I just installed an eval copy of windows server 2012 (datacenter) core.

It says its a 180 evaluation, but checking the licensing info I see this:

enter image description here

Is this different for core installs than GUI because I have used the same iso to do full GUI installs and it always gives me 180 days.

I should also add when downloading the trail I was not provided a license key.


You never activated it online...you have to do that to allow for the full 180 days.

For all editions, you have 10 days to complete online activation, at which point the evaluation period begins and runs for 180 days.

  • yep...same as the GUI. There ya go. – TheCleaner Oct 29 '13 at 13:37
  • Felt silly after asking this because I just remembered having to do it for my previous full GUI installs. I guess because this was a core install I never saw the watermark and totally forgot about it. – red888 Oct 29 '13 at 15:37
