I have a Windows 8 Evaluation Copy that had a 90 day deadline when I installed it. How do I check how much time I have left to use the OS, and what are the drawbacks I will face in the Evaluation copy when compared to RTM?
Open a command prompt and use
Below are all the commands to check the license.
The number of days you have left will be on the bottom right corner of your desktop. Once the evaluation is over the system will have its wallpaper changed to a plain back one, reboot every hour and you will get reminders its not genuine windows.You cannot upgrade from it into a new installation.
Biggest drawback here is you have an install that will work at most 9 months (3 months a trial, with three rearms if its allowed), and activations will only work till august 13 next year
The evaluation copy is an evaluation copy (holy tautology batman!). Its fine for throwing onto a VM to see if something will work, or for a copy for testing something on the short term. The Standard(core) and Pro releases are for systems you actuallly care to see running properly on the long term.
