I have the W10 tech preview build 10130 installed on my Dell M3800 Precision laptop which previously had Windows 7 & 8 installed on it. How can I upgrade from the preview to the full release?

Not sure why you are not already updated to a newer build. Is Windows Updates ok? are you not being offered new builds?

Do you mean upgrade to Windows 10 and leave the Insiders Program?

Or just get a newer build?

The fastest way to get the upgrade is to download the ISO.  An ISO is like a dvd so to use it you will need to right click>mount.  Start the upgrade from within windows.
WARNING:  DO NOT USE THESE TO DO A CLEAN INSTALL (until after you have already updated).  If you do you will not be able to activate it unless you have previously upgraded to win 10 and activated it.  You then will be forced to re-install your previous OS before upgrading to win 10

The Official Final Windows 10 download is now available Use the download tool to create ISO media to update your windows. http://www.microsoft.com/en-us/software-download/windows10 Use Download Tool Now (32bit version) http://go.microsoft.com/fwlink/?LinkId=616935 Use Download Tool Now (64bit version) http://go.microsoft.com/fwlink/?LinkId=616936

Thanks for the reply, but I'm a little confused. Are you saying I need to install Windows 7 or 8 and then use the ISO you linked to to upgrade to Windows 10?

Is there any way to activate the tech preview I'm running so that I don't have to do a clean install?

Thanks.

I'd preferably like to switch to the mainstream W10 builds (leave the insider's program), but at the very least want to get up-to-date on the tech preview. 

A while back Windows Update showed a new preview build, but when I tried installing it several times it always got stuck at 71%. Now Windows Update does not show any updates.

Hi,

I recommend to clean your computer first, and try to upgrade again:

1. clear Update folder: C:\Windows\SoftwareDistribution

2. If you get any security application installed on your computer, temporarily remove it since it will sometimes block the update.

3. Run following commands to scan system files:

Dism /Online /Cleanup-Image /RestoreHealth

SFC /scannow

rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN

Then try to update again.

If still fail, get back to your previous Windows 7, and try the media creation tool:
