Just got my new MBA 13.6. Installed Win 7 Ultimate absolutely smoothly. Everything works fine, but... As a matter of curiosity I opened the Device Manager and was really surprised to find two unpleasant yellow exclamation marks, one in Intel(R) HD Graphics 4000, another in High Definition Audio Device. The reason is "Windows has stopped this device because it has reported problems (Code 43)". I suspect it is not a real problem as I've seen similar issue with USB controllers and the official reply was just to ignore it. However I'd like to hear whether anybody else has the same problem. Pls, just take a look at your Device Manager. Thanks !
