In one sentence, describe what the following article is about: Click the "Windows" key or the "Start" icon, then click on "Control Panel". If you are using Windows 8, you can move the mouse up to the top right-hand corner of your screen to show the "charm bar," then click on "Control Panel". Alternately, hold down the Windows key while pressing C and click on "Settings". Open the "Exceptions" tab. Un-check the program for which you want to block access to the internet. Click "OK" when prompted. The program that you deselected should no longer be able to permeate the Windows security firewall, meaning that it is effectively blocked from reaching the Internet. You should still be able to access the Internet using all other programs.
Summary: Go to the Control Panel. Open the Security Center. Open Windows Firewall settings. Open the program and try to access the Internet.

In one sentence, describe what the following article is about: Use 6 ounces/180 milliliters (6.1floz) if you are certain of the freshness of the starter. When in doubt, use a full cup of buttermilk as starter. Shake thoroughly to mix. Label the jar with the date. This should take about 24 hours. If you find it takes longer than 36 hours, the starter was no longer active (meaning that the bacteria has died). The buttermilk may or may not be tasty if it takes longer than 36 hours but it can still be used for baking. This happens because the bacteria have fermented the milk, and the lactic acid is causing the milk proteins to thicken. Refrigerate immediately.
Summary: Add a bacterial starter of 6 to 8 ounces/180-235ml of active fresh cultured buttermilk to a clean quart jar. Fill the rest of the jar with fresh milk. Screw the lid on on securely. Let the jar sit out in a warm part of the room until thickened. Check to make sure the thickened buttermilk coats the glass.

In one sentence, describe what the following article is about: A dictionary will teach you how to correctly pronounce the word and break it down for you. Go through a page of the dictionary each day. Pronounce each words slowly and carefully. Look at the breakdown of the word if you're having trouble pronouncing the word. It's also an option to go to Dictionary.com or whatever the equivalent is for the accent you're working towards. An online dictionary gives you the option to hear the word pronounced out loud for you. It's also free as long as you have access to the internet. It's even better to use a print and online dictionary simultaneously. You can keep the print dictionary with you and listen to the word spoken aloud online. Books and audiobooks can get expensive, and that's why using your local library is great. If you don't already have a library card, get one. Then, use that card to check out books on language, books in the language you're working on, and audiobooks and/or movies. This will save you money and allow you to check out new content as often as you'd like.
Summary:
Buy a pronunciation dictionary. Use an online dictionary. Check out books and audiobooks from your local library.
