My friend your being augmentative, it does not take 5 minutes to set-up a system with Vista, if your setting a system for a friend that doesn't even know how to install an operating system then you have to also make sure the system is fully updated, drivers and security software installed at the very least, otherwise that machine is coming straight back to you, and can't just dump a freshly installed OS on a system and pass it over to a computer illiterate person (friend or otherwise) and expect everything to be OK, even when the system has a restore option there is usually work that still needs doing once the system is restored due to it restoring back to an out of date state that is unfit for internet usage and has out of date drivers that may not work with the costumers current gear, also don't forget 99% of the time you also have to back-up their work.
