Microsoft today released a cumulative update for Windows 10 PCs that are running build 14393 in the Fast ring. KB3176925 brings the build number to 14393.3.
We're less than two weeks away from the Anniversary Update now, so with today's update, it's becoming clear that build 14393 is the RTM build, meaning that it's the build that non-Insiders will get on August 2.
Insider Preview build 14393 was released to the Fast ring for PC and Mobile four days ago. It contained a few fixes, but most importantly, the only known issue (for PCs) was a driver issue for Surface Pro 4 and Book, which could be - and was - patched through Windows Update. Two days later, it was released to the Slow ring.
Interestingly, there is no Windows 10 Mobile cumulative update to coincide with the PC build. Also, there is no changelog for build 14393.3 just yet, but when there is, it will be available right here.
Of course, we'll keep you updated as events unfold, so make sure to check back.
Update: Build 14393.3 is now available for Windows 10 Mobile as well, but only to the Fast ring.
Update: The changelog is now available.
