Some time ago I had Windows 10 configured such that mousing over a given application in the tray would pop up full screen views of what was open. For example, I could mouse over an Excel icon and it would pop up three thumbnails, and as I moused over each thumbnail a full screen presentation of it would take over the screen. When I had the one I wanted I could click into it. Then it started not working well, which I posted here, and was shown how to enable "Peek." But Peek would sometimes work, but often when I moved off the thumbnail it would disappear altogether. So I disabled Peek and it is worse. Many suggested just using Task View, which would be great, but has the same problem. When I click on Task View I get a desktop of smaller versions of every open file, but when the mouse moves off the Task View icon they all disappear. If I move slowly off the thumbnail, sometimes they do not disappear, but it seems random. So what I am asking for is help to get rid of anything like Peek, and make Task View stick; that is, not disappear. Seems like a simple thing, but driving me nuts and there are dozens of "fixes" with a Google search.
I use small icons and classic theme and the hover is quite small (not readable but recognizable).
