRENT_USER\Software\Classes\Directory\shell\bashhere\command]
@="C:\\cygwin\\bin\\mintty.exe"

Save the file and double click on it to import it to the registry.

2. Create the keys yourself

1. Open the registry editor: Start – Run – “regedit”
2. Open the following path: HKEY_CURRENT_USER\Software\Classes
3. Create key: “Directory”
4. Inside Directory, create key: “shell”
5. Inside shell, create key: “bashhere”
6. Inside bashhere double click on the standard key and insert text “Bash here” without quotes (This is the text which is displayed in the context menu.
7. Inside bashhere, create key: “command”
8. Inside command, double click on the standard key and insert text “C:\cygwin\bin\mintty.exe” without quotes. Important: This is the command which is run. Please change directory to your cygwin directory

Conclusion

Both options will create a context menu item which opens Cygwin at your current windows directory!
