Not the best driver and not satisfying with SP2 for Windows XP
You need to replace the SP2 driver with this using update and override all the controls (select the driver yourself)

no idea what this was but cause of this prozess my complete upload was used.
On sony vaio VGN - CSxxx preinstalled. don't remove it! or install another driver.
I found BTStackServer.exe in my Lenovo software pack at C:\Program Files\Lenovo\Bluetooth Software so I renamed it to ensure it did not get re-loaded. My machine now runs Bluetoothmanager.exe from C:\Program Files\Lenovo\Bluetooth Manager, and the result is MY CPU was running at 30% and RAM was near 80%, and now it is 5% CPU and 45% RAM. And everything works. I got suspicious when I found the bluetooth mouse and keyboard were very slow.
If Skype tells you it wants access, it's so you can use bluetooth headsets. If you don't care, you can say no.

Best practices for resolving BTStackServer issues

A clean and tidy computer is the key requirement for avoiding problems with BTStackServer. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem.
