I've got a Vaio laptop model SVF14A15CXB that came with windows 8 standard. Whenever I try to install windows 8 pro with CD and the Key the install completes correctly but when it's installed it shows that Windows 8 standard is installed, not Pro. I've done a complete clean install deleting all partitions. I've activated it with the Win 8 pro Key and it accepts it but it still shows up as Win 8 standard after the installation.
