A few reboots later, icons that I've changed manually seem to be sticking... I had assumed that they'd only change to the new ones after I've started them up, but not the case, as soon as my dock comes up when I log in, I see them. For anyone that's interested in seeing something other than the ugly 32x32 windows icons, just open up Terminal, go to ~/Library/Parallels/[VM name]/Windows Applications/[Application].app/Contents/Resources And run "open WinAppHelper.icns". If you have the Xcode stuff installed, Icon Composer should open up. It will show the crummy windows icon... click on that so that it highlights, and paste in a 128x128 PNG or TIFF. File/save, and a reboot (or three) later, it should show up in your dock, and when alt-tabbing through apps. To get you started, here's something suitable for IE6: http://www.xiaprojects.com/www/prodotti/kxdocker/xmls/icons/iexplorer.png Has anyone found one for IE7? I made mine with Gimp, but I can't get rid of the fringe from the white background, no matter how hard I try. I'd be interested in learning where some other 128x128 windows icons could be found. Also, anyone know how to keep the VM icons from showing in the dock now? With the application icons there, I don't really need the parallels icons anymore.
