Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap.
The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP.
Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted,
"By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform."
Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things.
Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages:
"DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures."
Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface.
Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally."
Technicians on site don't know how to do that and senior network administrators aren't on site.
It seems that it will all be down for a couple of more hours before the issue is resolved.
The win32kfull.sys file is one of the kernel-mode device drivers in your Windows 10 operating system. In case you don’t know, there are two kinds of device drivers – the first ones are the normal drivers that communicate between your hardware and the operating system while the second ones are the kernel-mode drivers. The latter is necessary for booting your OS. And there are times when you encounter the win32kfull.sys error while booting your PC. Here’s the full context of the win32kfull.sys error:
This error could be caused by corrupted or outdated drivers with incomplete files or it could be caused by some driver or software installed on your computer. To fix this error, here are some troubleshooting options you need to check out.
Option 1 – Try updating all the Drivers
As pointed out, the win32kfull.sys error can be due to outdated or corrupted drivers that are not compatible with your hardware. These drivers include but are not limited to display, network, sound, hard drive, and more. If you are not able to access the internet, you can just manually download the update using another PC.
To update your drivers, here’s what you need to do:
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’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
Restart your PC.
Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.
Option 2 – Identify and uninstall problematic programs by putting your PC in a Clean Boot State
One of the main causes of BSOD errors like win32kfull.sys is a problematic program that could clash with your existing operating system as well as computer architecture. There are tons of programs that are either incompatible or conflict with the existing drivers or software in your system. To identify such programs, you need to put your PC in a Clean Boot state. How? Follow these steps:
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” checkbox 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” checkbox.
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.)
After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:
From the “Start” menu, go to System Configuration.
After that, switch to the General tab and click the option for “Normal Startup”.
Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
Then find and click “Enable all” and if prompted, you have to confirm.
Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
Restart your PC when prompted.
Once you have identified the program causing the problem, uninstall it right away from your Control Panel.
Option 3 – Perform an SFC scan
The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the win32kfull.sys error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.
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.
You left your computer to go to the bathroom or to fetch something to eat, maybe you have to answer the phone or open door to a friend and after some time you get back to your computer see the black screen, you move the mouse and it starts to come from sleep slowly.
I am the kind of person who gets annoyed by this kind of behavior, I like my PC to be ON all time when I want it to be ON and my power plan on best performance so naturally, I have turned this sleep feature OFF. If you are interested to see how you to can turn off your screen sleeping follow this easy guide.
Press ⊞ WINDOWS to open the start menu and click on the settings
On settings, screen click on system
When the system dialog opens go to Power & Sleep and on the right side change all values to never.
Please note that after each update Windows tend to reset these settings so you will sadly have to return to this after each major update.
If you got the Microsoft Store error code 0x80072F30 while trying to open Microsoft Store, then it indicates that the Store fails to connect to the internet or is not able to launch successfully for some reason. It could be that the Windows Update Service has stopped or the Windows Store cache might be corrupted or it could just be due to a poor internet connection. Whichever the cause is, you have to fix this error so that you can use Microsoft Store again and you won’t be getting the following error message every time you open the app:
“Check your connection, Microsoft Store needs to be online, It looks like you are not, error code 0x80072f30.”
The error code 0x80072F30 is related to the Windows Store which prevents it from opening properly. To resolve this problem, you can try fixing the problem with the help of the options given below. Follow each one of them carefully.
Option 1 – Check your internet connection
The first and most obvious thing you can do is to check your internet connection. This may only be a basic tip but it sure works like a charm in most cases. And if you have another internet connection available, you can also try connecting to that and see if you can pull up Microsoft Store or not.
1] Change your internet connection:
A basic tip, but sometimes works like a charm. You may want to check if your internet connection has an issue, or you can also try opening a website and see if you can open it and if possible try connecting to a different internet connection and see if the Microsoft Store opens for you. We also suggest you try changing your DNS and see if it helps.
Option 2 – Check the date and time as well as the time zone of your PC
A lot of services and apps rely on the Date, Time, and Time Zone of your PC which is why if they are not configured correctly, a request from the client machine will be rejected from the server and the same thing happens with the Microsoft Store.
First, go to Settings > Time and Language.
From there, check if it is set to Automatic or not – if it is, switch the toggle button off to set the Time and Time zone manually.
Then select the right time zone manually.
On the other hand, if the Time and Time zone is set manually, you have to switch the toggle button on to set Time and Time zone automatically.
Restart your PC and afterward try opening Microsoft Store again and check if the problem’s fixed or not.
Option 3 – Run the Network Adapter Troubleshooter
Since Windows 10 is packed with various troubleshooters – one of which is the Network Adapter Troubleshooter – you can use it to troubleshoot the problem. To use it, follow these steps:
Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
Next, scroll down and select the “Network Adapter” option from the right pane.
Then click on the Run Troubleshooter” button.
After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
Option 4 – Try to reset the Microsoft Store cache
Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.
