Microsoft Issues Windows 10 Build 10049 with Project Spartan To Fast Ring Windows Insiders

It took nearly two months for the Windows 10 Technical Preview to be updated after the initial release but the Fast Ring is apparently very fast right now.  Windows Insiders on the Fast Ring of Windows 10 have now had Build 10049 pushed out to them.  This update has a lot of fixes but it also is the first release with the all new singing-and-dancing Project Spartan web experience.  The update will only be available to those who are on the Fast Ring so if you are wanting to see Project Spartan and are on the Slow Ring, you will have to wait or move to the Fast Ring.

Also, if you are a developer and using Visual Studio 2015 Preview, you should not upgrade to this build.  More on why after the break.

Along with Project Spartan, there are a wide range of fixes in this release over Build 10041 that was released a couple of weeks ago.  These include:

  • We’ve fixed the issue from Build 10041 for when the Photos app on your PC crashes when you tap on the circular icon (your camera roll – thanks Rafael) at the top left to view the photo you just took.
  • We’ve 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.

In the Release Notes on the Windows 10 Blog, you will also find a list of known issues in this build:

  • 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.

This last point is really critical for you developer types as you are going to have 15 different kinds of grief if you upgrade.  Wait until the Slow Ring update in the next week or so before upgrading.

I’m currently in the process of downloading the build on my test system – are you or are you waiting for a more stable Slow Ring release?
