Still need proper XP compatiility on Windows 10.
I installed proper XP mode on Windows 7, per MS it "runs in a separate window on the Windows 7 desktop, much like a program, except it's a fully-functional, fully-licensed version of Windows XP".
It's needed because half the point of owning the laptop is to look after some elderly but loved USB-adminstered gadgets. No additional XP license needed - that's important too.
Now I understand that this type of XP mode does not and will not ever exist with Windows 10.
Lack of that is the only thing preventing me to move to 10 - all the privacy issues can be mitigated by careful tweaking (I hope).
