History
It was introduced in Windows Vista on the setup disc only but in Windows 7 it is installed by default onto the HDD under the boot option “Repair your computer” Windows 8 build 8102 gave the interface a huge redesign, bringing a metro interface to it. In Windows 10, an option was added to go back to the previous build.
