The feature may cause logger to walk through folders on a remote server calculating project complexity. The feature does NOT send your project to Microsoft, it just collects some statistics on the project. If you are experiencing slow project close, try switching off participation in the feedback program in Help | Customer Feedback Options... dialog. If it does not help, try disabling component in registry by changing
