Each time you open an application inside your Windows 11 operating system, it is opened with standard privileges. Now, please note that your account privileges and application privileges are two different things, you might be the administrator of the system but when you open the app, it still opens with standard privilege. Most of the time running applications with typical settings is fine but from time to time we might have some applications that will require running with administrator privilege in order to work properly. In this case, it is very easy to do it, you just right-click and choose run as administrator. Although a very easy solution, it can be quite annoying if running the app is on a daily basis or even more times per day. If this is the case then right-clicking and choosing to run as administrator can be a daunting task, sometimes you can even forget to run it like this in heat of work and some unforeseen consequences might occur. Luckily there is an easy hack so you can open the chosen application each time as an administrator with a simple double click each time.

Setting application to run as administrator always

1. Locate application executable file
2. Right-click on in and choose properties
3. Click on the Compatibility tab
4. Check the box next to Run this Program as an Administrator
5. Click on Apply
6. Click on OK

From now on each time you open an application normally with a double click, it will be opened as administrator privileges.

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

Kernel32.dll Error - What is it?

To understand Kernel32.dll error properly, here’s what you need to know first: in the Windows operating system, the system32 directory plays a vital role. Inside this directory, there is an element called Kernel32.dll. A DLL (dynamic link library) is a library that contains codes and data that are used by more than one program at the same time. The role of the Kernel32.dll file is to handle memory management and I/O (input and output) operations. Malfunctioning of this file results in a Kernel32.dll error message which leads to program or application failure.

Error Causes

Kernel32.dll files can be attributed to several reasons like:

• Missing or damaged Kernel32.dll files
• Registry corruption
• .Dll files misconfiguration if programs are installed or uninstalled.
• Viral infection or malware attack

It is advisable to repair the Kernel32.dll error immediately to avoid inconvenience and serious computer damages like program lockouts, system failure, freeze, and crash.

Further Information and Manual Repair

All causes for the Kernel32.dll error are linked with the registry. The registry is the major database of your system that stores all the activities you perform on your system. It saves both important data and unnecessary files in the RAM (Random Access Memory) including the junk files, temporary internet files, and obsolete files such as files of the deleted/uninstalled programs. These files accumulate a lot of memory space. It leads to disk fragmentation, data overload, missing and damaged DLL files, and eventually registry corruption. Other reasons for registry issues that trigger Kernel32.dll errors on your system could be malicious software like viruses, adware, and malware. These also corrupt the registry and damaged DLL files.

Kernel32.dll Error Solutions

There are two ways to resolve the Kernel32.dll error on your PC, one is to install two separate tools registry cleaner and an antivirus and run them individually to scan your system and repair it. This option is time-consuming and besides if antivirus software is notorious for slowing down systems. So by downloading a separate antivirus you may have to sacrifice your system’s speed.

One of the smoother things that Microsoft did with the Windows 10 operating system is to separate Cortana from Search. This means that Cortana is strictly now a voice assistant and many users have seen it coming since not everyone uses Cortana. In addition, it also paved the way for other virtual assistants like Alexa to get on board with Windows 10. And now in the newly released Windows 10 v1903, Windows has brought the Voice Activation under Privacy. In this post, you will be guided on how to perform the Voice Activation troubleshooting on your Windows 10 computer. To use Voice Activation in Windows 10, follow, in the Start Search, type “voice activation” and click on “Voice activation privacy settings” listed in the search results. And from there, you can choose to allow apps to use Microphone, like listen in the background as well as select which app can access it. Each time enabled voice assistants continue to listen via microphone for the voice keyword, the app will activate itself for the keyword and will react depending on what you ask it. So if you are using a voice assistant and it didn’t respond when you speak the keyword, just go to Settings > Privacy > Voice Activation and follow these steps:

Option 1: Check the App permission to use the voice activation feature.

You have to make sure that the toggle button for the Voice activation feature is turned on globally. It can be found under the “Allow apps to use voice activation” section. You also have to ensure that the microphone is available for apps that use this feature.

Option 2: Voice activation is not working under the lock screen.

