Bug ID: 48430
           Summary: Windows 2008 VM has broken Media Foundation libs
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: wine-bugs@winehq.org
          Reporter: jacek@codeweavers.com
      Distribution: ---
I noticed in user32:winstation tests that there is weird window
"mfreadwrite_test.exe - Unable To Locate Component" messing with foreground
window tests:

I investigated a bit deeper and it seems that the installation contains
mfreadwrite.dll, but not mfplat.dll. When you attempt to load mfreadwrite.dll,
Windows shows an error dialog about incomplete installation like:
https://testbot.winehq.org/JobDetails.pl?Key=62943&s104=1#k104
It seems that there is a separated installer for MF for win2k8:
https://www.microsoft.com/en-US/download/details.aspx?id=20424
I can see a few solutions:
1. Try to install MF into VM and hope it helps (and ignore failures on
installations missing MF).
2. Load mfplat.dll and mfreadwrite.dll dynamically and skip tests if mfplat.dll
is missing (this would make code uglier for a questionable benefit).
3. Get rid of win2k8 VMs and consider them unsupported. This may seem radical
for the above problem, but I don't see any value in win2k8 test results in
general.
