Had a machine that has True Image Home 10.  I made a W7 image and then did an in place upgrade of Windows 10.  I made an image of W10 and reverted back using Acronis with no problem.  I'm keeping the machine on W7 since I use XP mode for my old Canon scanner to work.  I posted in a previous thread that my W7Pro OEMs were converted to W10 Pro Retail.  I can't really upgrade the machine but you never know when you need that extra OS license.
 
 My recent builds have True Image 2016. I hate the dumbed down GUIs.
