Users are given the option to block both inbound and outbound traffic for any apps on their computers. However, this kind of option can often lead to not being able to access the internet. In such cases, when you try to run the Windows Firewall Troubleshooter or the Windows Network Diagnostic troubleshooter, it will throw an error message that says, “Windows Firewall is preventing connections to your computer.

Recently, a number of users reported an error when they tried to open graphic-intensive apps like video games. According to users, when they tried to open an app, they get the “Display driver failed to start” error instead. Thus, if you encounter the same error, then you’ve come to the right place as this post will guide you on how exactly you can fix it. Here’s the full content of the error message:

“Display driver failed to start; using Microsoft Basic Display Driver instead. Check Windows Update for a newer display driver.”

This kind of error could be due to several factors. It is possible that it could be a result of a corrupted or outdated graphics driver. Aside from that, it could also be due to some issues with the system settings. Worry not though for there are potential fixes that can help you fix the problem. But before you troubleshoot the problem, you need to update your Windows 10 computer first and if it didn’t help fix the problem, then here are the potential fixes that should help resolve the “Display driver failed to start” error.

Option 1 – Try to restart the Graphics driver

Although Windows 10 can recover the graphics driver on its own when it crashes, there are times when it fails to do its job. To restart the graphics driver in your computer, simply tap the Win + Ctrl + Shift + B key combination. After that, the graphics driver will be back in less than a second.

Option 2 – Try running the Hardware and Devices troubleshooter

Running the built-in hardware and devices troubleshooter can also help you in fixing the “Display driver failed to start” error.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Keyboard from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the “Display driver failed to start” error or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 4 – Try setting your system for maximum performance

If the first three options didn’t fix the error, you can try setting your computer for maximum performance since Windows 10 allows you to choose the effects you want to activate your system and you can do this by adjusting the performance ratio. Adjusting the performance ratio can be done via a certain setting in your computer – and this setting should be set to “Maximum Performance” to resolve the error.

• In the Windows Search bar, type in “performance” and from the search results that appear, select the “Adjust the appearance and performance of Windows” option.
• Next, a mini window will appear and from there, click on the radio button that says, “Adjust for best performance”.
• Once done, click on the Apply and OK buttons to save the changes made. This should resolve the problem.

The euphoria around Windows 11 is not dying and reveal that Android apps will work natively inside Windows 11 has raised many emotions and questions. So, Microsoft has announced that Android apps will run natively inside Windows 11 OS and that they will reside alongside your other installed ones as icons, etc. It is no secret that many users have been using emulation software to run Android apps inside Windows so far, so what is the difference?

It is still emulation

Whatever you would like to believe it is still emulation and Android apps are at the end of the day still Android apps running inside emulated environment. This time we will not need third-party emulation software running inside Windows, we will have third-party emulation services running inside Windows. Intel has teamed up with Microsoft in order to integrate Intel bridge algorithms in order to run Android apps, meaning that yea, pretty much we have emulation services running in order to run the application. The problem with this kind of approach is that well emulation software is running and consuming system resources only when we start it, this kind of service is always running and always consuming resources and for someone who really does not care about Android apps at all, this is just a waste of resources.

Android store

The store is another issue here, instead of the Google play store we will have the Amazon app store integrated inside the new Microsoft store. This means that any kind of for example game progress or login information from Google store cannot be transferred into Windows 11, add to that information that in the Amazon app store there are tons of missing applications like SLACK, TRELLO, BitWarden, etc and we might have a serious question here about the use of this feature.

Android apps that do not use Android services

If you even look past that it is still emulation and that it is available on the Amazon app store there is still concern about applications not using Google services for their running. Many Android apps are relying on Google services like location or optimize their use of on-device resources, handle in-app purchases, etc. that cannot be found on this system. Uber is a prime example that uses Google location service to determine your location and for its mapping data, with that application, is useless. Other like Guardian will even pop up message that says Google play service is required in order to even work.

Android apps without Eero system

Amazon Eero system for enhanced internet access is not even yet available in its own app store which brings us to missing some key players like Bank of America, Chase mobile, Bueller, etc. And across the board, the apps that are present in the Amazon Appstore are often as good as abandoned. Lots of titles are numerous versions behind their up-to-date Play Store counterparts, and plenty of programs you encounter in the Amazon environment clearly haven't been touched in years.

