I found a weird issue that only occurs on my PC. When I install anything that has a product code from Microsoft(Example Street fighter IV for Windows live, microsoft Word 2007) all codes were used on my old pc, BUT they all work on my laptop! The Street Fighter thing says it can be used on ONE pc. Microsoft Word say 3 times it has been used for 4 times by now! Just wanted to share my thoughts, could there be a problem with my pc?
