Stop window refreshing in Live Preview? I am working on LivePreview and the window it's get loaded at every change. It is possible to do that only when I will click the Save button?
No, that’s the whole point of Live Preview, to update and preview the changes “live”.

If that’s not what you want you can save the entry via “Save an continue editing” (keyboard shortcut CMD+S) and then view the changes by clicking the “Entry link” button.
