Windows Disk Management.

I have Windows 10, the C: drive total size shows 20 GB, but when I open Disk Management I see 2 partitions 10GB and 20 GB.
How can I put them all together 30 GB.  The Extend Volume is Greyed Out.

Thank you

I would use GParted to move the C: drive to the beginning of the volume and then extend it to use the rest of the disk.
See http://gparted.org.

the short answer ISO would suggest you bavkup your data and reinstall.
This an install error
Usually thefirst partition should be 500mb or 1Gb at most.
Boot the system, use disarted or gparted to shrink the 10Gb partition down, shift the second partition left, then expand its size.

Is this a VM?

Also.... if you want to look at what is on that partition, right-click on it and assign a drive letter.  arnold is very likely correct, both in the assessment of how it happened (partition was created too large during installation) and how to resolve it (shrink, don't delete, the first partition, then expand the second one).

Lastly, 30G is VERY small for Windows 10.  I'd look at replacing it with a 240G SSD (about $35).  When you copy it over, most programs will allow you to adjust the partition sizes.  This should have very little risk as you'll not be making changes to the original drive.

I agree with the CompProbSolv's  comment 30 GB is way to small. My windows folder is by itself 24.2GB.. The edition upgrades every 6 months will run out of room. Is this a windows 2 go USB drive?

how can I extend C: drive partition.. I tried to extend  hard disk from Vmware side, but when I went to disk Management, I found that It has just created separate partition...I want to make C: drive 30 GB and as one partition.

"I want to make C: drive 30 GB and as one partition."  I don't think that's possible with Windows 10.  There may be some way to do it, but it's not at all standard.  You'd be better off following the usual process of having the small first partition and the rest in the other partition.  Either reinstall from scratch or use the recommendations from others above about resizing the partitions.

Did you partition the risk prior to install?
I think it was a typo that led to this type of split.

If you just pointed the win10 installer at the unallocated space, the installer would do what needs to be done.
I.e. If you deleted both partitions and reinstall.

Though you might want to use this opportunity to test things out.
Boot from the CD get into the repair option.
Use cmd, open diskpart
List disk
Select disk 0
List partition
Select partition 1
Resize/shrink
List partition
Select the other partition and see if you can move it left.
The partition has to be to the left of the free space (free space ontheright into which te partition can be expanded)

How you got a 20GB disk to begin with I have no idea.  If you had imported the .ovf into Vmware Workstation the disk should have been 127GB with an actual size of 36GB the original vmdk is 18GB.. Even expanding it to 150GB too a long time on my system while it created the temporary disk and moved the data over. https://youtu.be/nWIoMapBodE

As the others have said (in various ways) you need to have a raw disk that is much bigger than 30GB to start with (say at least 100GB)
Then install your system from scratch

Just curious.... how did you find Partition Wizard to be a better choice than gparted?
