Bugs and quirks[edit | edit source]
Taskbar preview border color[edit | edit source]
If window auto-colorization is enabled, the taskbar preview borders do not change color even after the wallpaper changes. This issue can be remedied by manually changing the window color through the Control Panel or by restarting Windows.
[edit | edit source]
- Sometimes, the user must click on the start button multiple times to bring up the menu.
- Under rare circumstances and due to its earliness, the XAML start menu is largely broken and unfinished with the inability to pin/change titles and a lot of placeholders.
- The username in the XAML start menu will say "Groot" instead of the currently logged-in user's name; it is a placeholder that directly references the fictional Marvel Comics character of the same name.
- Unlike the Mexican Spanish version, the XAML Start Menu is left untranslated in the Canadian French version.
Pseudo localization[edit | edit source]
- On certain international releases, some parts of the OS have Pseudo localized translations to some English text.
