How to update to Windows 10 Pro Technical Preview

In my previous post, I have shown you that my old Compaq Presario CQ42 was running Windows 10 Technical Preview (Build 9841). Most of apps are running well though lots of bugs are there since it is a technical preview operating system.

Just two days ago, on 23 Jan 2015, Microsoft released a new build of Windows 10 Pro Technical Preview. The build number is 9926. It comes with the new Cortana integration on desktop, tweaks to Start menu and user interface, a new XBox app and more. Looks interesting features to try.

Since I already have Windows 10 Tech Preview build 9841 installed on my laptop, it is very easy to update to the latest build. This post is intended to show you how to update Windows 10 Tech Preview build 9841 to Windows 10 Pro Technical Preview build 9926.

If you have not installed the Windows 10 Tech Preview before, then you need to download Windows 10 Technical Preview ISO file from Microsoft website. Then you need to create a bootable USB flash drive to boot it to your PC / laptop.

1. Click the Start menu, then search for ‘windows update settings’.
