I noticed that I could no longer use SSH to git clone, push, etc in the Windows CMD prompt.
You may be getting these errors:
Error connecting to agent: No such file or directorypermission denied (publickey)
It turns out that setting a HOME environment variable will mess up the OpenSSH commands; probably because it can't find the .ssh directory(C:\Users\my_user\.ssh).
The solution is just to remove the HOME environment variable.
The reason I had this set in the first place, was that I was playing around with nvm and the nvm command will complain about no HOME being set when it tries to download builds.
