Update to the latest build of Windows 10 Technical Preview, because old builds are set to auto-expire and they don’t boot

Microsoft has apparently set up the builds of Windows Technical Preview, to automatically expire after a certain time.

The news broke through at the Microsoft forums, when a user posted that he had been getting messages on his PC, that his Windows 10 is about to expire.

He questioned what would happen once the Windows build expires.

A Microsoft support engineer, replied saying that users will get a warning message, about 2 weeks before a build expires. The message warns that the build is about to expire, and suggests the user to update to the latest build.

After the build’s license expires, the system will reboot automatically every three hours. And that’s not the worst part.
About two weeks after the build expires, the system will not boot at all. The PC will be bricked.

So, the 2014 builds 9841, 9860 and 9879 expired on April 15th, and will stop booting from the 30th of April. And the 2015 builds 9926,10041, and 10049 will stop working on October 15th.

Here is a table which shows timeline in which the Windows Builds will expire:

“My build expired, and my PC won’t boot. How do I update Windows 10 Technical Preview?”

The solution is simple, yet slightly complicated, in that you will need a second PC, to download the latest ISO of Windows 10. You will need to use the ISO to create a bootable USB or DVD and then use the disk to boot the bricked system.

And this move isn’t some sneaky thing from Microsoft. PC World notes that, back when it launched Windows 10 last year, Microsoft warned users clearly that the builds would expire on 15th April.

There could be two reasons why Microsoft is doing this. Firstly, this method will encourage users to install the latest build of Windows 10. This is absolutely essential, as the latest versions will have fixed bugs found on previous builds.

Secondly, this is also essential to prevent the operating system from being pirated. Windows 10 is offered as a free update for Windows 7 and 8 users already, what more can we expect?

The Windows 10 RTM (release to manufacturing), is scheduled for release in June 2015. It’s less than two months away.

Microsoft is already working on the next Windows update, which is codenamed as Windows Redstone, and is slated for a release in June 2016. It will reportedly bring in features that have been cut away from the RTM.

A couple of weeks ago, Microsoft released an optional Windows Update for Windows 7 and 8. It is actually a silent installer, which installs a Windows 10 downloader. This will automatically update the PC to Windows 10, when it is released.

Personally I’m still using Windows 10 Build 10041, and will update it only to a future build, probably¬† to the RTM. As my PC is working perfectly fine, I don’t see a point to download a 4GB ISO and update to Windows 10049, which will expire on the same day as 10041.
