Traps for young Players

Experience - Getting the test before the lesson sucks.

Note to all (although this may appear obvious as you read), when you have a single copy of a windows licence key to use, and you are trying to run multiple instances of that licence via differencing VHD's, ensure to Activate the master VHD from the physical hardware, ie boot it up, as you will your differenced disks.

Otherwise as the differencing disks are run on different (physical vs virtual) hardware, your previous activation is ignored, and future attempts at activation will fail dismally.

Bugger.
