Method Three: Use an Automated Tool

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.

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.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.

Same as in Windows 10, Windows 11 also features a lock screen. IN this lock screen by default, you will see a clock and date above the standard Windows 11 background. Not all users will be happy with this choice but do not worry, you can choose and customize your lock screen to better suit your idea of it.

To personalize the lock screen do:

1. Right-click on Desktop and select Personalize
2. Click on the lock screen
3. Choose one of three options and customize it

   • Personalize Your Lock Screen

     this option will let you set a custom image or slideshow for your lock screen. Choose either one that best suits you. Under selecting picture or pictures for the slide show you can uncheck the option to see tips, tricks, and facts on your lock screen.

   • Lock screen status

     when clicking on this option you can select the application widget that you wish to be shown on the lock screen like weather, mail, calendar, etc. Choose if you would like one by clicking on it.

   • Show the lock screen background picture on the sign-in screen

     as self-explanatory this switch will enable or disable chosen lock screen wallpaper on your login credentials screen.
4. Close settings

All settings will be automatically saved and applied and when you wish to lock the screen easiest way is to press ⊞ WINDOWS + L shortcut on your keyboard.

Default Taskbar inside Windows 11 is pretty good if we are talking about its height. Sitting at 48 pixels it is a pretty decent size considering functionality and size ratio but if you want to make it a little larger or smaller know that you can do that as well in order to customize it for your personal needs. Sadly in order to actually change height size, you will have to do it inside the registry editor, but worry not, we are here with you to guide you all the way, one step at a time. Also, note that you can only change Taskbar from normal size of 48px to either small of 32px or large gapping at 72px. Icons will also be scaled proportionally with the taskbar.

Guide

1. Press ⊞ WINDOWS + R to open the run dialog
2. Inside run dialog type in RegEdit and press ENTER
3. In registry editor locate and find HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
4. Right Click on it to select it and create a new DWORD (32-bit) value
5. Name the value TaskbarSi
6. Inside TaskbarSi double click in order to set the value to 0 if you want a small size Taskbar, 1 is if you want to revert back to medium (standard one), or type in 2 if you want a large Taskbar.
7. Save and close the Registry editor
8. Reboot PC

And there you go, you have successfully changed Taskbar size inside Windows 11. If you want to revert back to standard size just repeat steps and place 1 as a value in point 6.

If you encounter a Windows Update error with an error code 0x80070652 and an error message saying, “ERROR_INSTALL_ALREADY_RUNNING”, then it indicates that there was a previous Windows Update that was not installed successfully. This kind of Windows Update error typically happens when it gets stuck and so to resolve it, here are some suggestions that might help.

Option 1 – Restart your computer and try installing the Updates again

You can restart your computer and then try installing the updates once again. There are instances when a simple restart resolves Windows Update errors. Thus, after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Try running the Windows Update troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing Windows Update error code 0x80070652. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try downloading the Windows Update that failed

If the Windows Update that has failed is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:

• Go to Settings and from there go to Update and Security > View Update History.
• Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
• After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.

Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes.

Option 4 – Try to restart the Background Intelligent Transfer Service

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service and is the one that manages the background download of Windows Update, as well as scans for new updates and so on. And if Windows Update is experiencing some problems, you can try restarting BITS but make sure that you have admin privileges to do so.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the Background Intelligent Transfer Service and double-click on it to open Properties.
• After that, you need to set the Startup type to “Automatic (Delayed Start) and click on Apply.
• Now click the Stop button to stop BITS and then click the Start button to restart the service.
• Click OK to save the changes made and then restart your PC.

Option 5 – Try to update Windows after a couple of minutes or an hour

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it a couple of minutes or an hour or so before trying to run Windows Update again.

One of the preferred ways to upgrade Windows 10 is by creating a bootable USB drive. However, you might change your mind when you encounter an error during the Windows 10 Setup that says, “We can’t find a USB flash drive”. Worry not for this error can be fixed using some suggestions that will be provided in this post. The funning thing about this error in Windows setup is that the computer says it’s not there when it’s clearly there. To fix this problem, you need to check if the USB device is accessible on your computer or you can also try a different USB device. In addition, you could check if there are any issues with both the USB 3.0 and USB 2.0 ports as it could be the reason why you’re getting the error or fix the bad sectors in the USB drive as well as see if the USB drive is set as the primary drive.

Option 1 – Try to check if the USB is accessible on your PC

The first thing you can do to resolve the problem is to check if you can access your USB device from your computer. All you have to do is open File Explorer and check if the USB device is listed there or not.

Option 2 – Try to connect a different USB device

The next thing you can do to fix the error is to try connecting a different USB device, specifically the one that has more significant storage space. You also have to make sure that it’s working on a different PC.

Option 3 – Fix any issues with the USB 3.0 and 2.0 ports

Although the USB 3.0 ports are compatible with the USB 2.0 ports, it does not necessarily mean that there wouldn’t be any problem when you use them which is why it’s best to fix any issues in them or better yet, use a compatible drive.

Option 4 – Try to fix the bad sectors in the USB drive via CHKDSK

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 5 – Try checking if the USB is set as the primary drive

You might also want to check if the USB drive is set as the primary drive because if it is, then it won’t appear on the list. It could also be that the USB drive has a primary disk in it. To undo it, you need to use the DISKPART utility.

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• Next, execute the “diskpart” command to initiate the DISKPART utility.
• After that, type the “list disk” command and tap Enter to display the list of disks on the computer. You have to take note of the drive number or letter of the concerned USB drive.
• Once done, type the “select disk <X>” command where X is the drive letter or number and tap Enter.
• Then execute the “list partition” command to see the list of all the partitions in your computer. It should be listed as 0, 1, or 2. 0 is the primary partition.
• Now type the “select partition 0” command and tap Enter and then type “delete partition” to delete the selected partition.
• You can do the same to the other partitions as well and when you’re done, execute the format command to turn the USB drive into a standard one.

Error Code 7 - What is it?

This is a typical system error that occurs during Windows setup. To be precise, this error may pop on your computer screen during the text mode portion of Windows setup. The setup hangs and stops responding and the error message is displayed in either one of the following formats:

‘The file I386Ntkrnlmp.exe could not be loaded. The error code is 7.’ or ‘The file I386L_intl.nlf could not be loaded. The error code is 7.’

Solution

Error Causes

Error 7 may be triggered due to several reasons but the 2 most common causes for this error code are:

• Incorrect settings of the BIOS
• Faulty RAM modules
• Registry corruption

Further Information and Manual Repair

To resolve this error on your system, here are some easy and effective DIY methods that you can try.

Method 1 - Change Back the BIOS to its Default Settings

If the underlying cause of error code 7 is related to incorrect BIOS settings, then it is recommended to restore default settings to resolve. You can reset your computer’s BIOS (basic input and output system) settings to factory defaults by selecting the restore defaults option within BIOS or by removing CMOS ( Complementary Metal Oxide Semi-Conductor) battery from your unplugged computer for about five minutes. The battery removal method requires opening the computer case, so only attempt it if you are unable to access BIOS. To reset BIOS follow these steps, reboot your PC and then press the key assigned to loading BIOS during your computer boot splash screen.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.
