stop Windows from wanting to reformat my ext2 USB HD

Short question: Is it possible to configure Windows 7 Pro and/or Windows Server 2012 R2 such that when you plug in a USB disk formatted with ext2, it does NOT suggest to the user that it's corrupted or needs formatting with a Windows native format? I.e. it just either doesn't say anything, or mounts it with ext2fsd or something?

Background:

I have a Linux VM that I want to back up to a USB drive. I have an rsync script that I used to use when the same Linux was on bare metal, to make rotating incremental backups to the USB drive's ext2 filesystem. Now that it's a VM, I have to be able to get at the drive differently, because the VM host is Windows Server 2012 R2.

I have two options for where to plug the USB drive in: the server, or the boss's desktop (Windows 7 Pro.) Both ways I envision using rsync on cygwin where it's plugged in.
