If you’re using Windows, go to “start” and click on “control panel.” Then go to “system” and select “99% disk cleaner.” This will run for about 10 minutes.
If you’re not using Windows, open up the start menu and find your computer’s installed programs folder. Locate your browser, find its configuration page (this varies with the browser), click preferences, security tab. On that tab is an option for cleaning out internet data or something like that which you want to uncheck then save changes. Once the tab is unselected it will ask if you still want to clean out internet data automatically displaying a box where you would click ok for confirmation.
