Only if your machine is not Enterprise (which it should be in a business) or Pro joined to a domain, which if your machine is not, it is essentially "consumer" If you have edge-case needs that that require days of uptime fork out for the right version or rent a server. Microsoft made the correct choice here: consumer versions (Home, Pro not joined to a domain) should be kept automatically updated. Don't like it? Move to linux or OS X. That's the cost of not wanting another XP.
