Windows 10’s next update is the April 2019 Update, which is version 1903 and was codenamed 19H1 during development. It features a light theme, speed improvements, and lots of polish. There are no crazy new features like My People or Timeline.

This article includes everything new as of Insider Preview build 18323, released on January 24, 2019.

The news of Spectre shook the industry at the start of 2018. Spectre is a design flaw in CPUs, and it allows programs to escape their restrictions and read other programs’ memory spaces. Microsoft patched Windows to help block Spectre attacks, but the resulting patches reduced your PC’s performance in some scenarios—especially on PCs from 2015 and earlier, which don’t have the CPU features needed to speed up the fix.

Now, a change in the April 2019 Update looks set to practically eliminate those performance penalties and speed your PC back up. Specifically, Microsoft is enabling “retpoline” and “import optimization.” All you need to know is your PC should get faster, and you won’t even need to think about it. But here’s a detailed document from Microsoft explaining how these optimizations work if you’re interested in the details.
