Microsoft has released, and then rapidly edited, some information about the incoming Windows 10 release and the mechanisms through which its customers will get the upgrade for free on release day.
The blog, from regular Windows 10 spokesperson, Gabriel Aul, informs users about the circumstances in which the update is free and automatic. Users have complained that it is complicated and confusing and that where once Microsoft suggested a free for all, the offer is actually only a free for some.
At first read it appeared that anyone with a Microsoft Account, or MSA, and Windows 10 Insider Preview, both home and professional versions, would get the upgrade gratis on 29 July.
"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," said Aul. "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."
Later though, this statement was edited and it now presents a different offer, a space where the word ‘activated' used to be, and some additional information.
"Once you have successfully installed this build, you will also be able to clean install on that PC from final media if you want to start over fresh," says the updated blog.
"It's important to note that only people running Genuine Windows 7 or Windows 8.1 can upgrade to Windows 10 as part of the free upgrade offer."
Gaul addressed questions about the changes on Twitter, explaining that the information had led to a number of questions from Microsoft customers.
Microsoft is currently putting the finishing touches to its Windows 10 platform and the preview versions of both Windows 10 for x86 PCs and Windows 10 Mobile for phones and small tablets.
The software giant confirmed earlier this month that Windows 10 for the PC will be available from 29 July, but the firm continues to push out updated versions to testers on the Windows Insider programme.
Meanwhile, Microsoft has yet to disclose a release date for Windows 10 Mobile, other than saying it will come later this year.
Build 10130 for PCs was released to those on the cutting edge fast ring at the end of May, but has now been deemed stable enough for release to those who prefer to be on the slow ring.
"We are releasing Build 10130 of the Windows 10 Insider Preview to Windows Insiders in the slow ring," said Aul who is Microsoft's director of programme management for the Windows Fundamentals team, in the Windows blog.
"This build has been in use by Windows Insiders in the fast ring since 29 May and has proven to be stable enough to publish for Insiders in the slow ring along with a few fixes."
The updates include fixes for problems such as the loss of audio playback that some testers experienced after installing Build 10130.
But Microsoft warned that there is a known problem with the company's Surface 3 tablet that prevents the Windows 10 Insider Preview from installing. The firm is recommending that users of this device do not install it until a fix is available.
The updated version for phones, Windows 10 Mobile preview Build 10136, was made available on 16 June for testers on the Windows Insider programme who have opted to receive updates via the Fast ring.
It offers numerous fixes and refinements such as improvements to Cortana and the user interface, including changes that make a Windows Phone with a larger screen easier to use one-handed.
This will not be released with the Windows 10 version for PCs at the end of July, but is set to come later in the year and will likely depend on when the mobile networks and handset vendors are ready to support it.
In the meantime, users of Windows 7 and Windows 8.1 have already started to see a notification tool on the desktop designed to let them know when Windows 10 is available and allow them take advantage of the free upgrade Microsoft is offering.
However, Microsoft has also warned that some features will no longer be supported in Windows 10, including Windows Media Centre and DVD playback, so users will have to install a third-party app to play DVDs.
