bluetooth bDongle driver  

Hi, i have bought a bluetooth dongle as my laptop does not come with bluetooth installed, but i forgot i was on windows 7 and did not check it, it does not say it supports win 7 ,have i bought a dud,, its coming up there is no driver and i cant find one anywhere ,it has no make name on the packaging just say usb dongle, also i think i need a driver for my mobile phone, i have used a blutooth dongle before to pair with my phone with my computer but im stuck as to what i need to do now
hope someone can help, many thanks Pearl x

hi. thought i would leave an answer in case anyone else has the same problem , i sorted it by simply allowing windows to update new drivers , it them worked fine.
