Fixes Starfield not being able to take photos in photo mode (due to failing to creating windowscodecs' image factory due to COM apartment being initialized). Turns out on Windows RoGetActivationFactory() initializes implicit MTA apartment when called from STA thread, and so after that called once COM is implicitly uninitialized for any (new) thread until COM is uninitialized in the thread which called RoGetActivationFactory (or that thread exited). This is not the case on Win8 (where the function was first introduced) but looks consistent after that.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=137319