Right-click on the start button and click on Command Prompt (administrator).
Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
Now restart your PC and afterward, try opening Microsoft Store again.
Option 5 – Check the Windows Update Service status
You might also want to check the status of the Windows Update Service since the proper functioning of this app depends on the Windows Update Service. It could be that there is some issue with the service which is why you’re getting the error code 0x80072F30 while trying to open Microsoft Store.
Tap the Win + R keys to open the Run dialog box.
Then type “services.msc” in the field and hit Enter to open Services.
Next, look for Windows Update Service from the list of available services in Windows.
Once you see it, check if its status is STOP or Pause and then change the status to Automatic.
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.
The 0xc000001d error is a common yet critical error that can occur when Windows is damaged or fails to work as a result of either missing system files or corrupt system components.
This error can be extremely dangerous to Windows as it can inflict major damage to data and component files.
Error Causes
A 0xc000001d error code can occur because of a number of reasons, of which corrupt registry files are the most common, and about 94% of the time, this results in the error. However, virus infection or an adware or spyware invasion can also result in this error.
Outdated drivers and missing DLL files can also be critical and will lead to this error causing major damage to computer files. Contrary to popular belief, incomplete installation and unfinished uninstalls can also because of this error.
Other causes include improper shutting down of computers and improper hardware or software deletion.
Solution
Further Information and Manual Repair
Because of this 0xc000001d error code, Windows can fail in starting some processes and the system’s performance can significantly slow down. In some cases, Windows has problems starting up and the system can freeze.
Lastly, this error code can even result in the Blue screen of death error message, just like other critical Windows errors. If any of the above problems and symptoms occur in your PC, then you should immediately seek to resolve this problem.
In order to resolve this 0xc000001d error code or repair the corrupted and damaged Windows files, you will need a 0xc000001d repair tool. There is more than one method of treating this kind of error code, and here is how you can manually do it:

The quickest and easiest way to log into your computer is when you use the PIN feature in Windows 10. Even though it is a bit slower compared to biometric logins such as Fingerprint and Iris scanning that comes under Windows Hello, the PIN feature is definitely less complicated. However, just like any other module of the software, it is also prone to some errors. In this post, you will be guided in fixing several PIN errors such as 0xd00000e5, 0x8007139f, and 0x8009003. These errors could be caused at different points in time like when you change or create a PIN or when you log into your computer.
To fix the 0xd00000e5, 0x8007139f and 0x8009003 PIN errors, there are various solutions you can try. You may empty the contents of the NGC folder or remove and change the PIN or the password. You could also use the Group Policy Editor or reset the ACLs in the NGC folder as well as run built-in tools like System File Checker and the DISM tool.
Option 1 – Take ownership of the NGC folder and delete its contents
Boot your computer first into Safe Mode.
Next, you need to take ownership of the Ngc folder first and you can do that using Command Prompt.
Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
Next, type and enter this command: TAKEOWN /F C:WindowsServiceProfilesLocalServiceAppDataLocalMicrosoftNgc
Note that the <path> is the location of the folder or file in File Explorer.
Now type and enter this second command: ICACLS C:WindowsServiceProfilesLocalServiceAppDataLocalMicrosoftNgc /grant administrators:F
Finally, once the command has been executed, restart your computer.
Once your computer has restarted, delete all the contents in the Ngc folder and check if the error is now fixed.
Option 2 – Try to remove and change the PIN or password
The 0xd00000e5, 0x8007139f, and 0x8009003 PIN errors could be caused by some conflicting issues with the PIN or password you have set for the User Account of your computer. Thus, you have to remove or change the PIN or password to fix these PIN errors.
Remove the PIN by going to Settings > Accounts > Sign-in options.
From there, go to the PIN section and click on the Remove button.
You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
Restart your computer and then set up a new PIN.
Once you’re done, restart your computer and check if the error is gone now.
Option 3 – Try to use the Group Policy Editor
Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
Next, navigate to this policy setting: Computer Configuration > Administrative Templates > System > Logon
After that, double click on the “Turn on convenience PIN Sign-in” option located on the right-side panel.
Then set its radio button to Enabled. You will see the following description when you do so:
“This policy setting allows you to control whether a domain user can sign in using a convenience PIN. If you enable this policy setting, a domain user can set up and sign in with a convenience PIN. If you disable or don’t configure this policy setting, a domain user can’t set up and use a convenience PIN. Note: The user’s domain password will be cached in the system vault when using this feature. To configure Windows Hello for Business, use the Administrative Template policies under Windows Hello for Business.”
After setting the radio button to Enabled, it will turn on the Logins in your computer using the PIN.
Close the Group Policy Editor and restart your computer for the changes to take effect.
Option 4 – Try to reset the ACLs in the Ngc folder
Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
After opening Command Prompt with admin privileges, execute this command: C:/Windows/Service/Profiles/Local/Service/AppData/Local/MicrosoftNgc /T /Q /C /RESET
The command you entered will start checking for errors and fix them automatically.
