Ken...this response is lame! I hate Windows 8. Been trying to learn it and get comfortable with it for hours. Need a solution. It would be great on a touch screen or tablet, but that's not what I have.
Your choices as I see it with Windows 8/8.1:
Learn to use it the way it was designed. No - it is not like Windows 7. Yes - some parts of it would be easier on a touchscreen. Yes - it can be used without a touchscreen, but with a few days to a few weeks learning curve, dependent on the individual. It's not likely to go away in the next 12-18 months nor will it probably even have any drastic look/feel changes for that amount of time after 8.1's release to the public (beyond any changes 8.1 makes - which really are not going back to the XP/Vista/7 interface at all.)
Make it look/act as much like Windows 7 as possible with one of many third party applications (some free, some cost...)

You can get the Start menu back and disable some of the gestures and boot straight to the desktop with some of those. Truthfully - for most people this is more than enough. Sure, there are the people who say, "why should I have to run a third party application to make my OS more usable" but then again - they do it already most likely. They may use an alternative web browser, some office suite, some video editing application, some image editing application, some audio player or editor, various antivirus and antimalware applications, etc. All those are changing the way they interact with the OS. Maybe not at the look/feel level - but the Linux crowd has been doing it for years and the Windows crowd has always had a subset of people who modify their desktop layout to extremes. *shrug*
Install a different operating system on the computer you have *given* the manufacturer of said computer or the manufacturers of the individual components in said computer have drivers for the different operating system. If you have Windows 8 Pro and you happen to have a legitimate license for Windows 7 Professional - it can be a no-cost (other than time and effort) venture. If you have a full unused license [never used if OEM, not used currently if retail] of any other version of Windows (likely Windows 7 would be the best choice for the age of the hardware and staying not so far behind the curve) - you can use it to do your install with the caveat already mentioned about hardware support. You can use one of many flavors of linux, same caveat about the hardware drivers apply but add the functionality being probably almost as foreign to most as Windows 8 is - ikely more considering a lot of things you are used to just won't exist in the way you have gotten used to them, if at all.
Return the product, make sure it is well known and documented to those you return it to as well as the manufacturer of the product as a whole WHY you returned it. Who knows - they might even offer to downgrade to Windows 7 for you (unlikely, but not unheard of.) If that doesn't happen (more likely) you can look around and get a new or recently refurbished/off-lease Windows 7 system probably for less money than you spent on the Windows 8 system (if it was a whole system and not just a software upgrade.)
If all you did was purchase the Windows 8 upgrade and installed it on your current system with an older Windows OS - return Windows 8 for a full refund and restore your system to prior OS. There's not PUSH to move to Windows 8/8.1 - certainly very few (if any) software vendors require it for the major "non-Windows Store" applications they make and I have not found many peripherals (none actually) that require Windows 8 to work. However, you have to do this one quick. As you stated your attempt has only been "for hours", you may still be okay. It's like 30 days or something?
