If a program is started elevated (with elevated privileges) by using "Run as administrator" for example does not allow non-elevated programs to drag files into it. This could be a security issue, because a non-elevated program could be told to delete files/launch malicious programs. If you run "Explorer.exe" as admin, this is no problem, as elevated programs can communicate with other elevated programs. I recommend not to do this because it effectively disables UAC. To do it nonetheless, you gotta close "explorer.exe" using task manager first, then start a new process elevated.
