Hi there, I'am confused on activation of Windows 8.1 VL EN_US. I've got an image with the following name: en_windows_8.1_professional_vl_with_update_x64_dvd_4065194.iso with the following checksum(s): File: en_windows_8.1_professional_vl_with_update_x64_dvd_4065194.iso CRC-32: 05a02af4 MD4: 449d33feb47d035645299da3b3477c21 MD5: 9b2bf609db207af3817167d8a6b87e62 SHA-1: e50a6f0f08e933f25a71fbc843827fe752ed0365 Burned the image, installed it, system runs, but how do i activate/register this Windows 8.1 Pro version. I've read some posts on the forum on the subject, but it gets more confusing for me by the minute. (No valid Windows 8 serialnumer at hand here, I think activation by phone doesn't work for me.) Could someone please tell me on how to proceed in this further, it would be very appreciated. Thank you in advance.
