Hi all An icon appeared on my tray saying I needed to activate windows. When I went through the process it said it needed to validate my licence and asked me for the key, the long sequence of numbers on the original disk, etc. I bought the PC 2nd hand about 2 years ago from a PC shop and it was already on there when I got it so I have no idea what the number is. It says I have 30 days to activate it otherwise I can't use it. Can someone please give me some advice what this all means in particular will I not be able to use my PC after the 30 days is up?? Any help greatly appreciated.
