The users experience a 3 minute delay at logoff when Google Drive File Stream is installed. The SLtraceLogoff.htm shows the information on the image below:

The presence of a Google Drive File Stream drive mapping is triggering a dormant section of code which was previously only used for Windows 9.x clients. Since it is no longer necessary to retain the Windows 9.x section in the code, it has been removed from the SLStart.exe file.
