GENUINE - being the key word here. It is patched and hacked into a suspended period of time - Trial Version. Certainly gives the appearance of genuine version - but an upgrade patch from MS could end that in a blink of an eye. Genuine - NO. Pretend Genuine - YES.
No - unless you buy your version and get a GENUINE key, it will always be a "simulated genuine version"... Your question was "How do I know EXACTLY if my OS is GENUINE"..... using cracks and patches you have to realise that nothing is for certain. You could be lucky and enjoy a life time of uninterupted Win7 pleasure... or you could have your balls ripped off at the next update. Its a game of Russian Roulette.... just hope the bullet doesn't fall into the chamber next.
Does a "simulated genuine version", I meant activated version, Can the version get automatic update news from MS?
All Windows 7 Genuine and Non-Genuine will get updates, you do not need to be activated. Even stolen pirated versions are guaranteed access to updates from Microsoft. It was announced in the press back in July. Activation merely prevents an annoying pop up window every reboot and and some minor desktop GUI changes (black background, watermark), it does nothing else.
