Looks like its a problem with the Rip & Burn plug-in and Virtual Disc Drivers. Uninstalling either will prevent the crash.
EDIT: Should have checked this earlier, but its mainly the Sonic Engine.
Playing a music CD with Sonic Engine,
opening the "Send to:" Menu with Rip & Burn installed along with a Virtual Disc Driver and
possibly using the Rip and Burn Features will Lock up Windows 7 (Seven) forced to manually restart.
Disabling Sonic Engine in the
Nullsoft CD Plug-in (in_cdda.dll) and
Uninstalling the
Nullsoft Rip & Burn plug-in (ml_disc.dll) will prevent the Lockups. I guess until the Sonic engine is updated for Windows 7.
