The last (good) OS Version

Easy Installation (especially with an SSD used to support the OS), and I think the last correct version of Windows ... until version 9?
The Home Premium version is full featured and more than enough for use at home and for small organizations (associations, artisans, small businesses ...) that have not developed a network tree administered servers.

Warning reminder for those wishing to buy a box = This is the OEM licensed version allows installation on a single machine and you must purchase a new license if you ever profoundly change your config (motherboard for example, but not the RAM or discs), or if you have multiple machines to equip OS.
