Windows 10 Technical Preview 64-bit

Microsoft’s upcoming OS Windows 10 is under development and testing and a free Technical Preview build is available for download to public. This Preview build can be installed and used as a primary operating system but you may face bugs and issues as its a testing build.

Microsoft has released offline ISO files of Windows 10 Technical Preview build 9926 to public. The ISO files are available in both 32-bit (x86) as well as 64-bit (x64) editions.

Click one of the Download links on this page to download a special file—it’s called an ISO file—that you can use to install the preview. When the download is complete, transfer the ISO file to installation media such as a USB flash drive or DVD. Double-tap or double-click setup.exe from the installation media, and then follow the steps.

For both 32-bit & 64-bit Microsoft provided the same product key, so during installation when OS requests to enter a product then apply below 25-character product key without any mistakes. Windows 10 Product Key : NKJFK-GPHP7-G8C3J-P6JXR-HQRJR
