Microsoft is finally fixing a few of the most hated things about Windows. In a blog post, the software giant revealed that compared to Windows 8.1, Windows 10 will take up as much as 6.6GB less space, will re-install faster and possibly be easier to rid of crapware. To achieve those goals, Microsoft is using "Wimboot" disk compression to reduce system file and app sizes. To make sure it doesn't compromise performance, the OS will check your system RAM and other parameters before installing it. Also, instead of being stuck with files needed to recover from a failure, you'll create your own to backup and restore the OS and apps on PCs and tablets (Windows phones already have this feature). It added that the new technique will still allow recovery from "severe corruption."
