Make sure you have putty installed on windows.
Configure Windows Environment Variable
- Type Environment into your Windows 10 search bar. Otherwise, open up System Properties / Advanced System Settings and find your Environment Variables.
- Add a new System variable
- Variable Name: GIT_SSH
- Variable Value: full path to plink.exe file (you may also have pageant.exe and puttygen.exe in the same folder).
- Mine was: C:\Program Files (x86)\PuTTYputty\plink.exe
- Also note, System Variables in windows will need a restart, where as User Variables just require you to log on and off again
