This processor type does not support this installation package. What is the error 0x80070661?

Error 0x80070661 is related to the Windows Subsystem for Linux application, which allows you to run other operating systems in Windows without the need for a virtual machine. While you can download it from the Microsoft Store, it requires additional components to run.
