Remove Windows Genuine 'Suspect Counterfeiting'

Few minutes ago i’ve been reported by someone that want to use free hotspot in my workplace but his laptop could not connected to the hotspot. Then i see his windows being notice with message alert from Microsoft Genuine validation, that his laptop had been detected using unoriginal windows. I suggest him to re install the windows again so he got he fresh windows operating system. But i still try to help him connect to my hotspot, because outside is rainy. Then i try to restore from windows fiture restore point. First restore it didn’t work, then i see his windows is slow loading. Then i rstored it again twice for the older restore point. And i dont know how but the alert from windows genuine tools is gone, because the first restore it still appear. After the third restored the alert is dissapeared. I dont know is it work for another system or maybe i got this just for luck. But maybe you can try it, and hope it work for you too
