USB Kill, a USB device is able to fry and damage your computer, mobile phone, router, etc. This device is quite dangerous and can kill electronics the moment it is inserted into an available port. By now people should know that they should not put unknown USB sticks into their devices because of potential virus and malware threats but this raises using unknown sticks to a whole new level.
Kill kits are not really new to the market, they have existed before but lately, technology really progressed and the latest USB sticks are really good, their success rate is around 95% which is pretty high and should not be taken lightly.
The second thing that you really should not play with strange USB sticks is that they dropped in price really hard, although top Kill kits will still go as high as around 300 USD, there are really cheap ones lurking in Ali Express that are just 6 USD!!! that makes them affordable devices for the mass market.
The device is made to take energy and current from the port it is plugged in, multiply it and release its charge back into the device, successfully frying some components immediately. Some more professional Kill sticks can even fry devices even when the device itself is not powered and can be even started remotely.
The point of this article is to make you aware that you should not in any kind of circumstances use and plug-in USB sticks into your devices that you do not know where they come from, especially from the mail!!
This post will show you how to fix the Windows update error 0xca00a000 which you can encounter during the installation of Windows updates. Here’s the full error message of this Windows Update error:
“Updates failedThere were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:2018-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4345421) – Error 0xca00a000”
This kind of Windows Update error pops up when Windows has missed installing one of the cumulative updates needed or when there is some problem with the driver that won’t let the installation of the updates push through. There are also instances when the system files are modified with incorrect permission that may result in the Windows update error 0xca00a000. Thus, you need to fix the trusted installer permission as well as resolve the issue with the driver. To do these things, you need to follow the options laid out below.
Option 1 – Run the Windows Module Installer
The Windows Module Installer is a built-in service in the Windows operating system that could help you resolve the Windows update error 0xca00a000. You need to make sure that this service is Started and that its Startup type is set to Automatic – you can do this via Services Manager or by executing the command given below in an elevated Command Prompt.
Tap the Win + R keys to open the Run dialog box.
Then type “command prompt” in the field and hit Enter to open Command Prompt.
And in the elevated Command Prompt type in the following command and hit Enter:
SC config trustedinstaller start=auto
After executing the command successfully, you should see the “[SC] ChangeServiceConfig SUCCESS” message on the Command Prompt window.
Option 2 – Try manually installing the updates
As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.
Option 3 – Delete the files from the Software Distribution folder
The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.
Open the WinX Menu.
From there, open Command Prompt as admin.
Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauservnet stop bits
After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauservnet start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.
Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.
Option 4 – Install the updates in a Clean Boot State
You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.
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 that, try to install the Windows Updates or upgrade again.
Option 5 – Run the Windows Update Troubleshooter
Running the built-in Windows Update troubleshooter could also help you resolve the Windows update error 0xca00a000. To run it, go to Settings and then select Troubleshoot from the options.

Sndvol32.exe is actually an important part of the Windows operating system.
Responsible for managing the sound-card volume and running programs properly, the problem occurs when error messages appear. The user will be unable to listen to music on the system. Usually, Windows XP users encounter the Sndvol32.exe error.
Solution
Error Causes
Sndvol32.exe error can be caused by any one or several of the reasons listed below.
Accidental deletion of the DLL file from the system
Damage to the DLL file due to spyware or virus infection
Improper removal of software
Unintentional overwriting on the DLL file by a mismatched version
Obsolete hardware drivers
Several obsolete/invalid registry entries
Corrupt registry entries
Regardless of what triggers the Sndvol32.exe error, it is of utmost importance to take immediate measures to fix the problem and to keep it from occurring again.
Further Information and Manual Repair
If you are looking for ways to fix this error manually, the Windows functionality of System Restore will come into play in this particular scenario.
In case the error is caused by a damaged or corrupt file, performing System Restore is an ideal choice as it will allow you to not only get a fresh copy of the operating system, it will be possible for you to remove the error at the same time as well. The procedure for performing System Restore is outlined below as follows.
