How do I clear my Edge browser cache?

Click on the Menu button in the upper right corner, then click on 'settings':

In the next menu, click on the 'privacy and security' tab, then click on 'choose what to clear':

Leave the check boxes as they are, and then click 'clear'

If you want to check more boxes and clear out your saved passwords and auto-fill data, for example, you may, but this is usually not necessary to fix most cache related issues. 

It's a good idea to clear out this data every few weeks!
