General[edit | edit source]

The update process to this build has a chance of hanging for extended periods of time.
Some rendering / graphic issues may be experienced after resizing certain app windows. This should be resolved after minimizing and restoring all windows by using the ⊞ Win+D hotkey twice.
Some 32-bit systems may lose network connection after upgrading to this build.
The reliability of the Start menu and other modern apps may be affected in this build.
When Xbox Game Bar is launched from the Start menu or via the ⊞ Win+G hotkey while using a text editor, the computer may appear unresponsive. If this is encountered, dismiss the bar with the same hotkey and end the GameBar.exe process from Task Manager.
Xbox Game Bar might launch on some PCs randomly without pressing the ⊞ Win+G hotkey.
Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
