Windows 10 build 9926: Known issues you should know before installing

Winver command on Windows 10 build 9926

Microsoft has just released the Windows 10 January Technical Preview (build 9926) to the Insider program, and with the new build, the software giant is also allowing Windows 7 and Windows 8.1 to easily upgrade to the latest release.

Although, this is a more stable release, Microsoft warns some of the known issues in build 9926 that you should be aware, before jumping into the new operating system:

  • After installing this build, you may see a boot selection menu each time you reboot your PC. This is because a bug where a second boot option is persisted to uninstall the Windows 10 Technical Preview and roll back to the previous OS installed. When you get to this screen, if you do nothing it will automatically boot to the Windows 10 Technical Preview within 30 seconds by default or you can choose it on your own.
  • Xbox Live enabled games that require sign-in will not launch correctly. If you see the below dialog box the game requires Xbox Live sign-in. A fix for this will be distributed via WU shortly after the release of Build 9926.
  • Battery icon shows on lock screen of PCs without batteries.
  • Tiles on the Start menu show truncated app names (such as the Windows Feedback app).
  • Remote Desktop has some painting issues that result in tiled pixelation.
  • Connected Standby enabled devices like Surface Pro 3 may experience shorter than expected battery life.
  • In Cortana, reminders can’t be edited and more complex reminders might not get created. The first reminder you create in Cortana in this build might not pop up, but subsequent ones will. Completed reminders also don’t move to the History page in Cortana’s Notebook.
  • The Music app will disappear if minimized within 16 seconds of launch. Just leave it in the foreground for 20 seconds or so and it should work just fine.
  • Occasionally, the Start Menu is improperly registered and will fail to launch.

Microsoft is also working around the clock to fix these and other issues in Windows 10. For example, immediately after the software giant released the January Technical Preview, an update described as KB3034229 was released to fix some of the issues and to improve performance including:

  • Increased power efficiency to extend battery life
  • Reliability improvements for virtual machine live migrations and to prevent some system crashes in explorer.exe
  • Performance improvements for Internet Explorer

The new update also fixes the following issues that could cause:

  • A deleted app to be unintentionally reinstalled
  • Pending Windows Updates to be incorrectly reported in the update history
  • The Start Menu to be improperly registered and fail to launch
  • Random pixelation on the screen when using Remote Desktop Client
