Download Windows 10 Preview Builds for Update

Microsoft Insider program enables users to download and install Windows 10 Technical Preview and frequently released rebuilds free. This Windows 10 guide shows how to update and download Windows 10 Preview builds from your Windows 10 PC.

Following screenshots are from my Windows 10 installation on VMware Player. When Windows 10 was first available for public trial, I did download Windows 10 and using VMware Player, I had installed the first Windows 10 Preview free trial version as a virtual PC. Then following the below steps, I upgraded Win10 to latest preview build.

Before you start installing new Windows 10 Technical Preview builds, please note that your PC will require at least 2 GB of RAM.
Otherwise update wizard will exit with "Couldn't install Windows 10 Technical Preview" error.
Or "Failed to install the new preview build, please try again later. 0xC1900200"

Click on Preview builds selection.

When the new wizard screen is displayed, you will see the "Download now" button which enables Windows 10 users to download new preview build if available. Press on Download button to continue.

Then the wizard will be checking for new Windows 10 preview build and downloading it if released for Windows Insider participants.

Please note that the installation of the new build of Windows 10 Technical Preview may take some time. And after the download and setup of new Windows 10 rebuild is completed, you have to reboot your PC (or if you install Windows 10 on virtual PC, you have to restart it).

Then your Windows 10 PC updated with most recent Windows 10 Tecnical Preview edition will require a restart to complete installation. Unfortunately, the configuration after restart takes considerable time before the logon screen is displayed.
