Microsoft is rolling out a new cumulative update for Windows Insiders on Release Preview Ring. The latest update bumps the Windows 10 version to 10.0.17763.349.
The build is supposed to come with just bug fixes and performance improvements for those who are running on Windows 10 Release Preview. Microsoft hasn’t released an official changelog for the update yet so we can assume that the update has just fixes and performance improvements. That said, it’s not advised to skip Windows Updates so make sure you download them at the earliest.
Windows 10 should automatically download and install the cumulative update but if in case you want to speed things you can head to Settings>Update and Security and Check for Updates to download and install updates manually.
