I am running hyperv 2008R2. Have a VHD which I want to reduce the size (not the physical but virtual size) because there is a lot of unused space in the VHD (running win2008R2).

Its a dynamically expanding disk. How do I return the free space to the physical hard drive?

Expanding a VHD is trivial, but shrinking one is another story. There is no supported way, and even un the "unsupported, but works"  category, there is no method I trust. The chances of data corruption is just too high.

You have to compact the VHD file:
1. Shutdown the virtual machine
2. If you have snapshots you need to delete them and let the VHD merge before continuing
3. Open its Hyper-V Settings from the Hyper-V Manager;
4. Go to the Hide drive section and select Edit the VHD; Run Compact

Once compact is done your VHD will have the smallest size possible considering the data on it.

Since it’s a dynamic VHD with 2008 R2 there is no need to run defrag or Precompact (as for 2003) before compacting the file.
