I am about to re-install win XP for a friend on a Time PC but after checking the licence key with Belarc and winkeyfinder I find that the key shown is different to the one on his XP sticker on the back of his box?? Which one should I use?
Companies like Time normally install hard drives in a batch, and they use their own legal Windows key; Windows is pre-activated. They attach a sticker to the case that is the unique key for that issue of Windows. So, when you do a reinstall, you should use the key that is on the label. I'd recommend always keeping a record of the installed code for posterity... it may help in any explanation to a Microsoft telephone operator should manual activation be the way forward - it's a good indication of the original source of the machine