Conclusion

Many new Windows 11 features are quality features that I personally consider good but although this one seems innovative and good I simply cannot stand back it up. Android apps were already inside Windows with emulation software which used google services and was working just fine, this was not needed in my opinion.

A recent update in Windows 10 has caused a couple of glitches. One of these glitches is having trouble signing into Windows 10. Some users reported that they were not able to sign in to their computers using a PIN and they weren’t also able to reset it either. If you are one of these users, then you’ve come to the right place as this post will help you resolve issues that you are having in signing in to your computer using your PIN or fingerprint with Windows Hello. When you encounter this issue, you will get an error message on your screen stating:

“Your PIN is no longer available due to a change in the security setting on this device on this device.”

To resolve this problem, you need to follow the steps laid out below carefully.

• Step 1: The first thing you need to do is to make sure that you are using an administrator account. After signing in as admin, tap the Win + E keys to open the File Explorer.
• Step 2: After that, under the View menu, enable Hidden items.
• Step 3: Next, navigate to the following path:

C:\Windows\Service\Profiles\Local\Service\AppData\Local\Microsoft

Note: From there, you should see a folder named “Ngc”. This folder might be the one that’s causing the problem so you are going to fix it by making some changes. This folder contains all the files responsible for any PIN-related settings. So if you are not able to access the Ngc folder, or it has gotten corrupted for some reason during an update here’s how to fix it.

• Step 4: Try opening the Ngc folder. If you are able to open it, just skip to step 11 but if you can’t open it and you got the “Permission Denied” error message, proceed to the next few steps.
• Step 5: Right-click on the Ngc folder and select Properties.
• Step 6: Under Properties, go to the Security tab and click on the Advanced button.
• Step 7: Next, click on the Change link which corresponds to the Owner field.
• Step 8: Then click on Object Types and ensure that everything is selected.
• Step 9: After that, enter your username in the field. You can just use the email that corresponds to your Microsoft account or you can also use the Check Names button to verify it. Now click OK.
• Step 10: You should now see a change in the owner's name. Just make sure that you enable the checkbox below it which is labeled, “Replace owner on subcontainers and objects” and then click Apply and close everything.
• Step 11: Next, try opening the Ngc folder again. You should now be able to access it. After opening the folder, delete all of its contents and make sure that it’s empty.
• Step 12: Restart your PC. After your computer has booted, go to the Account Settings and try setting up a new PIN. You should now be able to set up a new PIN and use it to sign in to your PC.

The Windows Defender program can both scan and monitor almost the entire folder on a Windows 10 computer. So if you have a folder that may have files that could trigger an alarm to Windows Security, then it would be better if you add an exclusion to Windows Security. Note that it is okay to do this as long as you’re certain that the contents of the folder you want to exclude are safe and that Windows Defender is only throwing out warnings for nothing. This way, Windows Defender won’t scan those folders in the future. And besides, there are also some Windows folders and files that you may exclude from the Antivirus scans, especially if you want to save your scan time. This kind of feature also comes in handy when you trust a file type or folder or any process that you believe is safe but the Windows Security considers as malicious. To exclude a folder or a file or process or a file type from the Windows Security scan, here are some steps you can follow. Make sure to do them carefully. Step 1: Search for “Windows Security” in the Search box and then click on it from the search results to open it. Step 2: Next, click on Virus & threat protection > Manage settings > Add or remove exclusions. Step 3: After that, on the next screen, click on Add an exclusion > Folder. It will show you a list that includes File, Folder, File Type, and Process. Step 4: Now click on “+Add and exclusion” on the next window and then select a folder you want to exclude and click OK to add it in the Exclusions list. Step 5: Click on the down arrow button to remove it and then click on the Remove button. Note: If you want to only ignore a few file types, it’s better if you configure your antivirus program to ignore these files with a specific extension. This way, it will ignore all of them no matter what their location is. Also keep in mind that when you select a folder, all the subfolders in it will also be excluded from the scan. Thus, you need to understand what you’re about to do. Once you’re done excluding the folder, it is recommended that you protect the folder using the Controlled Folder Access since this folder is not monitored for threat. The Controlled Folder Access will ensure that an external program does not alter it. This way, you can be sure that even though this folder is not included in the scan, it is still secure.
