My Imac running windows 7 was sooooooo slooooow that it could take up to minutes to do the simplest task ie opening a file or a music/vid file, if I tried to fast forward a vid for example if could take up to a minute. I did the usual anti virus, malware........ I tried loads of forums but all said drivers etc... I couldn't remember which version of bootcamp I had and tried 4 or 5 different versions only to get "this version of bootcamp ins't compatible with your mac blah blah" I looked in device manager, other devices, some bluetooth stuff with driver probs. I went to control pannel, devices and printers and removed the various bluetooth items with driver probs, xps? doc writer and all the junk windows 7 has but I don't use. Now my imac is running perfectly with no probs. Hope this helps
