So i have this problem, after googling it, saw many ppl encountering the same but no solution.
I bought a Toshiba laptop abroad, brought it home and it works perfectly, came with windows 8.
Later i bought a local version of the same OS, Windows 8 home. It installed and worked perfectly, updates and everything.
But when i accepted the Micrsoft "offer" to upgrade to 8.1 it took like an hour and at the end i was greeted by a message that my key is invalid. From what i've read from forums so far, this is a bug / feature (depens on point of view) that "ties" the motherboard's serial number to a certain windows key/version and that's what preventing the 8.1 upgrade.
I tried to obtain help from the shop where i bought the local version but got an answer that it's a known Microsoft problem with no solution so far. From what i read on other forums, people tried to get help from laptop manufacturer and were sent to Microsoft, which sent them back to laptop manufacturer so I didn't even try contacting them.
I wasn't very conerned about the upgrade until yesterday, when i read that only Windows 7 SP1 and 8.1 will be eligible for the Windows 10 free upgrade.
Any help is appreciated, i've tried upgarding 3 times and had to do a complete system recovery to get my laptop working again.
