    can i upgrade my laptop from windows 8 to windows 8.1 using a system builder iso?
    my VAIO shipped with pre-installed windows 8 on it and no serial stick, so i extracted the serial from BIOS, it is a Core edition of windows 8 x64,(don't know if i got single language or not!) and found someone that shared a genuine untouched iso of windows 8.1 non-PRO OEM x64 for system builders,

    so if i use it to upgrade from 8 to 8.1 does it accept my serial after the installation assuming i enter the generic serial in the installation? and does it differ from my own edition of windows and do i lose anything or any info will change on the laptop using this upgrade method?

    Yes. After you have upgraded you have Windows 8.1 instead of Windows 8.

    • Installed programs, documents, pictures, music, videos, etc. are retained.
    • Not installed programs (portable programs, copied programs) you have to install again.
    • Windows system configurations are set to default values (e.g. border size of desktop windows, sort order of Windows Explorer, energy profiles, etc.).
    • Program configurations are retained (e.g. default font settings in MS Word).
