If you don’t have the required drivers installed in your computer, the hardware that you try to connect to your computer will most likely fail. In order to keep the operating system running on your computer, manufacturers develop drivers that can work harmoniously with your devices and applications. However, internet Wi-Fi connections can fail if suitable drivers are not installed. Worry not though for this post will guide you in installing Wi-Fi drivers on your Windows 10 computer. As you know, a driver is an essential piece of software designed for a specific operating system like Windows 10, Linux, and many more. The operating system uses it to communicate with other hardware devices such as printers and mice. Most hardware manufacturers feature a support page of their own product where you can look for the necessary drivers available for download. You will see that the Windows operating system has a set of drivers that are already installed and you do not have to do anything except plug in the device. So if the driver is not locally available, it will pull it down from its web server and automatically install it for you after you connect the device. However, there are instances when you might encounter some issues while using your Wi-Fi and during these times, you might have to reinstall your Wi-Fi drivers so read on as this post will provide you guidelines in installing Wi-Fi drivers in Windows 10. Refer to the steps below to do so. Step 1: First, go to your manufacturer’s website and look for the right driver you want to install to download your Wi-Fi driver. Step 2: After that, you have to download the correct Wi-Fi driver if it’s available. You have to know the exact name and version of the driver so that you can download it and this information can be found from the Device Manager. Just make sure that you have the right wireless adapter driver downloaded. Step 3: Once done, open the setup of the new driver that you’ve downloaded earlier and run the file and then follow the next on-screen instructions that appear right after. Step 4: You’re not done yet as you need to verify if you have downloaded and installed the correct Wi-Fi driver. Refer to the sub-steps below to do so:

• First, right-click on the Start button and select the Device Manager to open it.
• From there, look for the Network Adapters and expand its category to make all the network adapters visible including the wireless adapter.
• You can easily spot the wireless adapter as it has the “wireless” term in its entry.
• Next, right-click on the wireless driver entry in the Device Manager and select Network adapters, and then click on Properties to check the version number of the driver.
• Now select the Driver tab and view the details. If it looks well then it means that you have the right version of the driver installed.

As previously announced by Google feature to quickly delete the last 15min of browsing history via one button is rolling out now. For now, only Apple users will be available to use this feature but the Android update is scheduled for later this year, a strange move by Google but it is what it is. For anyone who is unfamiliar with this feature, basically, Google wants a quick way to remove the last 15min of browsing history as a supposedly stated request to make deleting browsing history much easier. Google came up with this idea so you can keep the previous history intact but remove just 15min time frame, no additional explanation was given on why 15 but I presume it is some round number that came up as the middle one with research, read telemetry info. Using quick delete requires being signed into Search with a Google account. Users can access the option by simply tapping on the avatar icon to access the settings then choosing "Delete last 15 minutes."

The previous Windows versions all came with Microsoft's browser Internet Explorer. A lot of users love it because not only that it is easy to use. It is also very fast. Users didn’t have to worry about compatibility because it is almost always compatible with its Windows Version. When they introduced Windows 10, they changed the name of the browser from Internet Explorer to Microsoft Edge. It is faster and more user-friendly compared to its predecessors. But after the Creator Update, some experienced receiving the inet_e_resource_not_found error code. In contrary to what everyone expects, you actually don’t have to uninstall and reinstall the Microsoft Edge App. What you can do is reset the browser in your Apps & Features Settings in your Microsoft Settings.

To reset the browser you can follow the steps below:

1. Click on the Windows icon and go to settings.
2. Click on Apps and this will bring you to the Apps & Features page. Look for Microsoft Edge from the list of Apps and click on it.
3. Choose Advance Option
4. Scroll down then Under Reset, click on repair or reset. When you repair it will fix the existing problem but the data that caused the problem may still be present and can still cause problems. If you click on reset, it will delete all the cache and cookies that are installed in your browser but it will save your Favorites as well as your bookmarks.

Another way to resolve this is by disabling the feature TCP Fast Open on Microsoft Edge. To disable this, go ahead and follow the steps below:

1. Open the Microsoft Edge browser.
2. Type in about: flags on the Address (URL) bar.
3. Under Networking, uncheck the Enable TCP Fast Open.
4. Close your Microsoft Edge browser and open a new one.

Flushing the DNS also worked for other Users. Sometimes, the error code the inet_e_resource_not_found is caused by a corrupted DNS cache. There are 2 ways to flush your DNS. The first option is to use the command prompt to run the command.

1. To access the Command prompt or CMD, you can search for it on Cortana or you can click on the Windows icon to access the Programs, scroll down to the Windows System folder and click on it.
2. A dropdown menu will show up, click on Command Prompt which is the first on the list.
3. Type in the code ipconfig /flushdns and press enter.
4. There will be a message that will show that says Windows IP configuration successfully flushed the DNS Resolver Cache
5. Exit the CMD by typing exit and press enter.

The easiest way to do this is to Press the keys Window + R on your keyboard. Type in ipconfig /flushdns in the search box and hit enter or click on OK. These are only some of the ways to resolve the inet_e_resource_not_found. There are other ways to further troubleshoot this issue such as reinstalling your Wifi Adapter Driver or adjusting the DNS Server Address. But most of the time, users are able to resolve the issue with the steps provided above.
