We have successfully installed a Windows 8 Pro Recovery ISO (created almost a year ago) to our TOSHIBA Satellite s855-5381. Everything is up and running with the exception that when checking the version, Windows version is not Professional, it's just Windows 8.
We were informed by an EE that no matter what ISO we install, the notebook has "embedded in their system firmware that the reason for setup choosing the home version, is that embedded in the system's firmware, there seems to be a key for home, setup finds and uses that key without asking".
Effectively, after the installed we extracted the product key and is different from our w8pro product key purchase with the computer.
We have download Windows 8 Professional ISO from Microsoft website (https://www.microsoft.com/en-us/software-download/windows8ISO
) using their tool on the page. Based on the the page contents it seem that the 8.1 download can be installed as home version or professional (as per EE comments previously).
To upgrade our current installation, can we use this download?
What other observations if any, should consider for this type of install?
