It could be that Windows Media itself (an already annoying and over-demanding program) is trying to run some sort of reminder, or updater, or some other process. Make sure you go into the options and check through all of them. Turn off things like "Run at startup" and "check for updates every day" and other things that make it run when you don't want it to.
Basically, if it sounds like it's an option where the program does something without you telling it, disable it!
I guarantee you 130% it's not Aces High that did this. AH was simply minimized by something else, it didn't start that "something else." AH was the victim
