Windows 10 not working

Good Afteroon ac3mark;

The upgrade I received was the one that was sent to my computer by Microsoft. I had the familiar little window appear (square made of 4 squares) on the bottom right of my task bar. Once I clicked on it, I was offered the free upgrade which was to be released July 29th. I chose to accept. On the 29th of July I checked my email and the information was there from Microsoft for me to do the download. I followed the instructions explicitly and as I said it worked well for about a week. After that first week nothing worked properly. I cannot get any results when I left click on my start menu, I cannot type in the gray box that is beside the start menu "Search the web and Windows". There is a icon on the lower right of my task bar that says "New Notifications" that when I left click it will not open. When I right click on it, I get the choices of

A.) Open Action Center
B.) Turn on Quiet Hours

I have to right click to do anything at all with my volume.

Please if you have any further questions that can help me figure out how to resolve this, do not hesitate in asking. I do not know what else to do. Thank you so much for replying to my question.

OK, I wanted to make certain we werre dealing with a valid install!
