A Quick Guide to Fixing Ntdll.dll Error Code

In case you don’t know, Windows now comes with an all-new Light Mode theme which gives a light accent color to the Taskbar, Start, and Notification Area. Aside from that, it also brings new improvements and features. This new theme is somewhere between dark and completely white and in this post, you will be guided on how you can enable this new feature in your Windows 10 computer. Although the Light Mode sure looks stunning and a lot of users love it, it actually switches all the apps plus the Taskbar and Start Menu to the light mode which was not the case before. In addition, the icons in the system tray area, as well as the notification center, are also inverted. To resolve that, there are several ways you can customize the light mode theme as well as activate it in the Windows 10 v1903. How? Refer to each one of the options given below.

Option 1 – Via Theme settings

Windows 10 brought a new theme called “Windows (Light)” which will enable the light mode automatically and will set the accent colors to automatic. This will also apply the new Windows 10 wallpaper on your desktop. To enable Windows (Light), all you have to do is right-click on the desktop and select Themes from the left menu. After that, select the Windows (Light) option under the Change Themes section. This will apply to the Windows (Light) mode.

Option 2 – Via Color settings

The second and more customizable way to activate the light mode is via Settings. Aside from the Light and Dark, Windows also introduced a Custom color option which allows you to decide the default Windows and App mode independently. To enable Light mode via Settings, refer to the steps below.

• First, open Settings and go to Personalization.
• After that, select “Colours” from the left menu.
• Next, select Light under the “Choose your color” section to activate the light mode in Windows 10. This will activate light mode all over your computer.

Note: If after activating light mode, you find that you don’t like it and you want to keep things as they were before (Light App Mode and Dark Windows Mode), you can achieve that using the Custom option. All you have to do is select Custom from the drop-down menu to decide the default Windows and app mode independently. After that, select light under the default app mode and dark under the default Windows mode so that you can keep things as they were before the update. On the other hand, you can also try the opposite version of the light Windows mode and Dark app mode since Windows increased the level of customizability which allows users to use an option of a completely light mode.

System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it. So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not. High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.

Option 1 – Try to update the hardware drivers

As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, update all the outdated Hardware drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions. You can check with the Windows Update History to check out any recent updates as well as the previous ones.

Option 2 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• 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” check box 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 configure Windows to use the usual startup, just simply undo the changes.)

Option 3 – Try to enable or disable Hardware

If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.

• Tap the Win + X + M keys to open the Device Manager.
• Next, navigate to the device you want to disable.
• Then right-click on it and choose to disable the device.

Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.

Option 4 – Try to update the BIOS/UEFI

Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Restart your computer to apply the changes made.

Option 5 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

• 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 Hardware and Devices 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.

Performance Troubleshooter:

• Tap the Win + R keys to open the Run dialog box.
• Type “exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Error 0xA00F4244 or 0x200F4244 is when Windows can not detect the WEB camera in your system and it is usually accompanied by the message: We can’t find or start your camera. There could be several reasons for this error and in this guide, we will cover all of them in order to help you to get back on track and start using your WEB camera which is perhaps now more required than ever in this world we live in.

1. Check privacy settings

   With the latest Microsoft Windows updates come the latest issues and it is not strange that privacy settings can become reset or changed when an update is applied. This is a quick fix to this issue and can be the sole reason why you get this error, go to Windows settings, then to privacy and check to see if the WEB camera is turned OFF, if this is the case turn it back ON and make sure that option Allow apps to access your camera is also set to ON.

2. Check if the camera is enabled

   Sometimes it is by mistake, sometimes by an update but the web camera could be disabled in the device manager of Windows. Right-click on the Windows Start button and click on device manager to open it up, find and expand the cameras category. Right-click on your camera, if it is disabled, you will have the option to enable the camera, if it is enabled and Windows is detecting that it is working fine you will have the option to disable it.

3. Check antivirus settings

   Antivirus and firewall applications are in today's world and life-essential piece of software but they can sometimes create more harm than good, from stopping windows updates to killing important services of applications and preventing internet access being just some examples of their paranoid behavior. Try disabling or turning your protection software OFF and see if your WEB camera will miraculously come back to life. If this is the case, somewhere in the settings of software there is an option that controls this aspect, try to locate it and set it in that way so you are able to use your camera.

4. Reinstall camera driver

   If the previous three solutions failed to produce a satisfactory solution then reinstalling the camera driver might fix the problem. Go to your manufacturer's camera website and download the latest driver for your camera. Go to the device manager and uninstall the driver for the camera, then apply the latest driver and reboot the system.

5. Check connections and cable

   Sometimes an issue is not due to software nature, sometimes it is hardware. Try checking connections and plug the camera in another USB port, twist and turn the cable a little to see is issue cable-related.

6. Check to see if the application supports your camera

   If Windows has detected the camera and is not reporting any issues with it check your application to see if it can detect your camera and that it supports it fully. Sometimes newer applications tend to support only newer camera models. Try to use the camera in other software as well to see if the problem is with the application you are using.

7. Try camera on another computer

   If everything else fails, try the camera on another computer to see if it will work there. If the camera is not working there as well it is probably malfunctioned and broken for good. If it does work there, try to find out what is different in that computer in comparison to yours, maybe it is some service running in the background, certain application configuration, Windows version itself, USB port version, or something else.
