Windows 10 Build 17112 release: repair EFI and recovery partition problem

Today, Dona Sarkar, head of the Windows Insider project, announced the release of the Windows 10 Build 17112 update for Fast channel users, who are eager to try out early this weekend. This version of the update did not introduce new features, mainly in the BUG fixes and background performance tuning, I believe the development of Windows 10 Redstone 4 has come to an end, Microsoft will focus on maintenance.

Windows 10 Build 17112 mainly fixes and improved the following:

• 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.
