How many times has this happened to you? You’re forced to “refresh” Windows with a clean install—and then you wait, and wait, and wait
while numerous updates download, install, and bring your PC up to date.
Good news, according to Microsoft—that nightmare is over.
Microsoft said Monday that Windows 10's installation process will offer improvements over Windows 8 in two ways: If the PC can support it, Windows 10 installs in a compressed state, saving a small but important amount of disk space. And even more significantly, if you do
need to reinstall, Windows 10 recovers using runtime system files that builds the new operating system from files that are already in place. And you can create your own recovery disk!
