Allrighty, then. As per Brandon LeBlanc at the Windows Blog on September 18, Build 19042.508 (KB4571756) likely represents the Version 20H2 final build. He puts it this way “We believe that Build 19042.508 is the final build and still plan on continuing to improve the overall experience of the October 2020 Update on customers’ PCs as part of our normal servicing cadence.”
I’m pretty sure that means it’s the base on which 20H2 will rest, but could see additional incremental updates between now and the official release date. I have to guess that’s a good thing, because there are reports a-plenty that KB4571756 is not problem-free. That is, sources such as Windows Latest and Neowin.net have recited issues with the Windows Subsystem for Linux (WSL), an unwarranted “optional features removal” error message, Start Menu issues, and even an occasional BSOD in the wake of some update attempts with KB4571756.
Want It Now? Sign Up for Release Preview Channel
If the following potential gotchas don’t deter your interest — I have 2 machines running this release without problems, FWIW — simply join the Windows Insider Program, Release Preview Channel. After rebooting your PC you’ll be able to upgrade to 20H2. and see what’s showing in the lead-in graphic for this story with a little artful desktop arrangement. If you want to make this a short-term Insider stay, also click turn the radio button beneath “Stop getting preview builds” from “Off” to “On.” WU will let you default back to 20H2 on a regular, non-Insider basis as soon as that release goes public (probably in mid-October, on or around the 8th of that month).
Should you be worried about the aforementioned gotchas? (That is, WSL broken, the unwanted error message, Start Menu woes, or a BSOD.) Not really. But, just in case you’re among those who might be affected, make an image backup before you apply the update, and you’ll be able to roll back without too much muss or fuss. Kari and I both use Macrium Reflect for that purpose ourselves (the free version is fine for most people), and recommend it to our Win10.Guru readers as well.
