Do you hate activation. I just wish people would pay for the software ... (ok take a breath)
To check your eval time type: slmgr -dli
To add more time to your eval type: slmgr -rearm
Once done with eval - pay for license.
Note you must use a command prompt with elevated priveleges so right click command prompt icon and run as administrator
