This feature allows users to run 16-bit applications on 32-bit computers. However, the feature is not available on Windows 11 and other 64-bit versions like Windows RT and Windows 10 IoT Core.

The 64-bit version also runs 32-bit apps, and there are many in existence. However, people still run old 16-bit DOS and 16-bit Windows apps that only 32-bit Windows supports.

Google announced in December 2017 that 32-bit apps would eventually be phased out on 64-bit devices, and now the company has provided specific dates for the process.
