Microsoft has released a new build of Windows 10 to Insiders on the Fast Ring. As with previous builds beginning 10586, this build too does not bring any new features but performance improvements what Microsoft calls "code refactoring."
According to Microsoft’s Gabe Aul, here is what’s improved in build 11099:
As with the previous build, this build does not include big noticeable changes or new features yet. Our focus through the holidays was on structural improvements to OneCore, which is the shared core of Windows across devices. The code refactoring and other engineering work we’ve been doing to optimize OneCore is nearing the point where we will be ready for teams to begin checking in new features and improvements. It will still be a few builds before any really noticeable changes show up, depending on when teams begin lighting up new features in their areas. We’re excited for Insiders to use this build to validate the work we’ve been doing to OneCore, so give this build a try and let us know of any issues you run into via the Windows Feedback app.
One thing to notice, Gabe didn't touch "Known Issues" topic in the blog post. That is because from now on, Microsoft will be publishing known issues for builds in the Insider Hub rather than in the blog posts.
Here are the known issues:
- Log on for devices using Citrix XenDesktop may be broken. It is recommended that Insiders that use XenDesktop skip this flight by moving to the Slow ring.
- Applications that depend on Adobe Flash may crash upon launch. This will affect some version[s] of Skype, QQ, WeChat, etc. This does not affect Microsoft Edge of Internet Explorer.
- With this build, defaults for some applications will be reset. Music & Video will default to Windows Media Player. This can be reconfigured opening Cortana or Search and searching for “Choose default apps by file type” to open the correct settings page.
Also, Gabe added:
I do want to note something that we fixed in this build which was a known issue in the last build: the progress dialog when copying or deleting files via File Explorer now shows up as expected.
