I writing this to warn everyone about a problem which affects Skyrim and seems to me to be caused by some of Windows Media Player's more parasitic behaviors.
.
This last week, during testing, I noticed the game performance stall quite suddenly and severely with attendant and ongoing hard drive access which could not be explained by any of the programs running in the foreground. In this case, I was not running the Creation Kit in tandem with the game, nor was I making any attempt to stress test the system. Moreover, this is not the first time something, fired up by the operating system, had destabilized the game during low-stress testing.
.
When I opened the task manager I caught Windows Media Player, red-handed, running a "network synchronization" routine which had been initiated while I was in-game and without my express consent. It is worth pointing out that Windows Media Player was using resources that had only just been allocated to Skyrim and, no less, while Skyrim was still in use and still had the focus. Consequently, Skyrim started experiencing severe difficulties because of this uninvited theft of allocated machine resources (be they allocated CPU registers, allocated cache or allocated memory). Given that I never watch DVDs on this system, Windows Media Player never has any reason to run on this particular system - unless it is not a "media player" but something else dishonestly labelled as a "media player". Take your pick. Either way it's certainly not above board.
.
Since disabling Windows Media Player, and all it's associated services, this particular problem has not recurred on this system. I hear that Microsoft does not allow Windows Media Player to be uninstalled, and I am wondering if, perhaps, someone could explain to me what happened to the court ruling expressly ordering Microsoft to ensure that all users must be able to uninstall such "features" (e.g. internet Explorer) if they so choose...?
.
I suspect that a lot of valuable time expended by a great many people, including myself, has been wasted by this particular problem so, what am I to say?
.
Shame shame shame, Microsoft.

And for those of us chasing our tails over 'Skyrim' bugs, some of which, evidently, do not originate in the game - disabling Windows Media Player (and all its associated services) during testing might bring some sanity to the bug-hunt.
