Fixes and improvements in Windows 10 build 20201

  • Microsoft fixed an issue where some Microsoft Store games protected by Easy Anti-Cheat failed to launch. Some games may still need to release an update to fully resolve the issue.
  • Microsoft fixed an issue where the IME mode indicator in the taskbar was indicating that the IME was enabled when it was actually in a disabled state.
  • The company fixed an issue in the last few flights resulting in HDR monitors appearing black when HDR was enabled.
  • Fixed an issue where the min/max/close buttons were stuck in their original positions after resizing a UWP app.
  • Fixed an issue where SetInputScope wasn't working if it was called after the app had been initialized.

 

Known issues in Windows 10 build 20201

  • Microsoft is looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • They are investigating reports that the new taskbar experience for pinned sites isn't working for some sites.
  • They are working on a fix to enable live preview for pinned site tabs.
  • They are working on enabling the new taskbar experience for existing pinned sites. In the meantime, you can unpin the site from the taskbar, remove it from the edge://apps page, and then re-pin the site.
  • They are working on a fix for an issue where pinned sites don't show all open tabs for a domain. In the meantime, you can fix this by pinning the site's homepage rather than a specific page (e.g. pin microsoft.com rather than microsoft.com/windows).
  • They are working on a fix to resolve syncing issues in the Mail app with certain mail services.
  • They are also working on a fix for an issue where Office documents may open blank when opened from File Explorer. If you encounter this issue on this build or Build 20197, the file should render correctly if opened from within the app rather than File Explorer.
  • They are investigating reports of some Office applications crashing or missing after updating to a new build.
  • They are investigating reports of some devices receiving a bugcheck with error code KERNEL_MODE_HEAP_CORRUPTION.
  • They are also investigating reports of the Settings app crashing when opening Manage Disks and Volumes.

 

Microsoft also released ISO/DVD image for Windows 10 insiders preview build 20201, which you can download from the Windows Insiders download site for offline installation.
