Answer

Hello, The "Get-EC2Instance" cmdlet calls the DescribeInstances API operation\[1].  
  
According to the documentation for the DescribeInstances API:  
"The value is Windows for Windows instances; otherwise blank."\[2]  
  
\[1] https://docs.aws.amazon.com/powershell/latest/reference/  
\[2] https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instances.html

Answer

I would suggest installing the AWS CLI for Windows\[1]. The referenced page provides instructions for installation in Windows.  
  
You could then use the following command:  
  
aws ec2 describe-instances | Select-String "InstanceId","PlatformDetails"  
  
While the Get-EC2Instance only returns a "Platform" parameter, which is blank for non-Windows instances, the "describe-instances" CLI command provides a "PlatformDetails" parameter which will indicate "Linux/UNIX" for instances running a Linux OS.
