Ha ha ha, wow...believe me, most of what this "guru" said is completely untrue. Some of it is impossible. There is nothing that Microsoft or anyone else can do to blow up your monitor, unless they open it up and plant a bomb while you're not looking. Some Microsoft products do sometimes phone home, but the situation described is horribly exaggerated. First of all, they don't get any of your personal information or...well, all that much information at all. However, if you were using an illegal copy of Windows, they would eventually find out and take steps to disable your OS, forcing you to buy a legal copy.
