The difference between home and pro is very small these days. Hyper-V, BitLocker, and Group Policy, are basically it. You can grab a cheap OEM licence to upgrade Home to Pro very easily for far less than $200.
Wasn't it also true that the Home version can't connect to regular SMB/CIFS shares? There's a very faint bell ringing in the back of my mind about that.
Don't forget Remote Desktop.
Good shout. That and hyper-v are why I upgraded to pro (on the very cheap) on my main windows machine & laptop.
