The last ‘preview’ build of Windows 10 released to Windows Insiders was build 10166, so it’s been quite a while since Insiders received a build to test. Since then, Windows 10 RTM’d and was released to the public, meaning the company is now hard at work on Windows 10’s first non-patch update coming in October. Today, Microsoft has released the first Insider build for the first update for Windows 10, build 10525.
Build 10525 is now available for download via Windows Update for Insiders who have registered to be apart of the program. The build will be delivered much like any normal build, and is coming from the “th2_release” development branch much like 10512 did for mobile Insiders. If you’re yet to see the build appear in Windows Update, give it time as the update is rolling out in waves.
Microsoft’s first non-patch update for Windows 10 will focus on under-the-hood improvements mostly, whilst introducing a number of much needed features such as extensions for Edge and a universal messaging app. Build 1052x marks the first build Insiders will get for testing, and over time more of these features will show up.Further reading: Windows 10
