One more tip for improving performance of Virtual PC.

In an article titled Tuning Virtual PC Performance on, I described some tips for improving the performance of Virtual PC. Here's stilll another tip for you:

  1. Start your virtual machine (VM).
  2. Defragment the drive within the VM.
  3. Select CD --> Capture ISO Image --> browse to C:/Program Files/Microsoft Virtual PC/Virtual Machine Additions/ --> select Virtual Disk Precompactor.iso --> OK --> Yes
  4. Once pre-compacting is complete, select CD --> Release ISO Image, and then shut down your VM.
  5. Finally, in the Virtual PC console, select File --> Virtual Disk Wizard --> Next --> Edit an existing virtual disk --> browse to your .vhd --> Next --> Compact it --> Replace the original file --> Next --> Finish --> go for coffee :-)
