Build Windows images with Packer using WinRM communicator and PowerShell provisioners. Use when creating Windows AMIs, Azure images, or VMware templates.
The same skill content is published under more than one repo. The install counts are split across them; any of these commands works.
Platform-agnostic patterns for building Windows images with Packer.
Reference: Windows Builders
Note: Windows builds incur significant costs and time. Expect 45-120 minutes per build due to Windows Updates. Failed builds may leave resources running - always verify cleanup.
Windows requires WinRM for Packer communication.
