"I want to change or add some resources to my Amazon Elastic Compute Cloud (Amazon EC2) Windows instance. How do I change the specifications of my instance?Short descriptionYou can change instance types to do the following:Increase or decrease the number of CPU cores.Increase or decrease the amount of RAM.Enable Amazon Elastic Block Store (Amazon EBS) optimization.Enable enhanced networking.Change GPU cores.ResolutionTo resize your EC2 instance, choose an instance type that meets your CPU, RAM, and feature requirements.Consider the following before resizing your EC2 Windows instance:If you launch instances from Amazon Machine Images (AMIs), install the required drivers for the destination instance type. This needs to be done for custom Windows AMIs and Amazon-provided Windows AMIs created before August 2018. Status checks fail if the instance doesn't have the required drivers.For instances created from AMIs after August 2018 install or upgrade the  required drivers for the destination instance type.Verify that your current instance type is  compatible with the new instance type that you choose.If the current instance has an  instance store volume, any data on the instance store volume is lost when the instance is stopped. Be sure to  back up the data on your instance before you stop the instance.If you're not using an  Elastic IP address, the public IP address is released when you stop the instance.It's a best practice to maintain backups of your instances and data. Consider creating an AMI or  creating snapshots of your EBS volumes before you change the instance type.If your instance is part of an Auto Scaling group,  change the launch configuration to launch the new instance type. On the Copy Launch Configuration page, choose the new instance type.Related informationStatus checks for your instancesTroubleshoot instance launch issuesHow do I move my EC2 instance to another subnet, Availability Zone, or VPCCreating a launch configurationModify the supported instance types (Change instance types on the same Dedicated Host)Follow"
