I recently purchased a desktop computer with Windows 7 64 bit operating system in Spanish. I noticed that unless you have the Ultimate version, there is a steep fee to purchase the language packs. So I used a program called 'Vistalizator.' Worked like a charm and was quite simple to install and of course it is free, unless you want to give a donation.
Anyway, several months later Windows was doing its updates and it must have picked up on the fact that I have modified the program. So now I keep getting a window flash up from Microsoft stating that I am not using genuine Windows operating system.
This is the only thing that I've modified, so is there a program out there that I can run to verify this is actually the problem?
Aside from that, is there anything I can do, aside from re-installing Windows from scratch?
