Today's tip has nothing to do with Civil 3d, but this is still a valuable tip. When you install Windows 7 you have a option to activate the product upon completion of the installation process. I always like to spend some time making sure everything works together on the computer; because you may have to reinstall Windows and you know the headache involved with re-activation.
This tip allows you to rearm the 30 day activation clock up to 3 times, which gives you a total of 120 days to experiment before you have to activate.
Press the start button and browse to the command prompt under program files - accessories (Never type cmd in the search line the rearm command will not work). change the directory to c: (cd\ enter) next type in this line slmgr (space) -rearm and press enter. You will have to reboot your system but when you do you should notice the 30 day clock has been reset.
