Hello, I have the following: Toshiba Satellite L50t-A Part No.: PSKLJU-043038 it came with Windows 8.1 Core. I would like to install Win 8.1 Pro WMC. Is there any way that I can upgrade/install Win 8.1 Pro WMC with the default drivers that came with this notebook? I tried many different ways, but the computer is tied into Core via the BIOS. Is there away to navigate around the BIOS or some how "hack" the BIOS to install Win 8.1 Pro WMC? I tried different types of activation including Microsoft Tool Kit, Windows Loader, etc. I would really appreciate any and all help with this issue. Thank You.
