Yesterday I suddenly got a "You are running an illegal Windows copy" alert popping up. But the thing is that the Windows 7 version I`m running came with the PC three years ago, so how can it suddenly be illegal now? I did delete some useless microsoft files and folders a few days ago, but normally if you try to delete files you need, Windows stops you. My question is whether deleting OS stuff you never use can cause the copy you already paid for years ago to become "illegal"? If so then I am questioning the legality of that claim, since it sounds a lot like fraud. Or maybe it`s Microsoft`s way of telling me to switch to Linux...Either way I`m not paying a dime for something I already own. PS: Just to be absolutely clear: I am not running a cracked Windows 7, but the OS that came with my PC at the store.
