Bugs[edit | edit source]

UEFI BIOS[edit | edit source]

This build can only be installed on machines utilizing UEFI firmware since it hangs on a legacy BIOS system.

Window thumbnail border color error[edit | edit source]

If window auto-colorization is enabled, the window thumbnail borders on the taskbar 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 restarting Windows.
