Windows 10 is coming and will arrive as a free upgrade to computers and tablets on July 29, CNet reports. 

Most users who have purchased a computer within the last five to six years will be able to upgrade to Windows 10 for free. These users are likely to be running Windows 7 or Windows 8. Tablet users are probably using Windows 8.1.

Microsoft's Windows is the operating system that operates most personal computers and helps businesses run as well. Even though Windows is dominant in the operating system world, critics have said that Microsoft products are in decline as newer products, such as mobile phones and cheap software, emerge. Microsoft wants to improve its image after Windows 8 received a great deal of negative feedback and convince users to install Windows 10.

Microsoft has been mostly silent on a release date for Windows 10, even during its developer conference in April. Some industry experts became concerned that Windows 10 would not be ready in time for the summer.

Those who are not eligible for the free upgrade to Windows 10 will have to wait until retailers start selling individual licenses or start pre-loading new PCs with the software. A leak from Newegg over the weekend detailed that PC makers would receive the software Aug. 31. The leak further revealed that the cost of the software would be $109, and the Professional version would cost $149. ZDnet was the first to spot the screenshots for the prices of Windows 10. 

Arriving in the new Windows 10 will be a new and improved Start button.

Windows users groaned when Windows 8 took away the popular button. Windows 8 also had a tablet-focused interface that did not excite most users. A new browser called Edge is coming to Windows 10, replacing Internet Explorer. Finally, Microsoft's digital voice assistant Cortana will be updated.

Windows 10 wants to be the operating system that can be used on any device, providing a seamless transition from each device.
