I used another neat program that runs in Windows called WinDirStat to do a final clean up. You can delete unwanted non-OS data with WE. Take a look at the HDD contents with Windows Explorer. When you think you have removed all of the "undeletable" files and folders you "might" be done.

Select the HDD you want to work on and start deleting. After the program has loaded, click on the "Explorer" icon. When the pc starts to boot up, press the ESC key (or f10 key) repeatedly to enter the BIOS. Insert the CD created above into the CD tray and close it. While you are there, delete any other unwanted folders and files. Open it, navigate to the correct HDD and delete all the files and folders related to the OS. Among many other things, PM has a "Windows Explorer" like feature. Here's the short procedure: Download the PM program, save it, and burn it to a CD. The PM program gets loaded via a CD on power-up, before Windows boots, so Windows cannot invoke it's rules against deleting System Files. So, I used a program called "PartedMagic".

I tried several ways of changing permissions and none of them worked for me. The running Windows OS would not let me delete the system files. I installed the HDD in the second bay of my laptop (it could be left outside and connected via a USB port) and tried to delete the OS files with Windows Explorer. I had to clean out all the OS-related files and folders from this HDD and leave my existing data files intact. I plan to use the original HDD in the second bay of my laptop for data files. I installed a new solid state drive (SSD) pre-loaded with Win 7 Home Edition OS and my program files in the primary bay of my laptop.