If you tend to use the voice assistant even when your computer is locked, Microsoft has a specific setting that you have to turn on. You need to make sure that the toggle button for the “Allow apps to use voice activation when this device is locked” option is turned on. However, keep in mind that the voice assistants are not locked to only recognize your voice as they also answer to anyone who will use the voice keyword.

Option 3: Check the individual permissions of apps.

If the voice assistant is not working, you have to check each one of the apps’ permissions for voice keyword, and the option to work under locked condition works.

Option 4: Run the Microphone troubleshooter.

If you’ve verified that the settings are in place, then you have to run the Microphone troubleshooter by simply going to Settings > Privacy > Microphone. From there, make sure that the toggle button for the following options is turned on:

• Allow apps to access your microphone
• Enable microphone access for the voice assistant

And if it’s a desktop app, you have to enable the toggle on at the end.

We’ve already covered disabling Security Questions If you want to disable Security Questions on your Windows 10 computer then you’ve come to the right place as this post will guide you in doing exactly that. In this post, you will be disabling Security Questions using a PowerShell script. This PowerShell script is called “Update-AllUsersQA”. It is designed to remove or disable the security questions and answers for local users on a Windows 10 computer. It lets administrators take control of the security questions in the environment and at the same time minimizes the risk that comes with them. If a user has a Microsoft account that’s configured to sign in to Windows 10 then he will not probably notice the Password Recovery questions. On the other hand, if he has a chosen local account for installing Windows, he will e prompted to create three security questions that can be used to reset the password and log into the Windows 10 account in case there is any misfortune. However, if you do not have much use for these Security Questions, then you can definitely have them disabled using a simple PowerShell script which you can download from GitHub. For more details on how to disable security questions in a Windows 10 machine, refer to the steps provided below. Step 1: You need to first download the .ps1 file from the GitHub repository. Step 2: Once you’ve downloaded the file, open the PowerShell window with admin privileges. Step 3: After that, navigate to the folder where you had saved the .ps1 file. Then copy the address of the folder location. Step 4: Next, change the directory by using the following command:

cd "folder location address"

Step 5: After that, enter the following script to disable the security questions:

Update-AllUsersQA

Once you’ve completed the steps above, the Security Questions should be disabled and you will be notified with a message stating that the feature has been disabled. On the other hand, if you have a change of heart and you want to enable the Security Questions back, here are some steps you need to take: Step 1: First, open the PowerShell window as admin. Step 2: Next, run the same script with one more parameter such as:

Update-AllUsersQA -answer SecretAnswer

Step 3: And that’s about it. Do not forget to replace the Secret Answer with your preferred one and once you’re done, it will be set as the answer for all the Security Questions. Step 4: Now all that’s left to do is go to the Settings app to change the answer to the questions and you should be good to go.

Booting the Windows computer system includes loading it from the various boot devices such as drivers, network as well as USB drives when the computer is turned on. The instant the startup sequence is done loading the operating system the system hardware will be ready to perform some complex operations – in this process, the Boot Log in Windows 10 is a record that maintains the list of success or failure of many pieces of Windows 10 system during the booting process. In other words, the Boot Log is the one that keeps a record of all that has happened while loading from the computer storage system to the memory during the boot process. It is available for several devices like network, hardware devices, and the operating system which assist in detecting issues during the boot process and other issues with regards to troubleshooting. Through Boot Log, you’ll know which drivers were unloaded and loaded from the start of the system during the boot process. You have the option to either disable or enable this feature on your Windows 10 PC. Named as “ntbtlog.txt”, the log file lists all the successfully loaded processes and the unsuccessful ones during the boot process. It is saved to the drive C:Windowsntbtlog.txt. As mentioned, you can enable or disable this feature in two ways – the first one is by using the System Configuration or MSConfig while the second one is using the Command Prompt. In this post, we’ll show you how you can enable or disable Boot Log in Windows 10 either way.

Option 1 – Enable or Disable Boot Log using System Configuration

Enable Boot Log:

• Tap the Win + R keys to open the Run dialog box.
• Then type in “msconfig” and click OK to open System Configuration.
• After that, go to the boot tab and check the checkbox labeled “Boot Log” under the Boot options so that you can enable the Boot Log feature.
• Then click on OK to save the changes made.
• Next, click on the Restart button in the prompt window to get started with the Boot Log process.
• After restarting your PC, go to C:Windowsntbtlog.txt to open the boot log.

