Setting up terminal for course v3 on Windows 7

I’ve been following the v2 course using AWS EC2 for instances, but see that v3 has begun. I’d like to save some dough by switching to Google Cloud (with $300 credit!). For AWS, I’ve been using Git for
Windows on a Win7 PC as my terminal, with success, but I see that Cygwin seems to be recommended. Before I painstakingly set things up for v2 I tried installing Cygwin on my machine, but ran into a nightmare of conflicts, I figure due to the previous installation of Git for Windows. Can I avoid installing Cygwin again to use GCP? Appreciate any suggestions.
