I just bought this book yesterday and have started working through it to learn what I can about HyperV. I use Powershell for quite a few things and wanted to try out the first command that I found on Page 43

New-VM –Name “TESTMACHINE” –MemoryStartupBytes 1GB –NewVHDSizeBytes 25GB –NewVHDPatch
C:\TESTMACHINE.VHDX

It looks like -NewVHDPatch should be -NewVHDPath

Yup! You are correct! We'll get the needed changes put in.

Thanks!
