With the launch of Windows 10 only a month away, Microsoft's campaign is in full swing and the company is allowing fans to enjoy early beta copies release to test its operating system themselves. While all is well at least regarding the promotion of the upcoming operating system, the company has recently made some confusing statements about Windows 10.

Unlike the company's earlier announcement, not everyone will be receiving the free Windows 10 upgrade, not even those who have the beta copies.

Recent reports claim that PCs on Window 7 or Windows 8.1 can be upgraded to Windows 10. Microsoft's Head of Operating Systems, Gabe Aul had himself said earlier that developers who acquired the beta copy or "Windows Insiders" would receive the final and active build of Windows 10. Aul recently wrote on his blog:

"Windows Insiders running the Windows 10 Insider Preview (Home and Pro editions) with their registered MSA connected to their PC will receive the final release build of Windows 10 starting on July 29th. This will come as just another flight. I've gotten a lot of questions from Windows Insiders about how this will work if they clean installed from ISO. As long as you are running an Insider Preview build and connected with the MSA you used to register, you will receive the Windows 10 final release build and remain activated. Once you have successfully installed this build and activated, you will also be able to clean install on that PC from final media if you want to start over fresh."

The post has been edited recently, taking away the "and remain activated" portion, suggesting that users of Windows Insider won't be getting a genuine copy after all.

Aul has also added that the free update for Windows 7 or Windows 8.1 will be only for users who have installed genuine Windows software and they would be eligible for the upgrade within one year of the release of Windows 10.

Windows 10 will be available to the public on July 29.
