From: "Rich Gauszka" 

on a side note: still can't use the TechNet forums while signed on to my
hotmail account as I'm still banned for arguing in the wga forum last year.
I did contact the MSDN concierge about it a while back but the concierge
couldn't find any reason and just suggested that I set up a new hotmail
account which I'm not going to do

 Thank you for your response.

Based on your reply, it seems that Microsoft Bluetooth stack has certain
issues on Windows Vista. Please correct me if I am wrong.

James, I would be more than happy to provide you with the drivers for your
Mobile Bluetooth Headset but there are no drivers available for that
headset. The headset works natively on the Microsoft Bluetooth stack and it
appears on your last email that you receive the message prompting you to
update the headset drivers but the headset does connect and work. I would
suggest that at the moment until Microsoft has a work around on this issue,
I would suggest that you ignore the message which you receive. I apologize
for any inconvenience caused in regards to Microsoft.

Please do let me know should you require additional information or
assistance in regards to this issue as I would be more than happy to assist
you further.

Thank you for choosing Logitech.
