Windows 10 was hailed by many as a return to form for Microsoft after Windows 8 failed to impress. The menu is back in Windows 10 and the design of this operating system takes the best features from Windows 7 and Windows 8 to form an operating system that does a better job of bridging the gap between PCs and tablets than Windows 8 attempted. Windows 10 Professional has a similar look to the Home version but has many additional features that are geared toward businesses. Note that this is a license for the 64-bit version of Windows Professional and must only be installed on 64-bit machines. The operating system will not work on 32-bit PCs so please check your system specifications before purchase. Orders are fulfilled with 1 hour during normal business hours. You will receive one license activation code and a link to Microsoft’s Media Creation Tool for Windows 10 Professional after purchase.
