INFO: Using Windows Image Boot (WIMBoot) to reduce OS disk footprint

Interested in saving 5GB of disk storage on the system drive after installing Windows 8.1 Update 1?

Now that Windows 8.1 Update has been released, we want to talk about a new way that Windows 8.1 can be installed on Windows 8 logo-certified devices (since UEFI is a requirement) with smaller disks, e.g. devices with 16GB or 32GB SSDs or eMMC storage, while still ensuring that there is plenty of storage left for apps and data.

This new deployment option, called Windows Image Boot (or WIMBoot), takes a different approach than traditional Windows installations. Instead of extracting all the individual Windows files from an image (WIM) file, they remain compressed in the WIM. But from the user’s perspective, nothing looks any different: You still see a C: volume containing Windows, your apps, and all of your data.

This is supported with all SKUs of Windows 8.1, with the Windows 8.1 Update. (Remember, we’re not talking about a different version of Windows, just a different way of installing it.)
