    Description

      Tested build: 0.4.16-dev-2636-g02c744d

      Starting from Hyper-V in 24H2 (and now that ATAPI driver works there), the vertical mouse movement on NT 5.2 and older guest OSes is inverted (moving the mouse down moves the cursor up and vice versa).
      The issue could be solved installing the Integration Services in the guest OS but currently it's not possible in ReactOS due to ACPI and HAL incompatibilities.
      Community users that use XP on Hyper-V make use of SakasaMouse that inverts the movement to compensate the issue.
      ReactOS technically could detect the presence of Hyper-V's VMBus and invert the coordinate automatically without having to rely on third party apps.
      (another issue will track the Integration Service issue)
