If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

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.

Recently, a few users reported that they were unable to turn on their computers for some reason and at the same time their computers Computer makes a beeping noise couple of times or continuously whenever they try to turn them on. The sounds the computers are making can be quite annoying and it also signifies that there is something wrong with them. The problem might have something to do with the hardware inside of the computer system rather than Windows 10 itself. As you know, a computer is designed to deliver audible error sounds every time some part of the hardware is not properly working. For instance, if you hear a single beep, this indicates that your GPU is having some issues and if you’re hearing two beeps, it indicates that your RAM is not working properly, whereas three beeps that repeat after a pause when you turn on your computer means that there is something wrong with the system memory. On the other hand, if your computer is beeping continuously, this means that the problem lies with the processor. To fix this issue, here are some suggestions that might help but before you proceed, make sure that you know how to manage your computer’s hardware, if not, better have some expert do it for you.

Option 1 – Try checking the RAM

One of the basic things you can do in this kind of case is to check the RAM. Prepare some screwdrivers and dig into your PC and then look for the RAM slots and ensure that they are attached firmly. There are times when moving around your computer daily can cause certain components in your computer to become loose. Worst case scenario is that the RAM might be broken so really have to replace it.

Option 2 – Try checking the graphics card

After digging into your computer, check the graphics card and give it some good cleaning. As you know, you have to remove certain components like the graphics card regularly and clean them to help increase their lifespan and avoid errors in a startup. And if it turns out that the graphics card is broken, you have to replace it with a new one to fix the problem.

Option 3 – Try checking the processor

The processor is the brain of every computer so if it ends up not working, everything else is useless. Thus, you need to check it to see if it’s firmly attached and see if it needs some cleaning of dust and other debris. After that, try turning on your computer again. If it doesn’t work, then you might have to take your system to a technician to resolve the problem for you.

There are times when you may encounter some glitches on your Google Chrome browser in your Windows 10 computer. One of these glitches is when the connection status of Chrome keeps on saying “Waiting for cache” which is displayed at the bottom-left side of the browser in the Status bar. At the time of writing, it isn’t clear yet what could be causing this problem. Although it is possible that it’s caused by browser cache, some extensions in the browser. On the other hand, it could also be caused by the browser profile or due to some fragmented files or that the SSD is occupied. Whatever the cause is, you can check out each one of the given options below to fix the problem.

Option 1 – Try clearing browser cache

There are times when some data in the browser is conflicting with the loading of the website and triggers some problems like “Waiting for cache”. And so you can try to clear your browser’s data.

Option 5 – Try to clean reinstall Chrome

There are instances when programs leave files behind after you’ve uninstalled them and the same thing can happen to Chrome so before you reinstall Chrome, you have to make sure that you have deleted the User Data folder. To do so, refer to the following steps:

• Hit the Win + R keys to open the Run dialog box.
• Next, type “%LOCALAPPDATA%GoogleChromeUser Data” in the field and hit Enter to open the User Data folder.
• From there, rename the default folder and name it something else, e.g. “Default.old”.
• After that, install Google Chrome again and check if the issue is now fixed.

What is RTX

Nvidia GeForce RTX is a high-end professional visual computing platform created by Nvidia, primarily used for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production. Nvidia RTX enables real-time ray tracing. Historically, ray tracing had been reserved for non-real-time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows, and reflections. RTX runs on Nvidia Volta-, Turing- and Ampere-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.

Advantage in games

With incredible lighting and shadows, reflection, better smoke, and water effects, and more, RTX has managed to place awesome real-time effects on your desktop all that’s to Nvidia technology behind it. Of course, in order to harvest this kind of technology and features game itself needs to support and have RTX in it, you can not turn RTX in just any game, the game itself must have technology build in it. Therefore we are bringing you the list of all RTX games you can find currently on the market so you can enjoy at the moment best graphics a PC can offer

Raptor Lake, a new and upcoming Intel 13th generation CPU will break the 6GHz barrier for the first time ever in normal working mode, overclocked mode in Intel words will go as high as 8GHz. CPU will be 15% faster than Alder lake in single-threaded tasks and a stunning 41% faster in multi-threaded workloads.

The current world record for overclocking is 8.72GHz done with AMD FX-8370 and Intel is aiming at breaking that record with Raptor Lake, of course, this kind of extreme overclocking will require some top-of-the-line nitrogen cooling systems.

Raptor Lake will run on the current LGA 1700 socket, so you will not need to buy another motherboard for CPU and they will also be manufactured on a 10nm process which means that you will need to take care of cooling and power supply if they really go over 6GHz.

