Windows users, who joined the Windows Insider Program for Windows 10 by Microsoft, will receive the ability to upgrade to the final build version as part of the company's intent. A source reported that Microsoft's current plan will enable testers to download the Windows 10 RTM version once it is available.

Windows 10 Final Build Version Will Be Given To Windows Insider Program Participants

Participating testers of Windows Insider Program for Windows 10 are expected to receive first-hand upgrade ability from preview build to the final version or RTM by 2015. WinBeta claims all participants of the Windows Insider Program will get exclusive access to get the final version of Windows 10 once it is out. It has been confirmed by Gabriel Aul as well via tweet response to an inquiry.

It is not impossible for these participants to receive the final version since the Windows Insider Program allows it. According to the official website of Microsoft, Windows Insider Program provides the following perks to all participants:

1. Getting all the latest Windows preview builds as soon as available.

2. Participants are the first to experience new ideas and concepts applied for Windows 10.

3. All perks are exclusive to those who want to be involved on the program.

As a return, Microsoft is simply asking participants of Windows Insider Program to send feedback and suggestions about the preview builds of Windows 10. Participants can quickly check and download new preview builds to evaluate, explore, experience, test and play around new features and improvements of each build.

However, preview builds are not designed to be installed for computers used on daily basis due to possible bugs, incompatible and other issues that defines early stages of development. Constant updates and changes on the user interface are also expected to happen every now and then as Microsoft continually releases improvements for preview builds.

Windows 10 is expected to be released sometime in late summer or early fall of 2015. It features the return of the Start button, improvements on the multitasking feature and a native engine for multiple desktops.
