Pop-ups are annoying advertisements that launch multiple windows when you are using the Internet. They advertise everything from promotions, CDs, movies to coupons. Pop-ups use system memory, slowing down your computer and reducing the stability of Internet Explorer. You can block annoying pop-ups, however, with Internet Explorer's built-in pop-up blocker. Internet Explorer also lets you temporarily disable this feature for websites that use pop-ups for legitimate purposes.
Click the Windows "Start" button, "All Programs" and then "Internet Explorer." Click the "Tools" menu located at the top of Internet Explorer, select "Pop-up Blocker" and click on "Turn on Pop-up Blocker."
Click the "Tools" menu again to configure Internet Explorer's pop-up blocker. Click "Pop-up Blocker" and then "Pop-up Blocker Settings."
Select the blocking level that you want to use. Choose from "High," Medium" or "Low." The "High" blocking level blocks all pop-ups but prevents many web pages from displaying. Select the "Medium" blocking level to block the majority of pop-ups without interfering with websites. Select the option to play a sound if you want Internet Explorer to notify you when it blocks a pop-up. Click "OK" to save these settings.
