Here's what's fixed and broken in Windows 10 Insider build 14965

Microsoft has pushed out a new Windows 10 PC and Mobile preview build for Insiders on the Fast ring. As usual with these builds, not only are there new features and changes to check out, but Microsoft has also thrown in plenty of fixes to be aware of as well. Alongside those, however, are some known issues to take a look at as well. Here's the breakdown of what's fixed and broken in Windows 10 preview build 14965 for PC and Mobile.

Improvements and Fixes for PC

• We have fixed the issue causing Internet Explorer to crash a few seconds after launch.
• We fixed an issue where, when using Cortana in French (France or Canada), the "Prendre une <photo/video/selfie>" (take a picture, video, or selfie) command was redirecting to a Bing search rather than opening the Camera app as expected.
• We've made some graphics improvements so the system will now respond better when WIN + L is pressed while playing a full screen game.
• We've updated the ALT + F4 Shutdown dialog to better respond to DPI changes when connected to an external monitor. We also fixed an issue where the tooltips for the taskbar notification area items would be incorrectly sized after a DPI change until rebooting the machine or otherwise signing out and back in.
• We've fixed an issue where File Explorer might crash when creating or renaming a folder on a network share.
• We fixed an issue resulting in the text on the Outlook Calendar tile on the Start menu being slightly fuzzy.
• We fixed an issue where deleted files might reappear in File Explorer with a 0 byte size.
• We fixed an issue resulting in a Windows Default Lock Screen window sometimes appearing after logging in.
• We fixed an issue resulting in File Explorer crashing after right-clicking an app in Task Manager and selecting "Open File Location".
• We've updated our migration logic so that going forward from Build 14965, preferred UAC settings, startup shortcuts, and File Explorer folders that had been pinned to the Start menu will all now be preserved across upgrades.
• We fixed an issue resulting in vertical lists written in XAML, such as those found in Groove Music, unexpectedly animating in from the side.
• We fixed an issue resulting in Cortana crashing if you typed "Create an appointment" then clicked on the resulting suggestion to "Create an appointment".
• We fixed an issue where in Microsoft Edge, after cancelling a file download, the progress bar for the next file downloaded might appear to be stuck at the point at which the old file's download was at when it was cancelled.
• We fixed an issue that could result in the Japanese Input Method Editor (IME) periodically showing the candidate window in the upper left corner of the desktop and not being able to enter text into the Office 2016 apps and some other text editors.

Known Issues for PC

• Double-clicking on an Excel document to open it from File Explorer will crash Microsoft Excel. The workaround is to open the document from within Excel.
• Microsoft Studios games like Microsoft Sudoku, Jigsaw, Minesweeper, Taptiles, and Treasure Hunt may freeze at the splash screen on launch.

Other Improvements and Fixes for Mobile

• We fixed an issue where, when using Cortana in French (France or Canada), the "Prendre une <photo/video/selfie>" (take a picture, video, or selfie) command was redirecting to a Bing search rather than opening the Camera app as expected.
• We fixed an issue resulting in Cortana crashing if you typed "Create an appointment" then tapped on the resulting suggestion to "Create an appointment".
• We improved the performance for English (India) text prediction.
• We fixed an issue in Data Usage Settings, where after selecting the data plan to be unlimited, it would still prompt to set a limit. We've also made it easier in the Data Usage Settings for those with dual SIM phones to differentiate between the cellular data use on each SIM, and fixed a few other polish issues, including that the sort by dropdown on the Usage Details page was unexpectedly wide.
• We fixed an issue where Narrator wasn't giving feedback when adjusting sliders, for example in Settings, or in the Volume flyout.
• We fixed a migration issue resulting in Microsoft Edge to fail to launch for some Insiders after updating to a new build.

Known Issues for Mobile

• If you used the previous 'date change' workaround to update to Build 14951 or Build 14955: Please don't use it any longer! The Microsoft account (MSA) ticket on your device needs to expire and then you'll be offered today's build. If you changed your date by 30 years… you'll want to do a device reset.
• You will be unable to install additional languages, keyboards, and speech packs on your phone for the next few weeks. If you have existing languages, keyboards, and speech packs installed – they will carry over when you update to new builds. You just can't install any new ones. If you do a hard reset of your phone on these builds – you will also be unable to install additional languages, keyboards, and speech packs. You can use Windows Device Recovery Tool to go back to Windows Phone 8.1 or Windows 10 Mobile, install any languages, keyboards, and speech packs you need and then update to the latest build in the Fast ring as a workaround.

And that's it for the fixes and known issues in build 14965. For the full details of what's new, make sure to check out our Windows 10 build 14965 announcement post!
