Microsoft today rolled out cumulative update KB4058258 for Windows 10 Fall Creators Update and bumps version 1709 to Build 16299.214.

Microsoft today rolled out cumulative update KB4058258 for Windows 10 Fall Creators Update (Version 1709). This new update will bump your build up to 16299.214. There are no new features in this update, but it does include bug fixes and security improvements. This is the company’s third update since this month’s Patch Tuesday which introduced issues with patches for the Spectre and Meltdown vulnerabilities. This fixes problems that left AMD devices unbootable.

Windows 10 Build 16299.214 for Fall Creators Update

The update includes bug fixes and quality improvements for Fall Creators Update, but no new features, as is usually the case with cumulative updates. Here is a look at what’s included in this latest build. Note that there are a few known issues with this build, too. You can get a full rundown at Microsoft’s Support Page:

  • Addresses a compatibility issue where colors are distorted when the system is connected to displays that support wide color gamut.
  • Addresses a condition where a second monitor that is connected to legacy AMD display adapters flashes after waking from sleep.
  • Addresses issue that causes delays when switching keyboard languages using Alt+Shift.
  • Addresses compatibility issues when rendering certain closed captions or subtitle formats during video playback.
  • Addresses issue where the Microsoft Edge Allow Extension Group Policy for the disabled state was not working.
  • Provides additional protections for 32-bit (x86) versions of Windows 10, version 1709.
  • Resolves the issue reported by some customers on a small subset of older AMD processors where the processor entered an unbootable state after installing January 3, 2018—KB4056892 (OS Build 16299.192).

You should receive this update over the next few days automatically through Windows Update. But if you want to get on top of things, head to Settings > Update & Security > Windows Update to check for the latest build. You can also download and install it manually from the Microsoft Update Catalog. Keep in mind a restart will be required to complete the update.

After installing today’s update let us know how your PC is running. If you’re having any problems, check out our Windows 10 Forums for additional troubleshooting advice.

    After this update a new, and totally unknown user emerged on my PC. The information from this user folder says it has been created before I bought my PC. It is named by a person’s name unknown to me and contains folders with photos, excel-files, music, pdf-files, videos etc. (I bought this new PC this fall.) I tried to delete the new user, but was not allowed to do it. I tried to prevent the user with my F-secure, but the user-folders are protected, and again, I’m not allowed to delete this new, unwanted user on my PC.
    Never happened anything like this before, and I’m quite baffled.
