I just extended a C: drive from 40GB to 160GB with the VMware vCenter Converter Standalone and the disk keeps showing as 40GB.  However, in Windows Disk Management shows as 160GB (see pic). I already tried rescan, etc. Any ideas?

In diskmanagement shring the disk by about 10MB. Windows usually wants a little free, unpartitioned space to properly reflect the partition's size.

Use the extend filesystem command in diskpart, instructions are in the "more information" section of http://support.microsoft.com/kb/832316

rindi,
The shrink won't allow me to do it.  The Shrink button stays grayed out.

Andrew,
The virtual machine version I choose was 10.  Would that make a difference?

Maybe run a defrag as the image you posted suggests you to do.

You'd think MS would have built a re-check into the extend volume option of diskpart and the GUI so that if it failed like it has for you it would automatically re-do the extend filesystem for you. I wouldn't run a defrag until you extend the filesystem with diskpart.

Virtual Machine selection should not cause this issue, but I would recommend version 8.0, unless you need the features of v10.

To be honest, I would try again...

You can always try allocating a bit more space with VMware then extending the partition again but the extend filesystem option normally fixes this problem. (you don't mention if you have tried it or not even though I have mentioned it twice).

andyalder,

Third time's a charm, sir.
I followed the steps on the More Information section and now I have the extra space.

I must admit, I'm a bit disappointed on the Converter.

It's not a VMware problem, NTFS.SYS is to blame. It happens on physical Windows servers as well.
