What’s new in Windows 10 build 10049, list of changes

Windows 10 Technical Preview (build 10049) is now rolling out to all those Windows Insiders in the Fast ring of updates. As most you probably noticed, Microsoft is not releasing ISO files until it releases the build into the Slow ring.

Delivering on the promise of more frequent releases, Microsoft is releasing build 10049 only several days after Windows 10 build 10041. The new build includes a few fixes, but you won’t see many significant changes. Perhaps the most important inclusion in this build is Project Spartan, as the company is including an early preview of its Internet Explorer replacement.
