Not sure how microsoft will handle this and I intend to ring them tomorrow. The spare pc is a Dell machine which came with the traditional green legitimate xp disk. I also once had the pc looked at by a local reputable pc shop for a virus and spyware problem. I also had to provide them with the accompanying xp license code for a reinstall. Anyhow-the same pc became infected again and I did the reformat etc myself. When I installed the operating system,the accompanying license details were rejected. I do not understand this as they had been previously accepted before. Does anybody know if Microsoft will issue me with a serial that works this time as I am a bit concerned that the computer shop may have continued to use the serial without permission? Some Indian bloke at Microsoft gave me another number to ring on Monday.

The first number I rang was 0800 018 8354 where I was requested to provide the Install Id along with the accompanying disk serial. Having got nowhere with this the Indian guy gave me the other phone number and the already mentioned options. I didn't actually click the activate by telephone and so I might be better off doing this tomorrow and using those phone numbers instead.These are the ones you are referring to.
