I downloaded from Microsoft site Windows Server 2008 R2 SP1 4-in-1 evaluation (Standard, Enterprise, Datacenter, Web) and I installed in virtual machine Web Edition. I have one question: This evaluation is 10 days, activating evaluation, license is valid for 180 days. Is it possible to activate evaluation with activator forever (license to be valid forever) ? If yes, which activator should I use ? Thanks in advance.
