I would believe that, if the installed drivers wouldn't have different versions and the reinstallation even asks to replace an existing file with an older one (the reinstallation of Parallels Tools).
(I did the upgrade and after that I downloaded the full installer and installed from that, I'm 100% positive the drivers installed on Windows are a more recent version than that that's on December's 4810, the newer ones even refer 23st January).
Not to mention that the version referred on the boot screen of the VMs says 4.0.3810.351321 (instead of 4.0.3810.237520) if I use the full installer, and remains unchanged (4.0.3810.237520) if I just use the upgrade.
