Hi, I've got a secondhand Probook 4540s from a shop near me which sells used laptops. At the time i got it it came with Windows 7 Professional 64bit. Everything was working smoothly, then I started updating the graphics card drivers and other drivers in it (in hopes of improving perfomance) and it was around that time that windows started complaining that this version of windows is not genuine. (I think it was after i updated bios or something. or I used a non microsoft software to download microsoft updates because my microsoft update manager was not working)
From this article, we hope that the most important tool for activating Windows7 on your PC is to give you an insight into what a product key is. There are also a few online trail windows 7 that can be used to try out Windows 7, but now Windows 7 is commercially sold by Microsoft and you have to buy your true windows to get your 7 windows running properly. These keys are not commercially sold and are not working properly. You will always get extensive support from Microsoft with genuine windows to run your product and make sure that you do not encounter any problems with Windows 7 keys or other running problems.
