To delete all cookies on Microsoft Edge, click on its menu in the upper-right corner. That's three little dots. Scroll down to Settings >> under Clear Browsing Data, click on Choose What to Clear. To delete just the cookies, make sure the blue box next to Cookies is check marked. Then, click Clear.
As with Microsoft Edge, you clear cookies on its predecessor, Internet Explorer, in much the same way.
Click on the little sprocket (circle with points) on the upper-right side of your computer screen. Click on Internet Options >> under the General tab, click on Browsing History >> Delete.
If you use Safari on a Mac, here's how you delete cookies. Click on Preferences >> Privacy >> Remove All Website Data. Or click Details to select which sites and cookies you want to delete >> Remove.
Just a reminder, take your time deleting cookies. You may want to keep them for your favorite websites. If you use a site often, you might prefer the ease of getting right back to where you left off, while giving up space on your computer and some of your privacy.
