Microsoft is pushing out new Windows 10 Preview Builds with somewhat alarming rapidity recently. Alarming, because it seems my test PC is always either downloading one of the massive updates, or installing one.

My test PC is now running Build 14379, and I haven’t noticed any changes of interest, good or bad. Let’s look at the release notes to see what’s different in the new builds.

Build 14371

A new Activation Troubleshooter helps to resolve problems encountered by users after changing hardware such as hard drives and motherboards.

This build also includes improvements to accessibility, and easier to understand Edge download displays. Some tweaks were made to a few display settings, and more display settings will now be maintained between builds.

Build 14372

According to the release notes, Build 14372 has “a handful of fixes to [improve] overall performance and reliability.”

Build 14376

Performance and reliability fixes for Windows Store, various display fixes, a fix for a specific Edge/Explorer crash, and a fix for an authentication error related to Terminal Services.
