If you have encountered the “YOU ARE NOT AUTHORIZED TO ACCESS THIS WEB PAGE AS PER THE DOT COMPLIANCE” error while trying to visit a website using either Firefox or Chrome browser, then read on as this post will guide you on how you can fix this error. Apart from this error message, you might also see an alternative message that says, “Web Page Blocked! The page you have requested has been blocked because the URL is banned as per the Government Rules”. When you get any of the aforementioned error messages when visiting a website, this means that it has been marked. It is mostly recommended to not access the site as it might be blocked for some illegal reason. However, if you are certain that the website is legitimate and safe and you believe that it has been blocked by accident, then you can check out the given methods in this post to unblock and access the blocked or restricted website. There isn’t actually a straightforward way to remove the restriction on the website or the DOT compliance. And it won’t matter what browser you use as you will still get the same error. Thus, the best way to go about this issue is for you to bypass the ISP restriction. But before you proceed, keep in mind that the ISPs (Internet Service Providers) can block any website when a request goes through their servers.

Option 1 – Try changing the DNS

If the request to access the website does not go through the ISP’s DNS server, you might have a chance in accessing it by changing your DNS settings. You can try using the Google Public DNS.

• 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.

Option 2 – Try to install a Proxy Extension

You could also try installing a Proxy extension or Proxy software as it could also help you access the website you are trying to open as it allows you to access the blocked websites by routing the request through their server. Aside from that, it can also hide it from ISPs to make them look like the content is coming from the proxy servers.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. There is a lot of free VPN software out there but just make sure that you install a trusted one. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Check the Windows Host file

You can also try to cross check the Windows Hosts file to find out if the website you are trying to open has been blocked because if it is, then it’s no wonder why you’re getting the ERR CONNECTION TIMED OUT error in Chrome. There are instances when some third party application modifies the file and add some websites to the block lists. So if the website is indeed blocked, you need to remove it from the list.

Option 5 – Try to contact your ISP

If none of the options given above worked, then you can try to contact your ISP as there are times when DOT clears a website, the ISPs are still blocking it. Thus, it’s probably better if you reach out to them and ask them to unblock the website from their end.

Each year Steam makes a couple of large sales, and each year there are speculations and leaks on the date when the sale is going to happen and when it is starting. It seemed that Steam has become aware that these leaks will not stop and that store really cannot hide that kind of important date from the public so in the latest news Steam Purley has just given the date of this year's big winter sale. Probably tired of even trying to hide it, Steam has released that this year's big Steam Winter sale is officially starting on December 22nd, 2021, and closing on January 5th, 2022. So if you have someone to buy a gift or just want to drop a few great games in your library at a low price this is the time when you should do it.

If you encounter a Blue Screen error that points to the Wdf01000.sys file, then this post might be of help. Wdf01000.sys is a file related to the Windows Driver Framework which is the one that manages the system drivers. So if this file ends up being corrupted, the drivers would start to cause trouble in the system which would lead to a Blue Screen of Death error eventually. There are lots of error descriptions that are associated with the Wdf01000.sys file such as:

• DRIVER_IRQL_NOT_LESS_OR_EQUAL
• System_Thread_Exception_Not_Handled
• Page_Fault_In_Nonpaged_Area
• System_Service_Exception
• Kmode_Exception_Not_Handled
• DRIVER_VERIFIER_DETECTED_VIOLATION

Although the troubleshooting steps you must take depends on the kind of BSOD error you are getting, there are a couple of options you can try to resolve the Blue Screen errors related to the Wdf01000.sys file. Refer to the options given below.

Error 0x8004210A - What is it?

0x8004210A is a typical POP3 email error message. This error may sometimes occur when you try to check your Post Office Protocol 3 (POP3) email account. 0x8004210A error code hampers your ability to both send and receive e-mails on your Outlook account. Error 0x8004210A is displayed in any one of the following formats on your PC:

The operation timed out waiting for a response from the receiving (POP) server 0x8004210a Task 'SMTP server name - Sending and Receiving reported error' (0x8004210A): 'The operation timed out waiting for a response from the receiving (POP) server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Error Causes

Error 0x8004210A occurs due to several reasons. However, some of the most common reasons include:

• Wrong port number for the POP incoming server
• Your connection to the mail server is too slow
• Incoming and outgoing emails are being scanned and stopped by an antivirus installed on your system
• The Outlook send and receive job is being blocked by Firewall
• You are sending and receiving large series of emails or large email attachments
• Registry issues

No matter what the cause of this error is, to resume email communication via Outlook and to ensure your work productivity is not affected, it is recommended that you resolve this 0x8004210A error code on your PC immediately.

Further Information and Manual Repair

To fix error 0x8004210A, here are some of the most efficient and easy manual methods that you can try:

Simply wait for the large email to be sent or received before you start sending another email.

Method 4

If the antivirus installed on your system is the reason for the error pop up, then disable it for a while until the operation is complete. Then enable it once the task is performed successfully.

Method 5

Similarly, if the Firewall installed on your system is preventing Outlook from reaching your mail server, then simply disable the Firewall to resolve.

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.

Installing Windows updates, installing a new driver from the manufacturer, or even just installing an application or game can cause sometimes certain components of your computer to stop working properly or introduce issues that were not present just before mentioned installation. Luckily for all of us, Microsoft seems aware of this potential issue and we have the option to roll back an older driver which performed well and had no issues at all. In order to do this first press ⊞ WINDOWS + X to open the hidden start menu and click on Device Manager. From the Device Manager choose the troublesome device and right-click on it, choose properties. Device properties floating Window will appear. Click on the top tab which says, Driver. From the Driver tab, click on Roll Back Driver. Note that if the device is working properly, the Roll Back Driver button will be greyed out and you will not be able to click on it meaning that chosen device is not the issue. If the device is not working properly and you can click on Roll Back driver, do it, choose the previous version, and reboot your computer. You can use this method to get back to the previous driver version for any device that is causing issues in your computer.

Building a custom PC is a great feeling but it can sometimes not be ideal and we are not talking about breaking or losing parts. What we mean is that choosing the right components can be sometimes a difficult task. Of course, picking a PC case can have its issues, choosing the right power supply can be tricky but pairing all components together, especially CPU and GPU can be tricky. Builders with no depth knowledge and experience can sometimes choose improper CPU or GPU, picking one of them to be much more powerful than another thus not using it to its full potential because another component cannot handle stuff at the same speed. In order to not be trumped by this kind of stuff, there is a website that is completely free and you do not even need to be registered in order to use it. Bottlenet calculator link here What is even better, once you input your components you will get advice on what to change in order to tweak the system a little more to avoid bottlenecks even more. It is a very useful tool and we are advising you to use it in order to save money but not throwing it on some component that will be half used.
