right click on the drive, select disk cleanup, click on clean up system files, check previous windows installation, click on ok, click on delete files

Sometimes you have to take ownership, delete, take ownership, delete...
First you need to take ownership.  Second, take full admin rights.  Then delete.

The first two steps are outlined in this article.

After that process, go into command prompt.  Type this command (Assuming that your Windows.old is on the root of C:)
rmdir/s/q c:\windows.old

Open in new window

 You could just delete the folder in Windows Explorer, but you may have to restart it a few times.  The command line is more effective for large jobs like this.

Just checking ... do both versions work?
If so you don't have a "windows.old" folder just a dual boot system with two Windows partitions.
Otherwise as above :)
