The "Click-to-Run" virtual drive (Q:) is created when Office Starter 2010 is installed. The following two white papers provide prescriptive image creation steps to relabel this drive, and include registry keys to avoid anti-malware incompatibility.

Microsoft Office Starter 2010, which will be preinstalled on OEM machines, uses the new Click-to-Run (C2R) technology to host the Office Starter files in a virtualized application space. This restricted space is mapped to a drive that cannot be accessed by the user, but is visible in Windows Explorer. To help communicate to the user that this drive is not accessible, Microsoft provides OEMs with the ability to label this drive with a more descriptive localized label.
