Since the release of build 10041 for PCs we’ve continued to make steady progress, and as I said in the blog post with that one we’re working to bring you builds to the Fast ring faster than before. Builds last week were BIG ones for us as well, since “Project Spartan” was integrated into our flighting branch for the first time. That’s right, this means that today’s release includes the new Project Spartan browser and you’ll get to use it for the first time on PCs as it begins to show up across the Windows 10 device family.
As I mentioned on Friday, we are also working on the next build of Windows 10 for phones and plan to support a bunch of additional phones in the next build for phone as well as some great new features. As always, I’ll share info with you on that as soon as I can.
Build 10049 is about a week newer than 10041, so besides Project Spartan what you’ll see in this build will be mostly small improvements and fixes, as well as a few new known issues.
Here are some issues we fixed in this build
- 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.
Here are some known issues for 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.
- UPDATE: You cannot enable Hyper-V on this build. If you have Hyper-V already enabled and you upgrade to this build, Hyper-V will continue to work.
If you have Virtual Machines hosted in Hyper-V 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 build is pretty much all about Project Spartan, so we hope you enjoy getting your hands on it for the first time. As with all other new features we’ve introduced, we have a ton of work left to do with Spartan so expect to see some bugs and rough edges in this first preview. As always, we look forward to hearing your feedback via the Windows Feedback App.
Note – we won’t publish ISOs for this new build until we push it out to the Slow ring. Today we are only pushing to the Fast ring.
