Hi, Ron.
As Jawade said, use Disk Management, a built-in part of every version of
Windows starting with Windows 2000. There are several ways to start it;
my favorite is to just press the Start button, type diskmgmt.msc and press
Enter. You'll need the Administrator password to get past this point.
In Disk Management, by default you should see the volume list in the top
of the window and the Graphical View at the bottom; just two ways to look
at the same information. From this window, we can manage our hard disk
partitions (and just about any other device that can be assigned a "drive"
letter, such as a CD/DVD drive, a USB flash drive, etc.). We can create
and format partitions, name them, assign and reassign letters, and do
other jobs, too. (While "partition" and "volume" are not truly
synonymous, they are often used to mean the same thing. In Disk
Management, click Help | Help Topics | Disk Management Welcome for lots of
good information that most computer users never get around to learning.)
In your case, if I understand what you've told us so far, you should see
your Drive C:, followed by the partition that held Kubuntu. That
partition may now be completely empty, but it is not yet "Free Space"
because it is still a part of that empty partition. If that's correct,
then right-click on the Kubuntu partition and click Delete Volume and
confirm that you are sure. You should then see that area as Free Space.
NOW you can right-click on Drive C: and choose Extend volume. That option
is greyed out unless the space immediately following the chosen volume is
free, but it should now be available.
If you don't see what I expect, please post back with details about what
volumes are on that hard drive.
