MS has revealed (http://blogs.windows.com/bloggingwindows/2015/03/16/how-windows-10-achieves-its-compact-footprint/) that:

• W10 will take up to 6.6 GB less space
• Reinstall faster
• Will be easier to rid of crapware
• To achieve this will use “Wimboot” to decrease system file and app sizes

To check if it can be used, the OS will check the RAM and other parameters of your machine before installation. To accomplish this, the files needed for recovery from failure will be stored on a disk you create, which will enable recovery from “severe corruption”.

“Also, when you "refresh and reset" Windows 10, it'll tap existing runtime system files, bringing your system to the same point you started at without the need to download. Microsoft said that "we are also redesigning Windows' refresh and reset functionalities to no longer use a separate recovery image (often preinstalled by manufacturers today) in order to bring Windows devices back to a pristine state." By "pristine state" Microsoft might mean "bloatware-free" -- in other words, users can quickly "refresh and reset" unwanted apps out of a new machine as soon as they buy it. Again, that's normally a time-consuming mess that sucks a lot of the fun out of owning a new computer. And thanks to the Lenovo Superfish fiasco, that's the first thing a lot of folks now do after buying a new PC.” – Engadget

Now? Just get rid of the “hard coding” so we can customize the hell out of it!
