First of all, Windows 10 will be able to run android apps natively! How cool is that?
Windows 10 will be released on July 29, 2015. Microsoft is already advertising it to Windows 7 and 8.1 users using a system tray pop-up. This is a free upgrade, and will probably be a good one for Windows 7 and 8 users alike.
Microsoft wants to get all recent Windows machines on the same operating system, providing a standardized Windows platform and pushing the “universal apps” offered by the Windows Store. After the mess of Windows 8, Windows 10 is looking pretty good.
Yes, It’s Free (For Most People)
Windows 10 will be a free upgrade, assuming your computer runs Windows 7 Service Pack 1 or Windows 8.1. As long as you upgrade to Windows 10 within the first year, you won’t have to pay a cent. Despite some confusion online, you won’t have to pay anything. As long as you upgrade to Windows 10 within the first year, you can continue using Windows 10 and getting updates for the “supported lifetime of the device.” It’s a full copy that will continue to work.
If you have an older computer running Windows Vista or a previous version of Windows, you won’t get a free upgrade. You may want to buy a new computer if you have such an old computer, anyway. If you have a pirated (“non-genuine“) copy of Windows, you may be able to upgrade — but you’ll continue to have a “non-genuine” copy of Windows 10.
