Windows 10 build 17112 now in the Fast ring - here's what's fixed and broken

If you're on the Fast ring, it's once again time to check for updates on your PC. Today, Microsoft released Windows 10 Insider Preview build 17112. There are no new features, but there are a bunch of fixes and known issues.

This is actually the second new build from the Redstone 4 development branch this week, the first being 17110, which was released on Tuesday. Normally, the Fast ring sees new builds weekly, but since we're now just weeks away from an RTM, they're starting to show up more frequently, and they're focusing on fixes, rather than features.

Here's what got fixed in build 17112:

• We fixed an issue where selecting a notification after taking a screenshot or game clip opened the Xbox app’s home screen instead of opening the screenshot or game clip.

• We fixed an issue where EFI and Recovery partitions were unexpectedly listed in Defragment and Optimize Drives.

• We fixed an issue optimizing drives in Defragment and Optimize Drives didn’t work in the last few flights.

• We fixed an issue resulting in a permanently black window if you dragged a tab out of a Microsoft Edge window, pulled it up to the top edge of the screen, and moved it back down and released it.

• We fixed an issue where the warning on Windows 10 S when trying to run non-Microsoft Store apps from File Explorer might end up stuck behind the File Explorer window.

• We fixed an issue where there was some unexpected extra space in the File Explorer navigation pane before the chevron icons to expand/collapse folders.

• We fixed an issue where if focus was set inside Action Center pressing Esc wouldn’t close the Action Center window.

• We fixed an issue that could result in ShellExperienceHost periodically waking the device from hibernate if active live tiles were pinned to Start.

• We fixed an issue where navigating to Settings > System > Focus Assist > “Customize your priority list” could crash Settings.

Here are the known issues:

• IMPORTANT: The Microsoft Store may be completely broken or disappeared altogether after upgrading to this build. Please see this forum post for details including a workaround on how to get the Microsoft Store back.
• If you try to open a file that is available online-only from OneDrive that hasn’t been previously downloaded to your PC (marked with a green checkmark in File Explorer), your PC could bugcheck (GSOD). You can work around this problem by right-clicking on these files and selecting “Always keep on this device.” Any file-on-demand from OneDrive that is already downloaded to the PC should open fine.
• Post-install at the first user-prompted reboot or shutdown, a small number of devices have experienced a scenario wherein the OS fails to load properly and may enter a reboot loop state. For affected PCs, turning off fast boot may bypass the issue. If not, it is necessary to create a bootable ISO on a USB drive, boot into recovery mode, and this this will allow bypass.
• When Movies & TV user denies access to its videos library (through the “Let Movies & TV access your videos library?” popup window or through Windows privacy settings), Movies & TV crashes when the user navigates to the “Personal” tab.

We reported on the Microsoft Store going missing in build 17110 earlier this week, and although the workaround apparently doesn't work for everyone, it did work on our test PCs.

Microsoft also noted that there are major issues with Windows Mixed Reality in this build. It will run at a very low frame rate (8-10fps), and the company says that this could cause physical discomfort. The only workaround is to pause Insider builds until this is fixed.

To install Windows 10 build 17112, head over to Settings -> Update & security -> Windows Update -> Check for updates. If you're not on the Fast ring yet, go to the Windows Insider Program tab and click 'Get started'.

Again, Fast ring builds are going to start showing up at a rapid pace now, so stay tuned.
