I'm trying to figure out if I can SSH into an AWS EC2 instance that's running Windows RDP. I've been given a username and password for it. I understand how to SSH into Linux EC2 instances using a .pem file. Is there a way to SSH into this Windows instance using the credentials I've been provided?

This is more about Windows than AWS specifics. Starting with Windows Server 2019, OpenSSH is installed by default, but it won't be listening right away. You need to log in via RDP or some other desktop method at least once to enable it. After that, make sure the OpenSSH server is running and that your security group allows traffic on port 22 from where you’re connecting.
If port 22 is open in your EC2 security group and you're still seeing a timeout, it might be due to the Windows firewall. You should check if the OpenSSH inbound rule is enabled and confirm it's actively listening with a command like netstat -an | findstr :22.
