How do I access User directories after a reinstall of Windows. I have the passwords but no way to access the directories.

Question

I got a Windows wont start xc0000001. This means it cant be repaired (it fails). There are two drives set up as a RAID 1 pair.
Each has a small partition (defined as the X drive) that I was able to reinstall windows 7 on. This partition was originally used for the Windows reinstall files. There was sufficient space on the X drive to reinstall Windows 7.
However, the C: drive, where the installation was originally could not be repaired and so the small partition was used successfully.
Here's the problem. All the files that are in the "C:\Users\username" are not accessible in  that it requires "Administrative privileges" which my new user account has. I have all
the passwords to the each user associated with those directories and all the sub-directories, but no way to input the passwords or username and passwords to access these files. How can I access these files/directories?
I want to copy them off the current drive (along with all the other directories like Program Files, etc.), reformat the drives (which show no errors in fdisk and other tests), reinstall Windows 7 again on C: and start to reuse the computer again.
I can access the drives thought the CMD Prompt if I insert the Windows Disk, I cannot

If you do have administrator account or an account with admin privileges you can take ownership/assign ownership of the files folders
