Not Authorized to Delete Old Files

I'm trying to delete a file the system named "WindowsDV7. old".  It was created after I upgrade to Win 8 Pro.  That was over a year ago.  I think its safe to delete the folder, and free up space.  However,  I'm getting blocked by Win 8. System states I need approval from "System".  I'm the only Administrator, and sole user with access to the laptop.  What do I need to do to resolve issue?

You will probably need to take ownership of the folder first before you will be allowed to delete it.  The permissions are attached from the old OS install more than likely.

See this Microsoft TechNet article on how to take ownership of folders:

I thought it was always called [Windows.old], not [WindowsDV7.old], but in any case, see if this MS article helps:

Can you try. Right click on that file-> properties->security->edit

you can give full control to your account and apply .Then delete the file.

Thank you.
