2. Now the next step open run (press windowskeyboard + R and type ncpa.cpl). When window pop up, right click your connection and choose properties.(see picture)

3. A connection window now will pop up. Click configure button.

mine was using a Local Area Connection, this depend on which connection you use (e.g: wireless connection).

4. Again… 😛 another window will pop up about the adapter properties. Click the advanced tab.

click OK when you finished.

5. To check the changes, open the command promptand check the new MAC address by typing ipconfig /all.

That's it!

And that's how easy it is for hackers to see and record every keystroke you press on your computer. When a hacker has an unnoticed backdoor on your computer, anything is possible, but there are a few things you can do to minimize the risk of having your keys captured:

🔸Use antivirus software. While there's not a catch-all solution, and antivirus software won't protect against sophisticated and cutting-edge keyloggers, there's still no excuse for not using antivirus software which protects against most known keylogger software.

🔸Use on-screen keyboards when entering passwords.One of the limitations of most keyloggers is that they only capture actual keystrokes being pressed on the keyboard. The Windows on-screen keyboard will provide a virtual keyboard that may help circumvent keyloggers.

🔸Use a firewall. It's possible lazy attackers won't go through the effort of disguising their payloads to appear as being normal DNS (port 53) or HTTP (port 80) transmissions. A firewall might catch suspicious packets leaving your computer on port 35357.

🔸Protect your computer against backdoors. While all of the above is helpful when you're already backdoored, the best thing to do is make sure you're not exploited in the first place.

1. See what's sucking the most juice. Navigate to Settings > Battery to see an organized breakdown of what's consuming your phone's battery. Applications and features will display in a descending list of battery hogs. If you see an application you barely use or a feature you never use, you'll want to uninstall the app or turn off the feature.

2. Reduce email, Twitter, and Facebook polling.
 Set your various messaging apps to "manual" for the polling or refresh frequency, just as a test, and you'll instantly extend your device's battery life by a significant amount. Once you see what a difference that makes, try re-enabling just the most important ones, and possibly reducing their polling frequency in the process.

3. Turn unnecessary hardware radios off.
 It's great that today's phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE. On stock Android, swipe down to bring up the Notification bar, and then tap the icon on the top right corner.

4. Use the extra power saving mode if you have it.
 The aforementioned Galaxy S5 and HTC One (M8) both have Ultra Power Saving and Extreme Power Saving modes, respectively, that limits the phone to texting, phone calls, Web browsing, and Facebook. This can squeeze extra hours or even a day of standby time out of just a few remaining percentage points of battery.

5. Trim apps running in the background.
 From Settings > Apps, swipe to the left; you'll see a list of apps that are currently running. Tap on each one to see what they're for; you can stop any apps that you don't need running in the background all of the time.

6. Dump unnecessary home screen widgets and live wallpaper.
 Just because they're sitting on the home screen, seemingly inactive, doesn't mean they're not consuming power. This goes for widgets that poll status updates in the background, as well as ones that just sit there but look pretty and animated—not to mention animated live wallpaper. (But don't dump everything, as part of what makes Android great are the home screen customizations; just remove the ones you don't use.)

7. Turn down the brightness and turn off Automatic Brightness.
 It's probably obvious at this point, but you'll be surprised by how much this one alone helps to improve battery life.

8. Update your apps.
Applications often get updated to use less battery power, so you should make sure your apps are up to date. Even if you configured the phone for automatic updates, some apps still require that you manually install updates. Check for app updates in Google Play by hitting the menu key and going to My Apps.

9. Keep an eye on signal strength.
 If you're in an area with poor cellular coverage, the phone will work harder to latch onto a strong-enough signal. This has an adverse effect on battery life. There's not much you can do about this one, but keep in mind that this could be the culprit behind a seemingly weak battery; it's worth popping the phone into Airplane mode if you don't need data or voice calls.

10. Check the reviews.
 We conduct battery life tests on every single Android phone we review. Unsurprisingly, the results vary widely between handsets, even on the same network. When choosing a phone, make sure that real world talk time is sufficient. You can't go by what the manufacturer says; we see variances on the order of several hours of usage in both directions on a regular basis.

⬛️How to Check your IP information⬛️



 🦠You might need your PC's IP address if you want to set up an Internet connection, allow other people to connect to your PC, or need to troubleshoot network problems.
