How to Add Compact OS Context Menu in Windows 10


Windows 10 includes tools to help you use less drive space. You can now compress the files for the entire operating system, including your preloaded desktop applications. Compact OS lets you run the operating system from compressed files (similar to WIMBoot in Windows 8.1 Update 1), and single-instancing helps you run your pre-loaded Windows desktop applications in compressed files. The new processes helps maintain a small footprint over time by using individual files, rather than combining them in a WIM file.

Windows 10 can efficiently compress system files. That gives back approximately 1.5GB of storage for 32-bit and 2.6GB of storage for 64-bit Windows.

Compact OS is supported on both UEFI-based and Legacy BIOS-based Windows 10 installations.

For more details about Compact OS in Windows 10, see:

This tutorial will show you how to add a Compact OS desktop context menu for all users in Windows 10.

The Compact OS context menu allows users to quickly query the current Compact state, and allows administrators to quickly compress or uncompress the OS as needed.

You must be signed in as an administrator to add or remove the context menu.
