Windows 10 build 10049 known issues

Windows 10 build 10049 rolls out with Project Spartan and several known issues.

Windows 10

Microsoft has just released a new preview of Windows 10 (build 10049) to the Fast ring of updates. The new build includes various fixes and includes an early version of Project Spartan. However, because the new build is rolling out through the faster channel, it also means that it includes more bugs than usual and fewer workarounds.

The software maker is now rolling out build 10049, but it’s details that there are several known issues with the latest bits that everyone should be aware before installing.

Below, you see a list of the known issues currently found in Windows 10 build 10049:

  • After logging in, you may see a blue screen instead of your desktop. To work around this issue, lock your PC (with the hardware button or by pressing the Windows Key + L) and try logging in again. You can also try Ctrl + Shift + Esc to open Task Manager.
  • Indexing of new email in Outlook is not working, so search results will be limited to when the last index was built.
  • If you have Virtual Machines hosted on your PC running Windows 10, you will want to move to the Slow ring and wait for the next build as this build breaks the ability to run VMs.
  • There are 2 issues using Visual Studio 2015 preview on this build:
    • The emulators will not boot and you won’t be able to deploy a Windows Universal app to the Mobile emulator.
    • The XAML designer in VS and Blend will crash when opened.
    • If you are a developer using these tools today to develop Windows Universal apps and need this functionality to work – we recommend switching to the Slow ring until we release a patch to fix these issues.

Microsoft also listed a number of fixes in this new release:

  • The software maker fixed the issue from Build 10041 for when the Photos app on your PC crashes when you tap on the circular icon at the top left to view the photo you just took.
  • The company also fixed the issue from Build 10041 where you might end up in a state where windows open on your desktop are accidentally visible behind the Start Screen, Task View, Snap Assist, and when rearranging windows in Tablet Mode.
  • You will no longer get stuck when you manually lock your PC (Windows Key + L) during the initial out-of-box experience.
