I’ve been having problems playing CDs on Windows: if I have Windows Media Player running and I switch (audio) CDs, WMP never recognizes that the CD has changed. I couldn’t figure out what was going on; I even upgraded WMP to the latest beta (which, it turns out, I intensely dislike), but that didn’t solve the problem.
So I decided to install iTunes; I’ve been impressed with it on Mac. When running the installer, the following dialog popped up: “AutoRun is turned off. iTunes won’t be able to recognize when a CD is inserted or ejected until your computer’s AutoRun setting is turned on. Do you want iTunes to turn on AutoRun for you? [Yes] No”
Whoa! One of the first things I do with every Windows install is disable autorun. This is because I sometimes insert CDs that I don’t trust, and occasionally USB sticks as well. I don’t want autorun on! But I do want my media player to be notified by the OS when I’ve inserted a new CD. Why would the AutoRun setting have any affect on this? I hate that. But at least I know what’s going on.
