Windows – How to disable middle mouse button calling Instant Viewer

mousewindowswindows 8

I am using middle mouse button to rotate 3D scene in blender.

Unfortunately, sometimes, for some reason, Windows intercepts my clicks as some gesture or may be just as single middle-click and displays me all the windows in a grid to switch between applications.

This is very annoying.

Where it can be set? How to disable this behavior? I have Microsoft mouse and it is set as

enter image description here

I.e. no any action like "show me all applications running" or something. It is set somewhere else.

I found, that parasitic function is named "Instant Viewer". How to disable uninstall Instant Viewer?
