I just noticed in the Task Manager a while ago that "Windows Driver Foundation - User-mode Driver Framework Host Process" under "Background Processes" was running at about 50% of CPU constantly. I did some research and found out that this only seems to happen when Windows Media Player is running. It seems to happen even when Windows Media Player is not doing anything, when it's not even scanning for new media. When I close Windows Media Player, the "Windows Driver Foundation - User-mode Driver Framework Host Process" CPU usage drops immediately to 0%. I have looked for a solution to this, but could not find anything that worked. If anyone here knows about this problem and how to solve it, I would be greatly appreciative.

SOLUTION: Let it run its course. It might take several hours or even a day, but eventually it will stop. The reason it's using CPU is that the RealTek driver had just been updated, so the Windows Driver Foundation - User-mode Driver Framework Host Process "optimizes and compresses drivers after installation", as someone noted in this thread on another board that I found while researching this issue - http://en.community.dell.com/support-forums/mobile-devices/f/4586/t/19615499.
(Since I can't select one of my own answers as the "solution",
I decided I should edit my original post and put the solution there, so that people could see it immediately. Because I always get e-mail reminders to select a solution if I don't do so after a month or two - and because this thread should appear to be an "answered question" and not an "unanswered question" - I'll go ahead and select one of Ralston18's replies as the "solution", since he was so detailed and considerate in his responses, and what he wrote would be helpful to others in this general type of situation where you need to figure out why a process is using up so much CPU. Thanks again, Ralston18.)
