New features and changes[edit | edit source]

[HKCR\CLSID\{3f97e701-2fad-40b5-90fc-77ca1a723a3a}]
"AppID"="{8F09011C-9A2A-4BBD-A04F-FF1C635DBCA3}"

Bugs and quirks[edit | edit source]

USB 3.0/xHCI[edit | edit source]

This build includes a non-functional xHCI driver and will not boot if USB 3.0 or later is enabled. Disabling USB 3.0 from the VM configuration (or through the physical machine's BIOS/UEFI firmware) will allow the build to boot normally.

DWM and Aero[edit | edit source]

  • The Windows Basic and the High Contrast themes do not properly render due to the enforcement of the DWM Aero theme.
  • Only the top portion of the window frame is blurred when using the Windows Aero theme, leaving the side borders transparent.
