I\'m using msysgit running on Windows XP.
Tried Ctrl+V, Right click, Middle click, google... no luck.
if your intention is copy/paste comments for git commits, try set the enviromental variable EDITOR as your favorite plain-text editor (notepad, notepad++ ...) and when you will commit, don't give him the -m option and Git will open your favorite editor for copy/paste you comment
Use Shift + Insert like in linux bash
Edit: It works even in putty.
I'm back to Windows for the first time in a long time and this got me cursing like a docker. I finally found this:
Enabling Ctrl+Shift+letter shortcuts got me to a Linux-like behaviour that has lowered my blood pressure. Ctrl+Shift+C/Vnow works.
This is suggested by the github help page:
clip < filename
this copies the contents of filename to the clipboard and is useful for doing things like copying your id_rsa.pub to a web form.
Press Insert.
Also, to copy from the window, try clicking the console's window icon (topleft) and choosing Edit -> Mark, then drag a box on the text, then press Enter. (You can also paste via the window icon menu, but the key is faster.)
UPDATE
Starting from Windows 10 the CTRL + C, CTRL + V and a lot of other feature are implemented in conhost.exe so they should work with every console utility on Windows. (You have to enable Properties -> Option tab -> Quick Edit Mode)

Ctrl + insert did it for me in Windows.
