Microsoft has already announced July 29 as the release date of the Windows 10 operating system.
The company also said that Windows 7, Windows 8, Windows 8.1 or Windows RT users can get the upcoming operating system for free.
If you don't have any of these operating systems, you may still get a free Windows 10 upgrade.
Windows Vista and Windows XP users will have to pay for Windows 10, and buying the highly anticipated Windows OS may cost up to $199. Many customers, however, may not want to pay this amount.
Microsoft has then outlined a new procedure in a blog post about the Windows 10 upgrade. The blog revealed that people not running Windows operating systems that are eligible for the upcoming upgrade may still get the new operating system for free if they have downloaded the Insider Preview release of Windows 10, current build 10130.
"If you don’t have your Microsoft Account (MSA) connected to your PC, starting in the next build you’ll start seeing notifications asking you to do so. You’ll need to connect the MSA that you registered for the Windows Insider Program with (and accepted the “Microsoft Windows Insider Program Agreement”) in order to continue receiving new Windows 10 Insider Preview builds (both Fast and Slow rings) from Windows Update," Microsoft advised.
The Insider Preview program for Windows 10 will change in the run-up to the release of the first stable version of the operating system.
Currently, all preview builds are automatically opted into the Insider Program. At the official launch of Windows 10, the Insider Program opt-in feature will change. Customers will need to have a registered Microsoft account used for registering in the Insider Program to opt in.
The blog also suggested that it is very unlikely that technical previews, such as builds 10130 and others, will be available forever. Microsoft recommended that interested customers who want to take advantage of the free upgrade should install the Windows 10 Insider Preview at the earliest to avoid expiration.
Windows 10 aims to be better than the existing Windows 8.1 operating system and will bring along many new features to attract customers. Window users who get the upgrade free will not have anything to complain.
