Running Win 7 Pro and on start up I receive an error message BtTray.exe. Error message says the dll is missing from my computer. After Googling, I found it has to do with Bluetooth and don't kno how it was deleted. One of the articles said in Start Up to disable it but cant find it in start up (Bluetooth Tray Application) I would delete it totally or disable it if I knew how. the .exe I believe has to do with HP Bluetooth and since I never use it, would like to get ride of it totally or disable it. Its another message to deal with on start up and I wish I knew what I did to have created this error. Any Help??
