When doing technical support. People don't always have their reinstall CD, that seems reasonable... So I get an ISO of their version and edition from off of MSDN.
What files do I need to copy over from their existing installation so that Windows won't bother with reactivation?
This is not piracy, just a common technical support issue. I don't want to resort to using those pirate tools available online. I want to know how this is done cleanly.
Saying, Microsoft doesn't allow this makes me look like an idot in front of the customer. They have a legitimate complaint, how are they supposed to know they must keep the reinstall disk?
UPDATE: When the hardware changes, the OS will still deactivate like normal. They should be allowed to reinstall a copy of their OS. Not being allowed to has to be a violation of some civil code or other law...
