Revert Back to RC from 7 ultimate install?

I recently installed windows 7 ultimate (x86) over windows 7 RC(x64). The install worked fine however i mistakenly thought it was upgrading not installing over (x64). Long story short im left with windows.old and windows.old.000. i'd like to revert back to the rc for the time being becuase i dont have all of the software to install on the fresh os. is there any way to do this? i found the microsoft article: How to back up or transfer your data on a Windows-based computer
it however is dealing with 32bit and not the 64 (two sets of program files ect.) so im not sure how to procede without FUBARing my os. Is there a way to VMware my old os? or partition it and boot from it?
Thanks

How to restore a Windows 7-based computer to a previous Windows installation by using the Windows.old folder

Suggest that you first use Win7 backup center to save externally a Win7 backup image so you don't have to reinstall in the future, just reimage from the DVD Repair console in 15 minutes.

But what about the second file windows.old.000 there are two sets of windows old files what do i rename them?

Suggest you only deal with the windows.old folder that has your complete set of RC files in it, which would include all of your User accounts folders, windows, program files, etc.

Anyone else know for sure?

windows.old contains the program files for what looks like the 32bit programs and the windows.old.000 contains the installs for the 64 bit.

would it be possible to copy them into another partition and just boot that? and the windows.old/windows and windows.old.000/windows do not have the same content are there two sets of windows files onthe 64bit?

here are some screenshots
