Windows 8.1 Update Installation now only requires 3GB of space
Microsoft has reduced the minimum system requirements of Windows 8.1 with the “Sprint 2014” Update. This means that it requires only 1GB of RAM and 3GB of space. Microsoft launched a new installation mode called Windows Boot Image (WIMBoot), which allows you to deploy the new operating system quickly. This could encourage OEMs to build budget Windows 8.1 devices with smaller disks such as 16GB or 32GB. To be able to access WIMBoot, your device must be Windows 8 logo-certified (requiring UEFI) with SSDs or eMMC storage. The update will be available through Windows Update starting April 8th.
