Great advice above, just another thing, grab a copy of treesize from here : http://www.jam-software.com/freeware/
It will tell you what is using all the space.

This turned out to be the key. As it turns out, the half dozen movies I've got on my IPAD have chosen to save themselves on my C drive, courtesy of ITunes. They no longer live on my C drive and I now have a healthy amount of free space on my hard drive.
When I do the disk cleanup, the More Options is exercised also.
When researching use of an SSD, I found that movie play or editing is bad because of the rewrite activity. So, I've avoided doing so.
Failed Windows updates... I once saw a 80 GB disk almost full. 70 GB was in the Update folder, downloaded but failed to install, redownloading after every boot.
If that's the case, take a look at this: http://www.sevenforums.com/tutorials/307546-windows-updates-remove-outdated-updates-windows-7-a.html
I attempted to download the windows add on but, got a message that it was already on the computer.
Thanks for all the ideas and suggestions gents! I appreciate the help and expertise.
