In the last step before its official rollout to the public on August 2, Microsoft has begun delivering Windows 10 version 1607 to the Release Preview branch of the Windows Insider program.
The Windows Insider Release Preview branch is getting Windows 10 version 1607 a few days early.
The countdown clock to the public release of Windows 10 version 1607, aka the Anniversary Update, is down to just days.
In preparation for that big reveal on Tuesday, August 2, Microsoft last night began delivering the build a few days early to anyone who had signed up for the Windows Insider program and chose the ultra-cautious Release Preview option instead of the Fast or Slow rings.
On the one test system that I had configured for this branch, the upgrade process started shortly after 6PM Redmond time. The upgrade process itself took about 30 minutes, and the machine in question now shows Version 1607, build 14393.5, on the About screen.
This major Windows 10 upgrade starts its general rollout on August 2.
If you're eager to jump to the front of the line, there's still time to enroll your activated Windows 10 PC in the Insider program. You must be running Windows 10 and be signed in with a Microsoft account...
