1. What is the Compact OS feature (Compact OS)?

Microsoft started implementing the Footprint reduction process (Footprint is the number of diskspace Windows used for the operating system) operating system on Windows 8 using WIMBoot (Windows Image Boot).

WIMBoot works quite simply, Windows compresses all operating system files into a single file called install.wim and unzip it when needed.

However, WIMBoot has difficulty recovering images.Also WIMBoot has been proven less feasible on Windows versions.

On Windows 10, Microsoft has improved this existing feature and absolutely no need to restore any images.

Since there is no recovery image, in case you reset or refresh (refresh) the system, Windows will recreate itself by using runtime system files (located in / windows / winsxs / directory).

In addition, Microsoft introduced a new or called new feature: Compact OS (OS compression feature) that can store and compress all files in Windows 10.

The advantage of the Compact OS feature is that it is supported by UEFI and BIOS devices.Moreover, to maintain Footprint over time, you can replace or delete Windows version files as needed.

Both WIMBoot and Compact OS can significantly reduce Footprint (Footprint is the number of diskspace Windows used for the operating system) of the operating system.Installing WIMBoot and Compact OS is quite easy and does not take up disk space.

However, unlike WIMBoot, you can enable or disable the Compact OS feature in airplane mode to be easy to configure and deploy.

Note : The Compact OS feature is disabled by default. If your disk space is low, you can enable the Compact OS feature to free up more disk space.
