I have recently installed Windows 10 and downloaded a huge file just this morning. Whenever I right-click by means of my mouse it takes forever and it invariably freezes my computer, which means shutting the thing down and restarting it again. It happens when I right-click my desktop and when I browse 'my documents'. The Task Manger [if I can get it to start] tells me that Windows Explorer is not working. How can I right-click without any trouble, just like Windows 7.
