My bro has just taken delivery of a new Evesham PC with XP SP2. On looking at the restore points that are being created, most of them are described as "Software Distribution Service 2.0". I have googled on this but none of the results give a definitive decription of what this is (most people just speculate that it is something to do with Windows Auto Update). Have searched on Microsoft and there are no references to it at all.
Can anyone shed any light (preferably with reference to a definitive source)?
