To log into the EC2 instance from a Windows OS, follow below sections:
1) (This step is only required if your key pair is saved as .pem format) “Convert your private key using PuTTYgen” section under these instructions.
2) “Connect to your Linux instance” section under these instructions.
Use ec2-user for my-instance-user-name in the instructions.
If you plan on not using Putty on Windows, and instead will be using a Linux emulator or other commandline utility on Windows, please follow the commandline instructions and ensure to use the appropriate convention for the file separator (”\” in Windows, “/” in Unix) in the full path to the private key file based on the commandline utility you chose.
