Windows 10: The number of items to be shown in the Taskbar Thumbnail peek list can be set in the...

When hovering over a pinned app in the taskbar, a set of open files is shown. When there are many, a list is shown - this is the 'peek preview list'.The number of items to be shown in the Taskbar Thumbnail peek preview list can be tweaked in the registry Taskband settings. Is there a way to sort this list on the file extensions? With 10+ files in the list, this would be quite handy to e.g. distinguish functions from tables,

How do I change Taskbar icon preview from Thumbnail peek to List peek in Win 10 v 1703?

Thanks Gil deG

That's a 90% fix.

I followed the instructions and used the option to:

"type 0 (zero) it will effectively disable taskbar thumbnail previews,
and only show in list mode."

This works, but only if there is more than one instance of an item open. So if I have only one Explorer window open the peek preview will still be thumbnail. As soon as I open a second or more Explorer
window the preview peek switches to List. Same behavior for single to multiple instances of any other program in the taskbar - It's Thumbnail for one instance, List for multiple.

So when setting the Decimal value is set to 0, it acts like Threshold value 1.

I'm using Win 10 Pro. I'm wondering if there is an equivalent way to do this using Group Policy Editor, or is it just thorugh regedit?

Thanks
