How do I start my programs after the Windows 10 Tweek updated today?

I am needing help in how to start a program - as the Windows 10 update occurred on my laptop last night.
When I left mouse click on the small Windows icon in the bottom left of my computer screen nothing pops up. Previously the Apps option would come up and I could start my programs. I also lost all my pinned programs that I used to use.
Also, my "Ask me anything" search field does not work.

I am not great at computers......

Thanks!

Has your Windows 10 Start menu stopped working? Here are four ways to fix it - BT

I was able to get the Start Menu to work by:

Check and repair corrupt Windows files - My computer didn't have any corrupt files - that I could tell after running the process in powershell.

Then after that I ran the: Reinstall Windows apps and re-started my computer. Now the Start menu works, my pinned programs show back up, my task bar on the lower right shows back up, and my date and time show back up.

And the Cortana"Ask me anything" is working! :)
