Microsoft releases two new Windows 10 previews ahead of October 2018 Update

Microsoft today released two new Windows 10 previews for PCs. The first build is from the RS5 branch, which represents the Windows 10 update the company plans to release next month, and the second is from the 19H1 branch, which, as its name indicates, will arrive in the first half of next year.

This year, Microsoft has released two new builds on the same day more frequently than ever before (the last time was in July). The company is simply more comfortable developing two major Windows 10 updates at once.
