(Pocket-lint) - If you want to test Windows 11, now is your chance. Microsoft is releasing its first Windows 11 preview build. Windows Insiders can download it - build 22000.51 - right now on their secondary machines. This is an early version just for members of the Insider program. There will be a wider public beta in the summer. While anyone can become a Windows Insider and download the preview, you should only install it on a system that you don't rely on, because it likely contains bugs and could break things. You can sign up for the Microsoft Insider program here. Once you enroll, navigate to Settings > Update & Security > Windows Insider Program on a Windows 10 device to enable the Dev Channel and get it. You’ll need a compatible PC. Use Microsoft’s PC Health Check app to see if your system is supported.
