You can access the Device Manager from the Control Panel. It will be located in the System and Security section if you are using Category View. In your Device Manager, you will see a list of all of the hardware installed on your computer. These are sorted into categories. Expand the Network Adapters section to see all of your installed network adapters. If you are not sure which adapter you are using, see Step 1 of the second method to find your device's Description. Select Properties from the menu to open the network adapter's Properties window. Look for the "Network Address" or "Locally Administered Address" entry. Highlight it and you will see a "Value" field on the right. Click the radio button to enable the "Value" field. Not all adapters can be changed this way. If you can't find either of these entries, you will need to use one of the other methods in this article. MAC addresses are 12-digit values, and should be entered without any dashes or colons. For example, if you want to make the MAC address "2A:1B:4C:3D:6E:5F", you would enter "2A1B4C3D6E5F". You can also disable and re-enable your adapter within Windows for the change to become effective without rebooting. Just sliding the Wi-Fi's On/Off switch like the slider found on ThinkPads and VaiOs won't satisfactorily disable/re-enable the card. Once you've rebooted the computer, open the Command Prompt and enter ipconfig /all and note the Physical Address of your adapter. It should be your new MAC address.

Summary: Open the Device Manager. Expand the Network Adapters section. Right-click on your adapter. Click the Advanced tab. Enter your new MAC address. Reboot your computer to enable the changes. Check that the changes took effect.


Measure 4 teaspoons (15 g) of black peppercorns into a mortar. Use a pestle to crack the peppercorns until they're slightly crushed and aromatic. If you don't have a mortar and pestle, you can put the peppercorns in a seal able plastic bag. Hit the peppercorns in the bag with a rolling pin until they're slightly crushed. Place 2 1/2 tablespoons (35 g) of butter in a small saucepan and turn the heat to low. Stir 4 1/2 tablespoons (35 g) of flour into the melted butter. Keep stirring and cooking the roux mixture until the flour is absorbed. Stir and cook the roux over low heat for 2 minutes. The roux should become thick and pasty. Pour 1 tablespoon (15 ml) of brandy into the roux and stir it until the liquid is absorbed. The alcohol in the brandy will cook off. Measure 3/4 cup plus 4 teaspoons (200 ml) of milk and slowly pour it in while you whisk the mixture. Keep whisking to prevent the sauce from becoming lumpy. Once the sauce is smooth, stir in 1/3 cup plus 4 teaspoons (100 ml) of chicken or vegetable stock. Stir in the crushed black peppercorns. Taste the sauce and add as much salt as you like. You can serve the hot sauce over your favorite meal or continue to simmer it to make a very thick sauce or gravy. You can store the leftover peppercorn sauce in an airtight container in the refrigerator for 1 to 2 days.

Summary: Crush the black peppercorns. Melt the butter and stir in the flour. Cook the roux for 2 minutes. Stir in the brandy. Whisk in the milk. Stir in the chicken stock and peppercorns. Season and serve the sauce.


In a small bowl, add 2–3 tablespoon (29.6–44.4 ml) of baking soda. Add lemon juice a few drops at a time, stirring until the mixture forms into a paste. The baking soda will act to remove surface stains while the lemon juice will whiten teeth. Wipe saliva off of your teeth with a paper towel. Apply the paste generously to dry teeth with a toothbrush and let it sit. Make sure it covers all of your teeth, and avoid swallowing any of the mixture. Let the paste sit on your teeth for one minute, timing it with your phone or a stopwatch. Rinse your mouth immediately to prevent the acidity of the lemon juice from harming your tooth enamel. Be sure that the paste is entirely removed from your teeth. As a milder alternative, use water to make the paste instead of lemon juice. Mix the paste the same way, using the same quantities of baking soda and liquid. Leave the paste on for three minutes instead of one as the milder mixture will not be acidic enough to harm enamel.

Summary: Mix together baking soda and lemon juice. Apply the paste. Leave it on for one minute, then rinse. Use water instead of lemon juice as an alternative.


College campuses are full of official and non-official groups and organizations. Some may be political, others for shared hobbies, others to create a “home away from home” for minorities and marginalized students. Joining clubs can help you continue to explore your identity, while building up a social network.  Do you feel out of place? You might look for a group that will offer support, fellowship, and solidarity, like organizations for First Generation College Students, for minorities on campus, or for international students. Do you feel spiritually adrift? There are very often faith-based or explicitly secular groups that cater to these feelings, as well, like Catholic, Atheist, Muslim, Jewish, Buddhist, and Freethinker groups. You can also find groups whose purpose is public service. If you are searching for bigger meaning in life, you might consider joining a volunteer organization that tutors at-risk high schoolers, for example, or that does community outreach. Another way that you can explore your identity – and also make a difference in society – is to get involved in causes on campus. Especially these days, college campuses are centers for activism. Joining one of these causes can give you a sense of mission and also connect you to like-minded people.  Do you want to explore your political, sexual, gender, or racial identity? Campus activist groups are usually oriented towards promoting social or political causes that can deal with these topics. Activism can also take different forms. You might join a group that promotes causes you feel strongly about, for instance, like LGBTQ awareness or Black Lives Matter. You might also get involved in demonstrations, letter writing campaigns, or campus politics. It's perfectly natural to feel closer to people like you, people who look, think, and identify like you. It's also perfectly OK to socialize with these peers. Still, one of the great things about college is the diversity of the student body in backgrounds, views, and identities. Don't be afraid to gravitate toward people like you, but avoid too much “self-segregation.”  Self-segregation is something that all groups do on college campuses to some degree. In fact, white students lead all other groups in only associating with people like them.  Try to be more aware of who you socialize with, for one. Take a look at your friends and peers. Do all of them look like you, think like you, and share the same opinions? You might be self-segregating a bit too much. Make an effort to connect with people who aren't necessarily like you. This can mean in background or appearance, but also in beliefs, worldviews, and political opinions. You won't grow as a person if you live in a self-contained echo-chamber.
Summary: Join a campus club. Get involved in causes. Socialize with peers, but don't isolate yourself.
