Bugs and quirks[edit | edit source]

Filesystem mounting support[edit | edit source]

The shell may attempt to invoke a Windows Explorer window that navigates to an unoccupied drive letter before an ISO image is able to finish mounting, in turn displaying an invalid path error. The ISO image will still have mounted normally, and can be accessed through ordinary means. Virtual hard disk (VHD) images are confirmed to not be impacted by this bug.

USB 3.0/xHCI[edit | edit source]

This build appears to have a broken xHCI driver, and therefore will crash during boot if USB 3.0 is enabled. Disabling USB 3.0 for the VM (or from BIOS/UEFI, on real hardware) should fix this problem.

Compatibility[edit | edit source]

To install this build or run this build in VMware Workstation, the hardware compatibility must be set to version 9.x or 8.x; otherwise, a bugcheck will occur.
