I recently bought a Dell Studio Laptop with Windows 7 Home Premiun. I noticed that a lot of times there are multiple explorer.exe processes running. First I saw about 5. I thought maybe its normal in Windows 7. Because there are always about a total of 70 processes running. But today I say 11 (yes 11) explorer processes. Is this normal in Windows 7? Because this surely doesn't happen in XP. Sometimes when I shut down the computer a message is displayed saying: "Waiting for process to play shut down sound: explorer.exe" Could this be a virus? Its been less than 2 months since I bought the laptop.
