Windows 7: Win 8 confusion

Hello
I came here instead of the Windows 8 forum b/c it seemed to be more relevant to my question.
I am confused;
I read that MS is selling Win 8 Pro rt for $ 45. I think you download and save to disc.
I tried to understand which is the best way to get the appropriate version of Win 8 yet I am confused by the terms, limitations and what you actually get.
I have Win 7 Home Premium so I believe I can use the key to my Office 10 to use it with Win 8.
I think my Documents etc come with with Win 8.
I hope the rest of Win 7 comes along too.
If I want Win 8 Pro, which I think is the best, where do I go, what do I pay, and how do I do it?
Am I premature and should wait a while or should I jump on the opportunity to get the full version of Pro for less money now?
Thank you for helping me sift through this.
Peter

No
Office is onlt part of a Windows 8 RT install on devices such as the Surface.
Office is a separate product to Windows in all other cases.
The 'My Documents folders have been a part of Windows since Win95 - but are merelt a defined storage are for data, not part of Office.
If you want Windows 8, your best option is to run the Windows 8 Upgrade Assistant which will take youm through the whole process from checking your current system's ability to run Win8, which version is best for you, the purchase, download and install.

Thank you for the informtion. I woud not use the first link as I am not buying a new Win 7 but have made the second link a favorite so when the time is right I can use it - or go to a retail store.

I just ran the "Upgrade to Windows 8" over the weekend and everything worked flawlessly. Since I have a copy of Windows 7 on another disk, I used the don't keep anything setting during installation and afterward deleted the windows.old folder to save space. I ended up installing the Windows Classic Shell for convenience sake. Since Windows 8 is probably going to be the OS of the future I figured I might as well get to learn about it. But like when I first installed Windows 7, I kept a copy of Windows XP to fall back on, I will keep my copy of Windows 7 also.

Thank you for all that information which I am sure is going to come in handy.
Once you install 8 I wonder if you can put 7 in a VM?
Peter

You can - you would require a seconf Full Windows7 license to do so, though, since the original one has been subsumed into the upgrade.

Oh, I was thinking of the VM where you use XP and figured you could do the same with 7 as you already purchased it.

While I have you, could you please tell me the cost you incurred obtaining Win 8 Pro using the system to which your link refers.
I should not assume it is Pro because I do not even know the choices. I would like the one similar to Win 7 home premium.

You're thinking about XP Mode then - which was only available to Pro and Ultimate/Enterprise Windows 7.
That was a special bolt-on produced to ease the transition away from XP, due to the huge differences in the platforms, and the large installed XP population.
No-one should have been producing software specifically for XP since the end of 2006 - and almost anything that runs on Windows 7 (or Vista) will run on Win8 without a problem.

I now understand.
When I follow the link you provided what are the versions of Win 8 available and what is the cost?
I have Win 7 Home Premium and would be satisfied with a similar version of Win 8
Thank you

You'd probably be fine with standard Windows 8 (there are only two editions - std, and Pro).
Bear in mind that neither edition will play DVD's natively - both require the purchase of an add-on for such functionality.
Read the comparisons available, and use the Upgrade Assistant (you can cancel out at any time until you've paid for the upgrade!)
