2. In the search results menu that appears, right-click on Task Manager
and in the menu that appears, select "Run as administrator".

3. In the Task Manager window that appears, select the [App history] tab.
4. Near the top of the [App history] tab click on link "Delete usage history"
Usage statistics for all apps goes to zero.
