To clear the cache in Microsoft Edge, open Edge, click the button with three horizontal dots in the upper-right corner of the browser window, and select Settings from the resulting drop-down menu. This action will cause a slide out menu to open from the right side of the browser.
Once the menu has popped out, click on the heading under General titled Privacy & Security. Afterwards, click on the the button Choose what to clear and select the first 4 items on the list: Browsing history, Cookies and saved website data, Cached data and files, Tabs I've set aside or recently closed. Once the boxes have been checked, click on the button Clear and wait while the browser clears out that data.
