While Windows Media Player continues to sneak all this DRM and information-gathering in on you (10 is the worst yet), it has some additional really broken functionality that annoyed the crap out of me today. I couldn’t seem to grab a screenshot of an avi clip I was playing. Media player, Zoom-in, and MS Paint were in cahoots to defeat me, so don’t tell me it’s not intentional. :> Finally “beat the system” with good old Winamp.
Moral: switch to Linux while it’s still legal.
