I have VirtualPC running in Win7 64bit. it's hosting a Windows XP vm. it's running out of free disk space so I increased the the vhd size using VHD Resizer however the free disk space didn't change.
I followed the step from this question where I attached the vhd file to Disk Management. However the Expand Volume option is disabled. I see about 15GB in unallocated volume. I am not sure where this is coming from. The vhd size I chose in resizer was 1.6GB.
The vhd is dynamic so I don't know why it's not expanding when it needs to. When I shose settings in the vpc, it offered an option to make it fixed size. I am expecting an option to make it bigger although.
