In Microsoft Internet Explorer, the browser that comes pre-installed on most Windows computers, clearing the cache is done from the Delete Browsing History area. From here, check Temporary Internet files and website files and then click or tap Delete.
Like with other popular browsers, the fastest way to the Delete Browsing History settings is via the Ctrl+Shift+Del keyboard shortcut.
Another option is via the Tools button (the gear icon), followed by Safety and then Delete browsing history.
See How to Clear the Cache in Internet Explorer for a full set of instructions.
TIP: Internet Explorer often refers to the browser cache as temporary internet files but they're one in the same.
