Microsoft has cut out Russia from downloading ISO files for Windows 10 and Windows 11 as well as installation tools without any explanation or reason behind this.
If you connect via VPN to a Russian server and try to download either ISO files or installation tools you will be greeted with the error 404 and an explanation of File or Directory not found or There was a problem with your request.
At this time you can still download Windows 11 Media creation tool but once you run it will throw a 0x80072F8F-0x20000 error with text: For some unknown reason, this tool failed to run on your computer.
People in Russia can still download files if they connect via VPN and go to a server located outside Russia.
Microsoft has not published any explanation why is this happening, it might be technical difficulty or it could be on purpose.
Other histories of Microsoft vs Russia
Since the beginning of the Russian military operation in Ukraine Microsoft has been putting restrictions on Russia starting with a suspension of all sales in March, next month in April Microsoft started suspending developer's accounts on GitHub linked to sanctioned companies and the suspension was even if the developer is not working for a given company or left it.
At the beginning of this month, Microsft laid off 400 employees inside Russia as they began scaling back operations in the country but has also stated that they would continue to provide services to all contractors and customers inside Russia so this sudden blocking of downloads is unexpected and it goes against their statement.
We have all experienced Windows errors over time and that can range from simple ones that will do very little to no harm and can be even system breaking making us lose our work or completely making the PC unusable. No one likes them but they happen, and usually, they happen once we least expect them.
No matter how frequent and unpleasant they might be there are ways to keep them at the minimum and even avoid them.
We will discuss steps that you can take in order to do this, simple tips and guides on how to keep your computer in top form and eliminate not just Windows, but any kind of errors altogether.
Keep your hardware clean
Believe it or not, some serious Windows errors like the dreaded blue screen of death can come from hardware issues not from the software at all. It is very important to keep your computer clean and with enough air flow so it can function properly.
Keeping applications on the drive might seem harmless but sadly that is not the case. Some applications have a certain impact on the system itself after all most of them are tweaking registry entries in Windows and sometimes having too many applications means an increased possibility of conflict over certain resources even when they are not running.
Some applications like adobe creative suite, for example, will have certain services always running in the background, and more of these kinds of applications you have, more services, more places for unexpected errors when they collide. Some of them will also install certain dependencies that could be problematic.
The general idea is: if you are not using it, uninstall it and you will be safer and more resilient to errors inside OS.
Do not use pirated or cracked software
Besides moral and law implications that using pirated or cracked software might bring you there are also certain other things that might be problematic. Certain "free" software might come packet with some problematic malware, for example, it is not uncommon for attackers to use some popular software to pack their malicious application with it.
Other things might be wrong and incomplete tweaking with application in order to bypass security and thus bringing some instability due to scripts needed to run in order to achieve this goal.
Keep your drivers updated
Errors can also come from old drivers or bad drivers, device manufacturers are not all-knowing and perfect, and sometimes drivers can wreak havoc on the system. Having updated drivers can minimize any kind of unexpected behaviors inside the operating system making it more stable and reliable.
You can check your driver version in the control panel inside the Windows OS and then compare it to the ones found on the manufacturer's site, if there are newer available it is recommended to download and install them,
Keep software updated
Applications can have bugs, and bugs can lead to certain errors both in the system and when using the app as well. It is in your best interest to get the latest patch or newer version of the software in order to avoid these unpleasant experiences.
Also, certain codecs and extensions that are installed directly in Windows can also have some unpredictable behavior, updating is the best solution to keep them in line.
Keep Windows updated
Same as with drivers and applications, Windows itself is not immune from bugs and some unpredictable issues. Luckily Microsoft is always working on fixes and features of Windows but in order to actually have benefited from that work, you will need to keep Windows updated. Sometimes a bad update can introduce some errors but you can always roll back to the previous and wait for them to fix everything and then download them all.
Check the health of your hardware regularly
Hardware components have their life cycle, more quality ones tend to last longer but eventually, they will reach the end of their lifecycle. There are a lot of testers for various components in your computer that can check different things and provide you with information about the state of your components.
If you are on Windows 11, Microsoft has included a basic health app inside OS, just type PC health check in search and start the app. For some more detailed information and advanced checks, you will have to use a custom application. There are plenty of them specialized for single components like RAM, SSD, etc. A simple google search with providing you with top results and most of them are free for personal use.
Remember, a faulty component or component that is reaching its life cycle can produce many errors inside the operating system.
As you know, the Windows 10 operating system, as well as other Windows versions, comes with the Windows Firewall. In Windows 10, the firewall allows users to install and run a third-party firewall. This kind of firewall works independently to block any suspicious activity on your computer. However, recently, some users reported that they are getting a notification on the Startup saying,
“Windows Firewall and <Third party firewall name> Firewall are both turned off; tap or click to see available options”.
This particular error could be caused by a lot of factors but when you manually check the firewall, you’ll find that there really is nothing wrong with both the Windows Firewall and the third party firewall. So if both the Windows Firewall and third-party firewalls like McAfee, Comodo, and many others are both turned off in Windows 10, then you need to do several things to resolve the problem – you need to check the supporting services that are required and uninstall and then reinstall the third party firewall on your computer. For more instructions, refer to the options provided below.
Option 1 – Try enabling all the supporting services for the firewall
The first thing you can do to resolve the error with the firewall is to check all of its supporting services by following these steps:
Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
Next, look for the Windows Defender Firewall service among the given list of services.
Once you found it, make sure that its Startup Type is set to Automatic and that the status of the service is Running. So if it’s not running, just click on the Start button.
In addition, you also have to make sure that the following services’ status is set as follows:
Xbox Live Networking Service: Manual
Base Filtering Engine: Automatic
Once done, start the firewall again and check if the error is now fixed or not.
