Could not connect to the System Event

There are instances when you open a picture or an image in the Windows Photo Viewer and instead of displaying the image, it displays nothing and you’ll see an error message instead that says, “Windows Photo Viewer can’t display this picture because there might not be enough memory available on your computer”. Although this may look like a clear-cut issue of less storage space or low RAM in your computer, that’s not always the case. Security experts noticed that even when your computer has enough resources and disk space, this kind of problem could still occur. So if you experience the same thing, you need to check the Color Profile of your screen. For more information, refer to the detailed instructions provided below but before you proceed, make sure that you close some processes in the Task Manager or restart your computer and see if it helps in fixing the problem. You can also try using the Disk Cleanup tool. To use it, refer to these steps:

• Tap the Win + R keys to open the Run dialog box and then type “cleanmgr” in the field and hit Enter to open the Disk Cleanup window.
• After that, select the drive you want to clean.
• Now click OK to clean the disk and restart your computer.

If the Disk Cleanup tool didn’t help in resolving the issue, refer to the instructions below. Step 1: In the search box, type “color management” and then select the “Change advanced color management settings for display” option from the search results. Or you could simply go to Settings > System > Display, Advanced display settings, and from there, select display and click on the Display adapter properties of Display. Step 2: Next, switch to the Color Management tab and click on the Color Management button. Step 3: Select the monitor where you’re getting the “Windows Photo Viewer can’t display this picture because there might not be enough memory available on your computer” error in the next window. And if you have two displays, make sure that you select the primary display. You also have an option to identify the monitor. Step 4: Once confirmed, select the “Use my settings for this device” checkbox. Step 5: After that, select the Profile listed under the “Profiles associated with this device” option and then click on Remove. Step 6: Next, go to the Advanced tab and make sure that all settings are set to System default which includes a device profile, perceptual images, rendering intent, Relative Colorimetric, and many more. Step 7: Once you’re done, you have to restart your computer and then try to open the same image you were trying to open earlier and then check if you can now open it instead of seeing the error.

When you try to open a website but instead encounter an “Access Denied, You don’t have permission to access on this server” error message along with the ULR which you aren’t able to access with a reference number, then it is most likely caused by some network-related issue in your browser. Note that this error mostly occurs on Firefox browsers. The “Access Denied” error appears when your Mozilla Firefox browser uses a different proxy setting or VPN instead of what’s really set on your Windows 10 PC. Thus, when a website detected that there is something wrong with your browser cookies or your network, it blocks you which is why you can’t open it. To resolve this error, here are some suggestions you can try. And if you got the same error message on a different browser, you can still follow the possible solutions given below.

Option 1 – Try clearing everything about the website

• Open your browser and tap the Ctrl + H keys on your keyboard.
• After that, look for the listing of the website from your browser history and right-click on it.
• Then select the “Forget about this site” option. This will get rid of all the data such as browsing history, cache, cookies, and passwords. Thus, if you have a password saved or other important data of the website, you have to save it first before you tap the Ctrl + H keys.

Option 2 – Try disabling the VPN

As pointed out earlier, if you are using VPN, this could be the reason why you’re getting the “Access Denied” error so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there.

Option 3 – Uninstall the VPN service you are using or use a different provider

If you disabling the VPN service worked in fixing the “Access Denied” error, you might want to uninstall it. As mentioned, website administrator blocks IP ranges if they notice any malicious activities and because of this, your IP address might fall into the banned range even if you didn’t do anything at all. To uninstall the VPN service, follow the steps below.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the VPN service you are using, select it and then click on Uninstall to remove it.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 4 – Try disabling the proxy server for your LAN

If your PC was just attacked by some adware or malware as of late, it is possible that it has changed the network settings in the system and might display spam advertisements. Thus, you have to disable the proxy server for your LAN. To do that, refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Black Screen During Installation - What Is It?

Many are upgrading their OS to Windows 10, however, it’s not always smooth sailing because users have been reportedly experiencing different bugs including Black Screen after a successful update.

One common issue in installing Windows 10 is the appearance of a black screen after installation. This usually occurs when the user restarts the computer. Initially, there will be a black screen only appearing on the monitor. There are also cases where a mouse cursor is present, while some cases have no cursor at all.

Not only that, it seemed that you’ve lost all your desktop icons when experiencing this bug.

Solution

Error Causes

Just like the other bugs experienced by Windows 10 users, booting to a black screen has reasons. Before you even try to look for the solution, you first have to determine the cause of the error, in this case, the error would be black screen when booting.

• Error on external devices such as printer or mouse.
• Having outdated display/video drivers that normally result in black screen when OS is updated.

If error messages are left unsolved, you may encounter other Windows 10 related issues such as error code 0xc0000142. 

