It was the system builder version (i.e. brown box) bought standalone. Got p155ed off with the OEM version that came with it...plus the recovery CD that originally came with it didn't like it when i changed the (dead) hard drive..sodding hidden partitions!
Need a seperate licence 
You mean not the sticker that came with it [smiley=embarassed.gif] or am i missing something?
system builder is a odd version that should only be available to authorised system builders, and additional licence is required for each use. If you are system builder, check licence requirements on your system builder portal, as there are variations:)
Same with volume versions - it will allow you to install as many as you like (activation v1.0), but you have to manually ensure you have purchased enough licences (which is why later versions of volume software come with either MAK or activation v2, both of which need activation)