Mid-range Intel Core i5-13600K processor will come with 14 cores inside and 20 threads running at a maximum P-core frequency of 5.1GHz, while Core i7-13700K will have 16 cores and 24 threads and run on 5.3GHz max P-core frequency. Best i9-13900K will come packed with 24 cores, 8 of them will be P-cores, and the rest 16 are E-cores, and 32 threads. It will reach 5.4GHz frequency but it was stated it can go to 5.8GHz with Thermal Velocity Boost.

After this statement, we can clearly see that the 6GHz breaker CPU will probably be an i9 special KS variant. In other words, specially tested and picked existing i9 running at higher speeds as was with Alder Lake as well where normal i9-12900K ran at 5.2GHz while i9-12900KS was running at 5.5GHz.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

As you know, one of the most useful web browsers all over the globe is Google Chrome. However, it is not without flaws as you could encounter errors while using it. One of these errors is the ERR_UNSAFE_PORT error. This kind of error is caused by the data being accessed using a port that isn’t recommended. When you encounter this kind of error in Chrome, you will see the following error message on your screen:

“The webpage is not available, The webpage at <Address> might be temporarily down or it may have moved permanently to a new address. Error code: ERR_UNSAFE_PORT”

In this post, you will be guided on how you can fix the ERR_UNSAFE_PORT error in Google Chrome on your Windows 10 computer. You can try to set allowed ports or reset or reinstall Google Chrome. For more details, refer to the given options below.

Option 1 – Try to set allowed ports

• To get started, open Google Chrome.
• After that, go to the Shortcut tab and type the following after the whole address in the field named Target: --explicitly-allowed-ports=xxx
• It should look like this “C:/Documents and Settings/User/Local Settings/Application Data/Google/Chrome/Applicationchrome.exe --explicitly-allowed-ports=6666”.
• Now click on Apply and click OK to save the changes made.

Option 2 – Reset Chrome

Resetting Chrome can also help you fix the error. This means that you will be restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome

Option 3 – Try to clean reinstall Chrome

There are instances when programs leave files behind after you’ve uninstalled them and the same thing can happen to Chrome so before you reinstall Chrome, you have to make sure that you have deleted the User Data folder. To do so, refer to the following steps:

• Hit the Win + R keys to open the Run dialog box.
• Next, type “%USERPROFILE%AppDataLocalGoogleChromeUser Data” in the field and hit Enter to open the User Data folder.
• From there, rename the default folder and name it something else, e.g. “Default.old”.
• After that, install Google Chrome again and check if the issue is now fixed.

As you know, the Videos folder can be found under “This PC” by default on your Windows 10 computer. However, as per the reports of some users, there are a few occasions where it somehow gets replaced by the Documents folder. In other words, the Videos folders are replaced by a duplicated copy of the Documents folder. Out of the two Documents folder, one Document folder will contain all the usual files and subfolders while the second one is empty. Although when you click the Documents icon on your Desktop (if you have a shortcut), it will still take you to the right Documents folder. To fix this particular issue and get the Videos folder back in the File Explorer, here are some potential fixes that should help.

Option 1 – Run System Restore

The first thing you can try to do to resolve the problem is to run System Restore. This can help you go back to the previous state of your computer before the issue with the Videos and Documents folder.

• 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.

Option 2 – Try to restore Defaults

The next thing you can do is to restore Defaults. How? Refer to these steps:

• Open File Explorer and then right-click on any of the two Documents folders.
• After that, select the Properties option from the context menu and switch to the Location tab and click on Find target.
• Next, copy the address and paste it in the field above the “Find target” option, and then click the “Restore Default” button.

Option 3 – Try to change the Registry Path

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders
• After that, edit the path for {35286A68-3C57-41A1-BBB1-0EAE73d76C95} under the “User Shell Folders” key to match the path shown for My Videos: %USERPROFILE%Videos.
• Once you’re done, open the folder under “This PC” that has the Documents icon and tap Shift + right-click in the folder background, and then select the “Open PowerShell window here” option to fix the naming of the Documents folder. The path should read: “C:users<UserName>Documents.
• Next, execute this command: ri desktop.ini –force
• The command you entered will delete the files and folders and so when added for Documents, it will get rid of the empty Documents folder.
• Now all you that’s left to do is to find where the target location is going to be for both folders and check if anyone foes to the user name location.
• Then delete the one which goes to the incorrect location.

The new thing from Mozilla is not a browser, it is a VPN!

Besides Firefox, Mozilla offers now Firefox Relay, an app helping you to mask your email and phone number, and a new Mozilla VPN.

Mozilla has recently announced a new subscription model that will let you use all products together for $6.99 per month. Although this is a little more expensive than the competition that goes around for $5 per month note that with this subscription you are having access to all services, not just VPN.

VPN will not only hide your IP address but will also make sure websites cannot access your real location and it encrypts all of your network activity. Relay will give you protection against spam, serving as a shield for your email and limiting spammers from access to your real email address and phone number. With Mozilla subscription will let you use both services.
