    That's exactly what i was going to do at the begining, but i have to find exacly the words like "Licensed" or "Grace period" in the output for then returning em to an edit... it'd be boring. Plus i want something else than always dealing with slmgr

    I think you'll find it'll only output as 0 or 1. You have to convert that data.

    Slmgr /xpr showns the product activation.

    C#:
    Code:
    bool Licensed = false;
                try
                {
                    foreach (ManagementObject Obj in new ManagementObjectSearcher("root\\CIMV2", "SELECT LicenseStatus FROM SoftwareLicensingProduct WHERE LicenseStatus = 1").Get())
                    {
                        Licensed = true;
                    }
                }
                catch (ManagementException) { Licensed = false; }

    Here is how to check the License Status with Microsoft C++, compiled with VS2010.

    It uses WMI but I've edited it and it takes less than a second to check.

    Download the source here.

    Hey, ok i've been learning WMI and i notice it's really cool stuff. I can access several low level infos with this, thx all of you. i'm now learning C++ since i can't use Qt with C, besides i'm fed up with WinAPI which is hard to handle and lots of code for little things, nah...
