In Hyper-V R1, you could have a maximum of 50 difference disks in a parent-child chain. This was not typically a problem unless you heavily used snapshots. Hyper-V R2 has expanded the number of supported difference disks in a chain to 1024. This should satisfy even the most heavy snapshot users.

Note the performance of the difference disk read/write has also improved. See the following whitepaper for more details

Switching a VM to Full Screen

Want to view a VM in full screen mode so it looks like it is the OS or application that is running on your machine? If you are using the VMConnect tool built into Hyper-V you would click the View menu option, then select Full Screen. You can also just press CTRL-ALT-BREAK to toggle the mode. 

Note on most laptops you will need to press CTRL-ALT-FN-BREAK because the break key requires pressing the Function key. If you do not have a key labeled BREAK, then try the key labeled PAUSE.
