Dell bluetooth headset doesnt work in windows 7,was working in windows vista

The Dell bluetooth Head set doesn’t work post my upgrade to Windows 7 RTM. After researching on different forums and blogs, it seems we may have some issue with this hardware due to non-compatibility of drivers post your release of RC1 .Please help

After all the troubleshooting and no answers from any official support, heres the answer to this problem:

Installing Bluetooth Headset in Windows 7 / Windows Server 2008

Due to the fact that Windows Vista doesn’t support Bluetooth headset profile, if you want to use a Bluetooth headset with your adapter, you’ll need a little creative workaround to add the headset profile to the default Microsoft stack. Download either of the x86 or x64 compilations of the CSR Bluetooth driver and extract its contents to a folder. When you try to pair your headset to your computer, Windows will ask for drivers for the headset since it doesn’t find the appropriate headset profile. Point Windows to the folder where you have extracted the CSR drivers to make it work. Make sure you go into the device in the Bluetooth Devices panel and check off the boxes for headset, etc.

    Only the drivers for the stereo sound wouldn't install, which is a pity as the headset sound quality is like telephone quality. Researching further for getting this working. Cheers!!!
