Bugs, quirks, and observations[edit | edit source]

DiskPart[edit | edit source]

Diskpart will report after launch that it is being deprecated and might not be available in a future release.^[2]

Localization[edit | edit source]

Many strings throughout the system may contain garbled text in the Chinese language and the Japanese language versions of this build.
Since not all of the strings have been translated yet, some places remain in pseudo-localized English in the German language version.
In the German language, the Microsoft confidential text on the watermark cuts off early.

High Contrast Window Color page[edit | edit source]

By entering the High Contrast Window Color page, then in another window switching to Windows Basic followed by applying a change in the Window Color page, Windows will temporarily apply a nearly empty visual style, causing Windows Classic elements to be seen in all applications, while allowing Desktop Window Manager to function and still be toggled, and completely breaking new Explorer and Control Panel windows, some Charms Bar functionality, and the Start Screen if enough time passes. This can be fixed by simply logging out. Trying this with Aero will result in the visual style being switched to Aero Lite instead.
