|I may be part of a new small business soon.
The plan at the moment will be to gut the innards of the existing machines, donate used parts, and rebuild with new parts.
The element I've never done before is this: Have enough legal copies of the existing windows operating system(s) so that if/when one computer goes bad, I can gut, reformat, donate, and reinstall another copy on a machine in a legal way that keeps us in good form legally and ethically, without requiring a single-copy purchase; and can do so right there and then on that very day when we need it.
A significant part of this scheme is that we will have real business computers with the apps we need. i.e., minimized crap-ware; quite possibly zero. (Every fully constructed computer that I've seen in the past ten years came preloaded with crapware, to an astounding degree.)
So, what's the stupid way to avoid, and the smart way to proceed, along the path toward...
-- Several (more than 2, less than 15) fully legal copies of windows
-- Clean computers with just the apps we want
-- Ability to reformat and reinstall on a moment's notice.