Note: As pointed out earlier, the log file contains a list of all the successfully loaded drivers and also the list of drivers that failed to load during the boot process and every time you restart the system, the boot log file will keep on updating and will eventually increase the list of entries. For you to locate the drivers and make your troubleshooting a lot easier, I advised disabling the boot log after troubleshooting. To disable the boot log using System Configuration, refer to the steps below. Disable Boot Log:

• Tap the Win + R keys to open the Run dialog box.
• Then type in “msconfig” and click OK to open System Configuration.
• After that, go to the boot tab and unmark or uncheck the checkbox labeled “Boot Log” under the Boot options so that you can disable the Boot Log feature.
• Then click on OK to save the changes made.

Option 2 – Enable or Disable Boot Log using Command Prompt

Enable Boot Log:

• Go to the Start Menu and then type in “command prompt” in the search bar.
• After that, right-click on the Command Prompt option and select the “Run as administrator” option.
• After opening Command Prompt, type in “bcdedit” and tap Enter.

Note: You have to find the Identifier of the current operating system first to enable the Boot log. You can find it under the Windows Boot Loader section in the “Description” field and in this case, it’s Windows 10. You can also find the operating system identifier under the Windows Boot Loader section next to the field name identifier.

• To check if the boot log entry is disabled or enabled, go check the “Bootlog” field under the Windows Boot Loader. And if it turns out that the “bootlog” entry is enabled, the entry will be “Yes”. Otherwise, the entry will be “No”.
• Next, type in the following command with the operating system identifier to enable the boot log.

bcdedit /set {identifier} bootlog Yes

Note: In the command given above, make sure that you replace the given system identifier with your computer’s system identifier. For instance: In this example, the identifier was replaced with the actual operating system identifier as current.

bcdedit /set {current} bootlog Yes

• Afterward, restart the system to start the Boot log process.
• After the restart, go to C:Windowsntbtlog.txt to open the boot log.

Note: Every time you restart your computer, the boot log file will keep on updating which will increase the size of the log eventually. So if you want seamless and easier troubleshooting, it is advised to disable the Boot log after you troubleshoot. To disable it using the Command Prompt, here’s what you have to do. Disable Boot Log:

• Go to the Start Menu and then type in “command prompt” in the search bar.
• After that, right-click on the Command Prompt option and select the “Run as administrator” option.
• Once the Command Prompt is opened, type in the following command and then tap Enter to disable the boot log feature.

bcdedit/ set {identifier} bootlog No

Note: In the command given above, you need to replace the given system identifier with your computer’s system identifier. For instance: In this example, the {identifier} was replaced with the actual operating system identifier as {current}.

bcdedit /set {current} bootlog No

• Now close the Command Prompt.

Windows 10 supports various devices to get connected to which makes it quite a flexible operating system. The connection varies on the fact that the device can be connected either with Bluetooth or other wireless and wired connection. However, no matter how great the features are, there a few times when they bring in some bugs too. One of these bugs won’t allow you to either remove or reinstall the Bluetooth mouse and keyboard device from your Windows 10 computer. So if you are currently experiencing this problem, read on as this post will guide you in fixing it. Before you go over the suggestions laid out below, you need to create a System Restore Point first since, in one of the options, you will be making some changes with the registry files as well as some critical Windows settings. Once you have that covered, refer to the following options.

Option 1 – Configure the Bluetooth Services

The first thing you can do is configure Bluetooth Services.

• Tap the Win + R key combination to open the Run dialog box.

Error Code 0x80073afc - What is it?

Error code 0x80073afc deals with an antivirus program first built into Windows 8/8.1 This error occurs when Windows Defender, the built-in anti-virus software in Windows 8/8.1 and higher, does not start automatically and users attempt to manually start the program. During the initialization period of the program start-up, something goes wrong and users get a 0x80073afc Error message. The error message states there was a problem with the initialization of the program. Windows Defender provides protection of your computer and it is advised by the Microsoft Corporation that you ensure it starts up automatically on every start-up.

Solution

Further Information and Manual Repair

Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.

Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.

Method 1:

First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.

If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.
