Here are the fixes, improvements, and known issues in Windows 10 for PCs build 14942

If you're a Windows Insider on the Fast ring, there's a new build waiting for you on your PC, 14942. For those that were hoping to see a new Mobile build today, which might have some of the announced Continuum improvements, you're out of luck.

Build 14942 does contain a number of PC features, although they certainly wouldn't be considered major. As usual though, there is a list of fixes, improvements, and one known issue. Here's what got fixed and improved:

  • We’ve updated Narrator’s reading order for Windows 10 apps which display an app bar on the bottom of the app, for example OneDrive, so now the contents of the page will be read before the contents of the app bar.

  • We fixed an issue where running sfc /scannow in an elevated command prompt would fail at 20% with the error “could not perform the requested operation.”

  • We fixed an issue resulting in certain areas of Windows 10 app notifications not doing anything when clicked, rather than opening the corresponding app.

  • We fixed an issue resulting in Personalization > Background Settings page crashing or showing a blank context menu when right clicking one of the recent images .

  • Fixed an issue resulting in Windows Defender’s Antimalware Service Executable sometimes using an unexpectedly large amount of CPU.

  • We fixed an issue resulting in the Devices and Printers page in Control Panel loading slowly for users with certain audio devices.

  • We fixed an issue resulting in a small set of users seeing the NTFS partition of their external hard drive incorrectly showing up as RAW format.

  • Going forward from Build 14942, custom printer names will be preserved across upgrades. We’ve also addressed an issue where the printer queue name wasn’t preserved across upgrade for some printers.

  • Improved framerates when Game Bar is enabled for full screen games.

Here is the one known issue:

  • Insiders doing web development may find themselves their local intranet server unreachable, as service host separation will leave the IIS World Wide Web Publishing Service (W3Svc) unable to start successfully. To fix this issue:
  1. Run the following from an admin cmd line (or edit the registry accordingly):
    1. REG ADD HKLM\SYSTEM\CurrentControlSet\Services\W3SVC /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
    2. REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WAS /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
  2. Reboot the system, so that the W3Svc and WAS services share a service host process.

As you can see, the one known issue offers a workaround, which leaves Insiders in pretty good shape. Keep in mind though that other issues may be added to the list - and likely will be - as time goes on.

If you're on the Fast ring, you can grab today's build by going to Settings -> Update & security -> Windows Update -> Check for updates. To sign up for the Fast ring, go to the Windows Insider Program tab and click Get started. Once your PC reboots, go back and make sure that you're set to Fast.
