Recently, I was asked where the best place to find a good deal on Microsoft's Windows 7 operating system would be. Having used the RC, I knew I would be upgrading so I preordered up a couple of the $50 Home Premium copies that lasted for only two weeks back in June/July 2009 (in hindsight, I wish I would have picked up a few more copies for friends & family). Since then I haven't needed to purchase individual licenses and this put me into the position of not really knowing what deals exist right now for the average person other than the assumption there were non-profit, educational, OEM, MSDN member, etc. pricing. I also knew the family pack deal was dead.
[Update 2010-09-02: The family pack is making a comeback as of October 22, 2010; no word on how long the promotion will last yet]
In the end, we saw that there are still a few inexpensive (and legal) upgrade options found in the top search results and also through our own research. Note that I am excluding the Windows Anytime Upgrades since those are for adding features to an already purchased copy of Windows 7 and also OEM pricing since that's for system builders only. Read further for our findings.
