Yes, OS is fully genuine Win7. I have even run "sfc" - no issues with system files were detected. 
2 Frozen - the problem did not appear immediately and in full color. And I even tried to unplug the mouse! But the problem with Labview still existed so I attached it back. But I did not restart laptop that time.. 
Only when a "second" problem with Explorer appeared, I started to assume it can be a mouse or its driver. First the problem appeared only with hotkeys and only in Labview.
Upgrade! Win7 is a decade old.
