I work in the Laboratory Department and there are six divisions.There is one pc in the clinical lab …A staff who surf the net runs the Windows Update almost everyday.Until one day, the pc accidentally installs the Windows Genuine Advantage Validation Update…the desktop wallpaper disappeared and then the whole screen blackouts.There are several standard windows programme have malfunctioned.The Windows in the pc failed the genuine validation set by Microsoft Corporation.The funny thing is there was a Genuine Windows sticker attached to the desktop tower.I think the buyer got cheated by the vendor ! The vendor installed a pirated Windows software.If  anybody were to reformat the pc and install a pirated Windows again,the same blackout will appear again…
