Hi! A few days ago i got a new OS win7, i was surfing the web and closed my browser down and looked down corner and it was not genuine anymore and had 3 days to activate.. ? I have used the removeWAT.. everything was fine in the start, had also unchecked the KB971033 BUT it apparently checked it self again and installed.. so i uninstalled and hide it instead.. then few days later the problem above started.. i search the web for answers and found out that i could preform a "sfc/ scannow" to see if anything is messed up in the critical system folders.. it completed the scan 100% and detected a minor error.. but was able to repair by it's self.. but the genuine watermark was still in the corner.. So i went on preparing to do a full clean up with MBRK.. I opened up the system overview to write down my key.. In the keys it says OEM? I have read that those keys should be for manufactured pc and laptops, correct me if i'm wrong.. i have a home build pc..? Then..! The must weird thing happens after i close down the system-overview window.. suddenly the genuine mark was magically disappeared... ?? And i haven't done anything els then the sfc/ scanow?? Can some body plz help me..?
