There's a tool to clean up after removing Office 2010, which includes removing the Q Drive. I can't remember exactly where I found it so I'm attaching in a zip.
Incidentally I had nothing but trouble with the "Click to Run" set up and gave up on office 2010. But you can now get a "standard" or off-line installer for a 60 day trial. Here's a Link Removed - Invalid URL link (you can get it through official M$ links as well, I just didn't want to sign in to get the links!!). It's a chunky download at 585mb but at least it installs just the bits you want!!
