Has it really been that long since the first Windows 10 Technical Preview went live? Sure enough: Builds 9841, 9860, and 9879 all expire on April 15, 2015, and will quit booting when the clock ticks over to April 30, 2015, in just over two weeks. Here’s the blurb from the Windows 10 Insider Hub that tells the story, with a warning worth heeding:
Please note what happens if you procrastinate past the “freshness date!”
The current build for Windows 10 is available through Windows Update in the Settings app, and also through a link in the aforementioned update in the Insider Hub app as well. If you are trailing behind on any Windows 10 builds, you’ll want to make sure to catch up before April 30 rolls around, because you’ll be forced to do a bare metal clean install of some OS (Windows 10 current build or otherwise) just to get your machine to boot. You’ve been warned!
And you thought “Tax Day” was just about punishment from the IRS.
