The news comes days after the company finally started making the installation files for Windows 8.1 available for download to the masses for free to easily recover when reinstallation of the operating system is needed and you don’t have the recovery discs. The only catch to download the Windows 10 preview ISO is that you’ll to have wait a little longer, because Microsoft will only make an ISO of Windows 10 available for download through the Windows Insider Program in the Slow ring. Today’s build 9879 has been released to the Fast ring of the Windows Insider Program, which means that there isn’t a new ISO to download. Here is the Microsoft statement: This is a good news, starting with Windows Technical Preview build 9879 means that you won’t have to resource to workarounds to install the operating system on your Surface Pro 3 using the VHDX method. Update: If you can’t wait for Microsoft to release the ISO version of the operating system, you can download the enterprise version of build 9879 now.
