Windows 7: widcomm bluetooth

Widcomm bluetooth came pre-installed. With an eye at a possible bluetooth future, I didn't uninstall. I noticed my temp folder keeps getting the btn%copy%1\btn%copy%2 empty folder. An internet search netted no creator of said folder. A tool was mentioned, process monitor, which I used. Thus, Widcomm and its btn%copy.dll was identified as the culprit. Since I still don't have bluetooth gear, why is Widcomm intimately involved in the daily PC operations of explorer file transfers? Is this like iexplorer being integral to Windows despite the use of a different browser?
