£70 for a reinstall? How does that work with licences?
E.g. Mr X brings laptop in with Windows 7. Do you use the same key and a new image?
key is on the machine (usually) so new clean image + the key that's on the laptop.. 30mins later fire up driverpacks, bang in the key from the laptop and copy their docs etc back...
(I usually take an image of the original hdd assuming its not faulty so there is no chance of anything getting lost)
