Upgrading my office computer to Windows 10. The best Windows to date. If you are using Windows 7, then it is not so much urge for you to upgrade. However, for Windows 8 and Windows 8.1, which I find really clumsy to use, then Windows 10 is a must. You get both Windows 7 and Windows 8 interface in Windows 10. Not revolutionary, more like a fix for Windows 8.
Microsoft is pushing out Windows 10 for free to those genuine Windows 7 and Windows 8 users. Yes, FREE upgrade. No need to pay.
