I have just taken delivery of a batch of pcs that I was assured would be preloaded with xp pro. On closer inspection they have vista business installed. The supplier tells me that there is an agreement in place the allows uk schools to downgrade to xp regardless of what the rest of the world is being forced to do. I can find nothing to confirm this. Can anyone tell me if this is so and what the procedure for obtaining xp licence keys to do the install is?
