Hi all, I have an extra USB icon on my system tray in Win 7. I have the vmware installed on this machine. The USB icon shows my HDD drives! I think it appeared when I uninstalled Intel Rapid Storage Technology (IRST) app. I uninstalled it because I wouldn't think that IRST does anything useful on my desktop PC. Now for getting rid of that extra icon do I need to reinstall that IRST!? What does it do actually in my PC please?