Further Information and Manual Repair

Before you even think of upgrading your OS to Windows 10, you need to know that there are specific system requirements and specifications to be able to successfully update your operating system.

• Minimum of 1 gigahertz (GHz) Processor
• Either 1 (GB) (32-bit) or 2 GB (64-bit) Ram
• You need at least 16 GB of free hard disk space
• A Microsoft DirectX 9 graphics device or later with WDDM 1.0 driver graphics card
• 800 x 600 display
• A Microsoft account and Internet access.

There are more system requirements in order to use other certain Windows 10 features, but we’ll focus on solving your black screen problem in this article.

IMPORTANT NOTE: While it’s possible that you’ll be able to find the solution for your black screen during Windows 10 update, contacting the service of a professional technician or using an automated tool is advisable if you’re not confident in performing the methods to be discussed.

Method 1: Windows 10 DVD Boot

This post will guide you in fixing high CPU, Memory, and Disk usage problems caused by NTOSKRNL.exe. NTOSKRNL stands for “NT Operating System Kernel. This file is a kernel image that is responsible for a lot of systems-based processes such as Hardware Virtualization, Process, and Memory. Aside from that, it is also the one that compresses the old pages of memory that reduces the overall amount of memory being used. If you notice that your computer is running slowly and you find that the NTOSKRNL.exe file is hogging your resources such as disk usage, CPU usage as well as memory usage, then read on as this post will guide you in fixing the problem caused by NTOSKRNL.exe. Make use of the options given below to resolve the issues caused by NTOSKRNL.exe. 1] Scan your computer for potential malware There might be a good chance that your computer might be infected with malware. And this malware might be associated with the NTOSKRNL.exe file and hence making it consume a lot of system resources. So, I would really recommend you to make sure that your Antivirus is up to date and then scan your computer with it specifically the C:/Windows/System32 folder because this is the location where the NTOSKRNL.exe file is located.

Option 1 – Put your computer in a Clean Boot State

The first thing you have to do is to put your computer in a Clean Boot State as this can help you in finding any incompatible programs that are causing the problem.

• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Update or rollback 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 – Try to run the DISM tool

If the first two options didn’t work, then running the Deployment Imaging and Servicing Management might. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to stop the Runtime Broker process

The RuntimeBroker.exe or the Runtime Broker process is the one that monitors access to Windows APIs to make sure that the apps do not violate the core security of Windows. This process usually leaves a very small footprint. However, there are times when it consumes more resources than it’s supposed to and does not release memory after the work is done that results in a memory leak. As a result, it affects NTOSKRNL.exe which is why you have to stop the Runtime Broker process. To do so, refer to these steps:

• Tap the Ctrl + Shift + Esc to open the Task Manager.
• After opening Task Manager, go to the Processes tab and look for the Runtime Broker process.
• Once you find it, check if it is using more than 15% of your memory. If it is, then you most likely have an issue with an app installed on your computer.
• Select the Runtime Broker process and right-click on it and then click on the End Task option to end its process.

Option 5 – Try to run the Performance Troubleshooter

• Tap the Win + R keys to open the Run dialog box.
• Type “msdt.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.

Option 6 – Try using the Windows Performance Toolkit

You can also use the Windows Performance Toolkit in finding the root cause of the problem. Just refer to the following steps to use this toolkit.

• Search for “cmd” in the Cortana Search box and click on Command Prompt from the search results to open it.
• Next, type in the command given below or copy and paste it and then hit Enter:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

• After executing the command, wait for at least 60 seconds and then check the logs of the Windows Performance toolkit which is stored in a file named cpuusage.etl in the folder located at C:/Windows/System32. From there, you should see a list of all the causes of the System Resources being hogged.

There are times when the Windows Search doesn’t work and you wouldn’t have a clue as to why it happened since it does not give any error codes. In such cases, you have to check the error logs in the Event Viewer to find out more about the problem. From there, look for an error with the Event ID 3104 in the Windows error logs and if you see an error message that says, “Enumerating user sessions to generate filter pools failed”, read on as this post will guide you in fixing the problem. Apart from the error message, you might also see more information in the details section of the log that says, “(HRESULT: 0x80040210) (0x80040210)”. This kind of error is most likely caused by something that prohibits the search function from initializing. A lot of users assumed that it could be due to Cortana but it’s actually not. While some users also reported that they encounter the issue after they restarted their computers. This error was also reported with the same event ID 3104 on the Windows Server. According to security researchers, this error could be caused by problems in the Registry entry of Windows search. It could also be due to an issue with the SYSTEM account where it hasn’t been added to the DCOM Security. It is also possible that the Windows Search function has not been initialized. To fix this error, you can try to rebuild the Search Index manually or run the Search and Indexing troubleshooter. You can also check the startup type of the Windows Search service or try some registry tweak.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – 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.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.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. Which 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 CMUDA.old.

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