Quirks[edit | edit source]

Visual styles[edit | edit source]

The user's visual style preferences may not be properly respected when switching themes on the first boot; the default Luna visual style may be reapplied with the previous window metrics on the next boot. This issue specifically occurs in Far East language releases, and can be observed by switching to the Windows Classic visual style immediately after completing the out-of-box experience and subsequently rebooting.
