The system found unauthorized changes

Athwbx.sys or the Qualcomm Atheros driver file is known to trigger several Blue Screen of Death errors. This occurs when the driver gets corrupted or when the operating system is unable to access or find it. In addition, bad sectors in the hard disk or RAM can also cause BSOD errors. The athwbx.sys file is known to cause the following BSOD errors listed below:

• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (athwbx.sys)
• STOP 0x0000000A: IRQL_NOT_LESS_EQUAL (athwbx.sys)
• STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED (athwbx.sys)
• STOP 0×00000050: PAGE_FAULT_IN_NONPAGED_AREA (athwbx.sys)
• Your PC ran into a problem and needs to restart. You can search online later for this error: athwbx.sys

Before you proceed with the troubleshooting tips given below, you might want to try performing System Restore as it could resolve Blue Screen errors caused by the athwbx.sys file. To run System Restore, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that you create a System Restore point first.

Option 1 – Try recreating the athwbx.sys file

The first thing you can try is to recreate the athwbx.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to athwbx.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the athwbx.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

Option 4 – Try to run the CHKDSK utility

Running the CHKDSK utility might also help you resolve the athwbx.sys Blue Screen error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the Memory Diagnostic Tool

Running the Windows Memory Diagnostic tool in Windows 10 might also help you in fixing the athwbx.sys Blue Screen error. Refer to the steps below on how to run this tool:

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like athwbx.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.

As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Why Can’t drag and drop files or folders happens? In case you don’t know, there is a feature in Windows 10 called drag and drop that can help you move or copy files or even folders from one location to another. This feature is useful and can help you move or copy folders and files easier and quicker. However, if you encounter some problem while using this feature, worry not for this post will guide you on what you can do to resolve the problem. There are several suggestions you can check out to fix the problem. You can try to simply tap the Esc key or you could also troubleshoot the problem in a Clean Boot State. Aside from that, changing the drag height and width or disabling the User Account Control via Registry Editor might also help. For more details, refer to the instructions laid out below.

Option 1 – Try to tap the Esc key

According to some users who experienced the same dilemma, by simply tapping the Esc key, they were able to resolve the problem. All they did was tap the Esc key before they drag and drop the folder or files. Thus, you can try doing the same thing as it might also work for you. After you tap the Esc key, you have to check all the background applications and if you see some that could be related to the hotkeys or keyboard, you might have to disable or remove them. Once done, check if the problem is fixed or not.

Option 2 – Try troubleshooting the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the reason why you’re having trouble using the drag and drop feature in Windows 10. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And to configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 3 – Try changing the drag height and width

The next thing you can do to resolve the issue is to try changing drag height and width by following these steps:

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry key: HKEY_CURRENT_USERControl PanelDesktop
• From there, choose to modify both the “DragHeight” and “DragWidth” located on the right pane.
• After that, change the value to a very high number. Note that these values are nothing but pixel size to drag and drop folders or files.

Option 4 – Try disabling the User Account Control or UAC via Registry Editor

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem
• From this path, modify the value of “EnableLUA” from 1 to 0. This should disable the UAC in your Windows 10 computer.

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.

The Adaptive Brightness setting in Windows 10 is a useful setting you can use in adjusting your computer’s brightness.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue. In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state. Step 1: Find out what’s keeping your computer from going to sleep. To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep. To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:

“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”

Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.

Powercfg -requestsoverride Driver "Legacy Kernel Caller" System

Step 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.

powercfg –devicequery wake_armed

After you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings

• Click on the Windows key and type “control panel” in the field and select the related search result.
• Next, select the Security and Maintenance option and click on the Power Options.
• After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
• Now click on the Change advanced power settings button and a new window will appear.
• Then look for the “Sleep” option and expand it. Make sure that the “Allow hybrid sleep” option is on.
• Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.
