Microsoft, typically giving 30 days grace or demonstration "in order to use Windows so legally past this period and we need to add the license to be activated, via Web or phone, either, as happened earlier that applying a command, the 30 days are reset to have a total of 90 days, in this case, Windows 7 will turn up to 120 days without having to activate anything, just need to apply the command:
"Slmgr-rearm"
As simple as that, and 4 months free of Windows 7, enough time to test and verify whether or not to buy the license.
