How I will be doing things on July 29th

Take a system image of my working 8.1 pro

Upgrade to 10 take a system image.

Recover to clean install update and install any drivers then take a system image

Install all applications and take a system image

With all these in place I can mess around with any of the install run tests on different applications and if anything goes wrong I have a choice of where to recover from. Once I am happy everything is working I can get rid of some of the images until this point I will keep everything. I will then back up my fully working windows 10 install to a couple of places so it is safe as well as keeping a local image. With this hardware then I will never need to run a clean install as can easily recover to a fully tested working system in minutes

Why only once? I do a clean install at least once a year or if replacing hardware more often.

Many others would do the same. I back up all my files though but no need for a full image.
