I wasn’t trying to disable it. I wanted to move it off my puny OS drive SSD to a huge spin drive. It fought me tooth and nail even though it has a move button. I tried many ways including regedit until I finally gave up and turned it off.

The worst part was when I was trying to manually copy the files and it kept telling me I needed do purchase more cloud storage – to do a local file copy!

I concluded this obstinance was by design to sell more product. Especially after using Steam to shuffle some of my games around later that same day. Their software is wonderful now!