Option 2 – Try to uninstall and reinstall the third-party firewall
It is possible that the firewall error might be due to an error with the compatibility of the installation in Windows 10 and the third-party firewall. Thus, the next thing you can do is to uninstall the third-party firewall and then reinstall it again. Once you have uninstalled the third-party firewall, you can download its latest version from its official website and install it again. This should fix the error with the firewall.
There are a lot of online services and a lot of ways to get your public IP address. One of them being typing whats my IP in Google search and you will get immediate results. But there is a way to get the same information inside Windows 10 which could be very useful if for any reason you can not connect to mentioned services. By checking public IP directly inside your windows you can make sure that the issue for not being able to open some websites is not due to your public IP.
In order to use this Windows feature, we will be checking our public IP using Windows PowerShell.
To open Power Shell in Windows first press ⊞ WINDOWS + R to open the run dialog
Inside run dialog type Powershell and press ENTER
In the Powershell type in the following command and press ENTER
If you suddenly encounter an error message that says, “This webpage is not available, Err_Connection_Closed” while browsing the internet or visiting a website and the website fails to load, then it means that there is some problem with your network connection. Similarly, you may also get other error messages like “Err_Network_Changed”, “Err_Connection_Reset” and “Err_Internet_Disconnected” errors in different browsers like Chrome, Firefox, and Edge.
The problem lies in your Windows 10 computer and your internet connection since this is a network issue. So before you troubleshoot the problem using the suggestions given below, you need to refresh your browser first or you could also tap Ctrl + F5 on your keyboard to hard reload the webpage. If you’re still getting the same error message, then proceed to the guide below.
Option 1 – Try removing the Proxy
Removing the Proxy might also help you in fixing the “This webpage is not available, Err_Connection_Closed” error. Here’s how you can do it:
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 using Google Public DNS
If the first option didn’t resolve the issue, you can try to use the Public DNS by Google and see if it can help fix the problem. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.
The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
Next, click on the “Change Adapter Settings” option.
After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.

netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
ipconfig /flushdns – type in this command to flush the DNS cache
Next, restart your PC and check if the problem’s fixed.
Option 4 – Disable both the Antivirus program and Firewall temporarily
There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’re getting the “This webpage is not available, Err_Connection_Closed” error when trying to browse the internet.
Option 5 – Try to check the network cables and then restart your router
The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting this error.
Option 6 –Try a Network Reset
When all else fails, you might have to consider resetting your entire network settings. Simply follow the steps below to do so.
Click on the Start button and then click on the gear-like icon for Settings to open it.
Next, select Network and Internet.
Then scroll down and look for “Network Reset” – click on it and then click on the Reset now button.
If you suddenly encounter the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error then it means that your computer is under a heavy load. And if you look closely, you’ll see that it has a bug check value of 0x00000050. This kind of Blue Screen error also indicates that invalid system memory has been referenced. It could be that the memory address is wrong, or that it is pointing at freed memory.
The PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error occurs when the requested data is not found in the memory. As a result, the system generates a fault which normally indicates that the system is looking for data in the paging file. However, in this case, the missing data is identified as being located within an area of memory that cannot be paged out to the disk.
This Stop error might be caused by a buggy system service, antivirus program, a corrupted NTFS volume, or faulty hardware. So if you’ve recently added hardware, you can try removing it and then check. If the problem still persists, refer to the suggestions given below to fix the problem.
Option 1 – Run Memory Check to test your memory
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
Select the option you prefer and afterward, check if the Blue Screen error is now fixed.
Option 2 – Run a System File Checker scan
You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:
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:
Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them.
Restart your computer after the scan is completed.
Next, click on Properties and then click on the Advanced System Settings.
Go to the Advanced tab and then click on the Settings button under the Performance section.
Afterward, a new mini window will appear and from there, go to the Advanced tab.
Then click the Change button under the Virtual Memory section. Once you do, another mini window will appear.
Now uncheck the “Automatically manage paging file size for all drives” option.
After that, you have to increase the Page File size by doubling the amount of memory allocated by default in the text field. For instance, the paging size given is a minimum of 16MB and so you have to change it to 32MB. And since the recommended value is 1907MB, you can make its maximum size around 4000MB. By doing so, it will allocate more space for paging into individual drivers.
Now click OK, close all the open windows and then restart your PC.
Option 4 – Update the Device Drivers
Updating the Device drivers can also help you fix the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error. To do so, follow the steps below.
Tap the Win + R keys to launch Run.
Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
Restart your PC and then check if the Blue Screen error is now fixed or not.
Option 5 – Perform a System Restore
Performing System Restore might help you in fixing the PAGE_FAULT_IN_NONPAGED_AREA error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.
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 6 – Try disabling your antivirus programs
There are instances when antivirus programs trigger Stop errors like PAGE_FAULT_IN_NONPAGED_AREA. Thus, you can try disabling your antivirus programs like Windows Defender or other third-party programs if you’re using one.
Option 7 – Use the Blue Screen Troubleshooter
The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PAGE_FAULT_IN_NONPAGED_AREA error. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10.
But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system.
This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues.
All of that being said, let's start.
Setting new font
First thing is to open notepad, in the notepad paste the next block of code:
Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]"Segoe UI (TrueType)"="""Segoe UI Bold (TrueType)"="""Segoe UI Bold Italic (TrueType)"="""Segoe UI Italic (TrueType)"="""Segoe UI Light (TrueType)"="""Segoe UI Semibold (TrueType)"="""Segoe UI Symbol (TrueType)"=""[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]"Segoe UI"="NEW_FONT"
Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font.
Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish.
When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.
Restoring default font
If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:
