Microsoft’s latest Windows 10 19H1 (1903) test build is light on new features, and heavy on fixes — which is expected as it rolls toward completion.
Microsoft’s latest Windows 10 19H1 test build, No. 18323, doesn’t include many new features that weren’t in previous test builds. But it’s one of the builds that is paving the way for this release — likely to be designated 1903 — to start rolling out to mainstream uses in April 2019. The new features in Build 18323 are incremental. There’s improved RAW image format support. There are some tweaks and fixes to the new Light Theme coming to Windows 10.
