Roll your own PC
First, the bad news: The deadline has passed for buying standalone, boxed OEM copies of Windows 7. Everyday folks simply can't get them from Microsoft anymore.
Now, the good news: E-tailers apparently stockpiled Windows 7 licenses by the bucketful before Microsoft cut off access. Finding boxed copies of Windows 7 online is dead simple. Even better, Windows 7 Home Premium still sells for its recommended $100 MSRP. Unlike hardware pre-stuffed with Windows 7, there's been no price inflation on the software front.
Considering that you can still find boxed copies of Windows XP online, expect to see Windows 7 on sale for awhile, though its cost is sure to creep up as availability dwindles over time. Just be sure to confirm what you're buying. Some third-party sellers offer "open box" copies of Microsoft's operating system. Steer clear of those.
While despondent Windows 8 owners can install a fresh copy of Windows 7 on their PCs, this option is more likely to appeal to folks cobbling together a DIY computer from the power supply on up.

Downgrade Windows 8 Pro
If you've already purchased or built a Windows 8 Pro computer and found you loathe Live Tiles, all is not lost. Microsoft's rarely invoked downgrade rights can be tapped to transmogrify your PC into a Windows 7 Professional system.
Downgrade rights are a tricky beast, however.
You'll need to have Windows 8 Pro installed, and your PC must have run on Windows 8 Pro from the get-go—basic Windows 8 installations upgraded to Windows 8 Pro after the fact don't get downgrade rights. You'll also need a product key and an installation disc for Windows 7, which Microsoft and most PC makers will not help with. (Good thing you can still buy boxed copies of Windows 7 on sale!) Oh yeah, the process requires jumping through some complicated hoops. And did I mention that some PC builders refuse to support boxed consumer computers that have been downgraded to Windows 7?
Yes, there's a reason downgrade rights are typically used by big businesses alone. (Though businesses tend to use Windows 7 rather than Windows 8, but I digress.)
Nevertheless, downgrading has its upsides over simply nuking Windows 8 and installing a fresh copy of Windows 7. Namely, you can upgrade back to Windows 8 at no cost if you change your mind in the future. Like I said earlier: If you're on the market for a new PC, buying a computer that already has Windows 7 Professional pre-installed using Windows 8 Pro's downgrade rights essentially lets you have your cake and eat it too. Those systems are out there.
