there is windows xp retail that is running on a computer, disk is absent, windows in official with official key activated. Questions:Can it be done with a tool, similar to acer recovery tool, copy of this windows? and can it be used on any pc? (if yes, how many pc?) I have seen 1 year ago, that there can be found on the net recovery installation disk of windows, like hp or asus or dell, can they freely then be run on many pcs? no activation needed in that case? automatic windows updates must be off or on in such case?
