As reported earlier, interested users can already get their hands on version 1903, but these cumulative updates will certainly help with performance and stability. > Microsoft was originally expected to deliver this latest Windows 10 feature update last month, but it pushed the public release to May to iron out any last-minute bugs. Hopefully today’s quality update will help speed up the process.