Option 5 – Run the System File Checker scan and the DISM tool
System File Checker:
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.
Now restart your computer.
DISM tool:
Open Command Prompt.
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
Dism /Online /Cleanup-image /Restorehealth
After that, wait until the process is finished and do not close the window as the process will probably take a couple of minutes.
Error 1310 is a fairly common type of error encountered by Windows users.
Error 1310 usually generates while a user is attempting to install Adobe Photoshop or some Adobe product on Windows. The message displayed to the user usually states: ‘Error 1310. Error writing to file. Verify you have access to that directory’. Once the error message appears, the installation process will be terminated.
Solution
Error Causes
While there are different conditions that may trigger this error, most likely, they are generated because of the lack of privileges a user has on a Windows log-on.
When this happens, the operating system doesn’t allow the user to access the installation files. Another reason Error 1310 may occur is that often users attempt to log on to the system and choose the ‘Only for me’ option rather than the recommended ‘Anyone who uses this computer’.
Because of this reason, the data is locked for all the other users.
Since Error 1310 can easily disrupt your workflow on the system and may also lead to annoying consequences, it is best advised to treat it as quickly as possible.
Further Information and Manual Repair
There are different solutions to resolve these errors that are briefly listed below as follows.
First and foremost, restart the installation by logging onto your computer from the administrator account. This error will most likely disappear because there is often a lack of privileges that will trigger it. When you will log on from the admin account, you will have access privileges and such errors will be rectified.
Fix any corrupt system files that exist on your system. If the file resides in the Windows directory, this error will be generated. Check if any of your system files are corrupt or damaged. If yes, make sure you repair and return them back to their original position.
This error is sometimes caused because of incorrect registry entries. If the setup program shows errors, it is possible that it is because the system is having problems retrieving data stored in the system registry.
Another way, this error can be avoided is to run the setup in compatibility mode. Compatibility issues are a common occurrence. However, when an installation is performed in the compatibility mode, one can easily steer clear of such errors.
Implement any of the solutions listed above and protect your system against Error 1310.
The Error Code 0x800488AB will appear when a user is in the Windows 10 Mail app and has provided an Outlook.com e-mail address. The mail app will give a message that the “account information is out of date” and it does provide an option to fix the issue. After clicking the Fix button, this error code will show up to the user.
Common symptoms include:
A dialog box will appear with the Error Code 0x800488AB
Microsoft Windows 10 Mail App will not retrieve (or subsequently send) mail
User cannot delete and re-add the Outlook email account in the Windows 10 Mail app
User can still access and log in to various Microsoft websites, including logging into the Outlook Mail website
Solution
Error Causes
This error can be caused by a few different actions of the user when they have changed a password or a PIN number to access their Outlook mail. This error does have a relatively easy fix after the cause is determined and where the break-in information has occurred. A few of the causes may be:
If the user changes their password on the Microsoft website and uses the alternative PIN login method to access the Mail App.
The log-in information on the Microsoft website does not match the login information on the Windows 10 App.
The login information was changed on the Microsoft website and was not updated to reflect on the Windows 10 Mail app.
The Microsoft website and Microsoft Mail app do not share the knowledge of the change in login credentials, therefore the log-in credentials appear to be incorrect when trying to access the Microsoft Mail app. It should be noted that a user may bypass the password option if they log in to the Microsoft Mail app while using the alternative PIN log-in method, thus still leaving the password undetected.
Further Information and Manual Repair
As is the case with all new technology and having a few wrinkles, the release of Microsoft Windows 10 is not left out. There have been a few discussions of errors and bugs, including Error Code 0x800488AB. As of right now, there are three different methods that can be utilized by any at-home user. These methods are rather simple and make sense when the problem has been identified.
Method 1:
Run the built-in Windows Store Apps troubleshooter:
Press the Windows Key and then type ‘troubleshoot’ and hit Enter
Select “View all” on the left panel and run the “Windows Store Apps” troubleshooter from the list displayed and see if it works.
Method 2:
Use the System File Checker tool to repair corrupted or missing system files:
Click Start.
Type cmd, and then press CTRL+SHIFT+ENTER to open the elevated command prompt (I.e. Command prompt with administrative rights).
The User Account Control window should appear, be sure that the action it exhibits is correct, and then press the Continue button.
Type or copy-paste the below command line into it without quotes:
“Sfc /scannow”
Method 3:
Press the Windows Key
Search for "Credentials Manager"
Click on Windows Credentials
Look for any reference to your windows account (generally your @outlook.com is listed)
Delete them.
Then select your account at the top of the start menu and select Log Out.
If using a Pin Code, switch to type input and put your password into the box.
When you go to Mail, and select "Fix Issues" it will detect your password and your account should sync with new emails. In some cases, depending on why this particular error code was caused, you may have to use a powerful automated tool to have it resolved.
The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP.
