I doubt that there is anyone who unequivocally loves everything about any operating system they use, and that's certainly true for me.
Windows 10 has some pluses and minuses on the apps front, and I'm sure some of us would like to use alternatives (and those alternatives are probably more like what we were used to in Windows 7 or earlier).
As an example, I am really not wild about the Win10 Photos app. It is painfully slow to open up when I double click on a photo and that's the main reason I don't like it. I'm also not wild about the whole look and feel.
I would love to use something that has a look and feel that's more akin to the old Windows picture preview feature which was simple, clean, and very fast when all I wanted to do was to take a quick run through a group of pictures in a folder (or even just get a closer look at one). Proposals, anyone?
Perhaps this thread can serve as a repository for alternatives people have found to specific Win10 Apps that they don't like and for which they've found alternatives that are more to their liking.
