Removing previous OS files

Specs: Microsoft Windows XP Professional, 1.396 GHz / 503 MB
I upgraded the OS from XP Home edition to XP Professional edition by creating a new directory on my hard drive for the new system.The laptop runs just fine.

I now wish to clean my hard drive by deleting all files in the no-longer-used c:\Windows directory. I am not able to view the contents in Windows Explorer, and a Delete command does not work as it says accesss is denied to c:\Windows\systerm32\Zyzxdo.dll.

How can I completely remove c:\Windows?

I use DustBuster, just install & let it run, Italian is used, but by watching the windows, you can get the gist of how much is removed. Alternatively, you can make a note of your HD size before & after.

You said you created a new directory for installation of XP Pro.
Is that "new directory" a separate partition?

Do you get a dualboot prompt when starting up to select which XP you want to boot?

I must advise caution if you choose to follow advice in response 1. I would not install & run a foreign language "cleanup" program on an English language system, nor would I run any prog without a good understanding of the control instructions. "Italian is used, but by watching the windows, you can get the gist of how much is removed"

How dangerous is this unless you know exactly WHAT is being removed, not just how much.

Now to specifics. If you have created a dualboot with new windows in say D,E or some other partition you should know that the bootfiles for this are still written to your C drive so you cannot simply wipe the C drive without hosing your entire system.

Next, any/all programs that you previously installed in XP Home will cease to function if you wipe the C drive.

Answer the question first. Did you create a dualboot? Is XP Pro installed in it's own partition or is it in a separate file/directory of the C drive?

Thank you both for your replies. Yes, XP Pro was installed in a separate file/directory of the C drive.

Since my original post, I found other messages that encouraged me to (a). take ownership of the file in question and change the security settings, and (b). delete the file in Safe Boot mode.

Both efforts worked, and my hard drive now is completely free of the former C:\Windows directory, and I recovered an enormous amount of free space. I couldn't be happier.
