How to self terminate EC2 from powershell?

I need powershell code to terminate an instance without hardcoding the instance ID.

I tried 

aws ec2 terminate-instances --instance-ids 'curl http://169.254.169.254/latest/meta-data/instance-id'

But the instance doesn't terminate. Any ideas?

As mentioned in the comments, I suggest working with AWS Powershell Module.

The following code terminate an instance based on ID and Region.

Install-Module AWSPowerShell
Import-Module AWSPowerShell
#Set AWS Credential        
Set-AWSCredential -AccessKey "AccessKey" -SecretKey "SecretKey"     
#Remove EC2 Insatnace
Remove-EC2Instance -InstanceId "InstanceId" -Region "Region"  -Force

How to create new AccessKey and SecretKey - Managing Access Keys for Your AWS Account.

AWSPowerShell Module installation.

From the docs:

Terminates a stopped or running Amazon EC2 instance, prompting for confirmation before proceeding.

Note that terminated instances will remain visible after termination (for approximately one hour). The Terminate operation is idempotent; if you terminate an instance more than once, each call will succeed.

In my case, I was able to set this attribute at instance launch (using some python code in the lambda that launches the instance) InstanceInitiatedShutdownBehavior='terminate'

then in powershell simply

shutdown /s /t 0

If InstanceInitiatedShutdownBehavior='terminate' is not set, then I believe the default is to stop (as opposed to terminate)
