Microsoft Releases Windows 10 Insider Preview Build 17672

Living with S Mode: Apps

Windows Insiders in the Fast ring and Skip Ahead have a new build, 17672, to install today. Unlike with recent builds, however, there isn’t much new in this one.

In fact, there’s only one semi-major change: The Windows Security app has been updated to require antivirus products to run as a protected process to register within the app.

“Products that have not yet implemented this will not appear in the Windows Security UI,” Microsoft’s Dona Sarkar notes, “and Windows Defender Antivirus will remain enabled side-by-side with these products.”

Dona also explains that you can disable this new behavior by creating the following registry key and rebooting:

HKLM\SOFTWARE\Microsoft\Security Center\Feature DisableAvCheck (DWORD) = 1

This key will be removed as Windows 10 Redstone 5 gets closer to release.

Check out the original blog post for more information about known issues and other small changes in this build.

    As before, just try and be patient as the Online portion of the install can take awhile, as in hours, before the first reboot is reached.

      In reply to Dan1986ist:

      I noticed that if a Windows defender update is present, or any other update, it can take hours for the Insider build to install.

      The work around that works for me: Let any other update install, then reboot, then install the Insider build. This way the Insider build installs without a hitch on my side.

      Good luck!

    I am curious to find out of the dark themed file explorer have been more refined, as last week, MS noted that the latest internal builds had more polished dark theme than last week's insider build.

    I can't get this build nor the previous build 17666.1000 to install on my new Surface Pro. I keep getting the 'restoring your previous version of windows...' messages after it is attempting to restart and install. It does restore my previous version and I end up opting out of Insider Builds completely, but is anyone else having this problem here? I see this posted all across the internet and everyone says just wait and keep trying, but it has not worked for me. Suggestions?

    The company provides customers to talk with an open mind when you participate in the survey. By this survey, the company can know about their products and services.

    Cannot access Settings, Edge, Store, start menu or any new functionality. Chrome, Teams Office etc. work fine, it seems that the broken area is around web, therefore Edge. Note the first idea i tried was to do the regedt of "Feature DisableAvCheck" but no effect.

    I loaded 17672 and this is first preview build from the beginning of the program that has left my system broken with no path to a working system (back or forward) previously i have always been able to go back.

    Any ideas either of solution or how, without settings, on a surface book 2, to go back to previous build?
