We're tracking a change to optionally configure this autofit guest behavior in ticket 1619302. In the mean time you can work around this on Windows VMs by deleting resolutionSet.dll from VMware Tools, ex. C:\Program Files\VMware\VMware Tools\plugins\vmsvc\resolutionSet.dll. Repairing or reinstalling Tools will restore the file.
