Dexpot still works fine even though it hasn't been updated for years. And I love being able to have 9 virtual desktops arranged in a 3x3 grid and a semi-permanent transparent "minimap" of what's on each desktop as well as my current location in the 3x3 grid. But it has an issue which makes it unusable for me, something which may or may not be a bug, i.e. on switching to a desktop, if that desktop contains more than one window, all of them are brought to the front one after another, causing considerable delay if there are >3 windows present. The native win10 virtual desktop feature doesn't seem to have that issue.
