How to change memory allocation for WSA on Windows 11

On Windows 11, you can now configure the amount of memory to assign for the Windows Subsystem for Android (WSA), and in the guide, you will learn how. In the past, WSA managed memory usage automatically. However, starting with version 2304.40000.5.0, Microsoft added a new option allowing you to specify the amount of memory to allocate to run Android apps.

The new feature will prevent the subsystem from affecting the main system performance on devices without a significant amount of memory or anyone who wants to restrict the memory usage of WSA.

This guide will teach you the steps to change the memory allocation for WSA on Windows 11.
