Can't extend windows 10 partition into unallocated space

Hi all,
Until recently, I ran a dual boot system with Ubuntu - but for business reasons, I uninstalled it (along with it's bootloader).
Anyway, I cleared up the hard drive space in the Disk Management app on windows 10,
I have about 350GB free space from Ubuntu and I cannot extend the C: partition, you can see what I mean here

I can't seem to extend my partition and whatever program I use I have to buy the full version to extend my partition,
Help!

Try MiniTool Partition wizard. It is free.
I used it several time when I was unable to "extend" the volume back to my main drive.
Windows' own diskmanagement is no better than a ground-level app for partitions.

Wow, did you literally just buy it as well? The free software won't do anything at all. The "demo" software also won't do anything at all--especially what you were trying to do. Nice advertising though guys!