Click on the Start menu and type ‘System Restore’ in the search box.
When the icon for ‘System Restore’ appears, click on it.
Now type ‘Restore’ in the search box that appears on the start menu.
The window for the System Restore center will now appear.
Now you have two options. You can either opt for “Recommend Restore” which is the case where the system itself will choose a restore point for you or you can select “Choose a different restore point”. Users are advised to choose the latter option as it is more customizable.
Users can now select from a list of restore points that have been created before. If you observe closely, you will realize that one of the restore points is prior to the occurrence of the Sndvol32.exe error.
Click on the restore point. Once you have confirmed your selection, your system will restart and it will roll back to its previously selected restore point.
One recommendation is to perform the system restore in Windows Safe Mode. This is just to ensure that the System Restore is performed smoothly and any potential problems are kept at bay.
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.
Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match.
When you encounter this error, you will see the following error message on your screen:
“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”
Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212.
You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key.
Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.
Option 1 – Try running the Windows 10 Activation Troubleshooter
The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
Go to Settings and then select Activation.
After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.
The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.
Option 2 – Try forcing Windows 10 ISO to use the right version
You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.
Extract the Windows 10 ISO files using an extractor.
Then browse to the folder you created and go to the sources folder.
From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:
[PID]Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Note: “xxxxx” is the KEY to your Windows version.
Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.
Note: Windows will check the key during the installation and will figure out the right version of Windows.
Option 3 – Contact Microsoft Support for assistance
If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.
There are times when you might notice that the Drive letter from the File Explorer is missing, right after you install an update in your Windows 10 computer. So if you are facing this issue right now, then you’ve come to the right place as this post will guide you on what to do to fix it.
In case you don’t know, a drive letter represents a single alphabetic character which is through A-Z typically. This could be assigned to a physical disk partition, floppy disk drive or the removal device/ CD-ROM/ mapping network drive in your PC.
In most cases, the drive letter “C:” is assigned to the first disk partition where the running Windows is installed. Thus, if the assigned letter is missing from either the Disk Management or the Windows File Explorer, it could result in inconveniences or will leave the partition inaccessible. To fix this problem, you can try to show the missing drive letters manually or make sure that the drive has a drive letter assigned in the Disk Management as well as assign the letter using a tweak in the Windows Registry. For more details, refer to the options provided below.
Option 1 – Try to show the missing drive letters manually
Open the Folder Options from the Start Search and go to the View tab,
Next, scroll down on the list of given options until you see the “Show drive letters” option and then check the box that’s marked against this option.
After that, click on the Apply and OK buttons and then go back to the “This PC” window. You should now see the drive letters
Option 2 – Make sure that the drive has a drive letter assigned in Disk Management
As you know, every drive is assigned a drive letter in Disk Management. However, if it goes missing, you can still get it back through Disk Management. To do so, follow the steps below.
Open Disk Management and from there, right-click on the menu of a partition or volume and you should see a function named “Change Drive Letter and Paths”.
Note: This function allows you to add the drive letter, remove the drive letter and change the drive letter. If the last option, namely, “Remove”, is selected and applied, the letter of the drive will be removed and won’t appear in Disk Management. Thus, this could be one of the reasons why a drive letter is missing.
You need to click on “Add” to assign a letter to the selected drive in order to reverse the change. Note that you must assign the drive with the original letter because if not, the programs that rely on the original letter might not work as expected.
If the original letter is already taken by a new drive, you need to change the letter of that new drive to another available letter.
Then allocate the released letter of the targeted drive.
Option 3 – Try assigning the letter using a Registry tweak
The next thing you can do to fix the problem is to assign the letter using a tweak in the Windows Registry but before you do that, make sure that you create a System Restore point first, after that, follow these steps:
Tap the Win + R keys to open Run and type “Regedit” in the field and then tap Enter to open the Registry Editor.
Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMMountedDevices
From there, check if a device is shown as being mounted at the specific drive letter and then right-click on that drive letter.
Select the “Rename” option from the right-click menu to change the letter to any other available letter.
Exit the Registry Editor and restart your computer.
Option 4 – Try to format the destination drive
Formatting the drive can also help you resolve the error. To format it, follow these steps:
To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
Next, right-click on the drive and select Format.
After that, uncheck the “Quick Format” option and then format your drive properly.
Now once the formatting process is finished, unplug the drive and plug it back in afterward.
Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
From there, right-click on the drive volume and select initialize disk.
Next, select the correct partition type and proceed.
In today's modern world many households have internet access, most of the connection nowadays is done via Wi-Fi or wireless but there is a high probability that you have also a few devices connected via cable. There are of course many disadvantages and advantages between cable connection and wireless connection.
The main advantages of a hard cable connection are of course faster speed and stability compared to Wi-Fi. But if we look into the cables themselves there is also a big difference between them. Not all cables are the same and quality as well as speed vary a lot between them. Choosing the right cable is essential in order to make a maximum of your internet and we have some great tips and explanations of what cables do so you can make the right choice and enjoy your full internet potential.
Not all cables are the same
Cheap cables and expensive ones are not the same no matter what everyone tells you. The old proverb you get what you pay is true and more expensive cables will be made from better materials and will have a higher transfer rate.
Quality network cables are separated into different categories with proper markings and when buying one you should always look for these markings on the cables themselves, do not buy cables that do not have markings since they will often provide lower transfer rates or will not be shielded from outside influences resulting in packet drops and instability in a network.
Categories and what they mean are:
Cat-5 with a maximum speed of 100Mbps, typically unshielded.
Cat-5e with a maximum speed of 1Gbps, available in both shielded and unshielded varieties.
Cat-6 with a maximum speed of 10Gbps for runs under 55 meters (around 180ft), available in both shielded and unshielded varieties.
Cat-6a with a maximum speed of 10Gbps, shielded.
Cat-7 uses a proprietary GG45 connector rather than the standard RJ-45 connector seen on other cables for speeds of 10Gbps, shielded.
Cat-8 with a maximum speed of 25Gbps (Cat-8.1) or 40Gbps (Cat-8.2) at a distance of around 30 meters (around 100ft), shielded.
Unless stated, these standards are typically rated at their quoted speeds for a run of around 100 meters (around 330 ft) and use a standard RJ-45 Ethernet connector. Each generation of cable is designed to be compatible with the generations that came before it, so it’s possible (for example) to use a Cat-6a cable with a router that only supports speeds of 1Gbps.
Shielded cables
When purchasing higher quality cable you might not be able to choose if you have shielding or not since some standards like Cat-6a, Cat-7, and Cat-8 are always shielded. But if you do not have the need for these and you are satisfied with Cat-5e for example you can choose.
Shielded cables are a little more expensive but they will provide you with a coating that will eliminate interference from outside waves making cables more reliable. Of course, if the cable will go through a room that does not have many radio waves or some other interferences then buying a shielded cable is a waste of money.
Cable platings
Usually, there are two types of connector platings on connectors, silver, and gold, and people usually think that gold is much better but there are major differences between silver and gold platings and truth to be told there is no better one, both are different and should be considered depending on your need.
Silver plating will provide you with faster speed since its conductivity is larger than gold, but gold is slower on the oxidation front so its life span is longer. On the other hand, if your cables are always connecting and disconnecting gold will be first to be scrubbed off from the surface since the gold coating is much thinner.
Overall if you would only connect cable once and have slower internet than cable capacity gold is the way to go, in another case if you would use the cable as always connecting and switching and your internet plan is the same as cable transfer capacity you might want to go with silver one.
Cable material quality
Network cables are made from copper, your standard conduction material but even here there are differences in quality and therefore the chance of pocket losses over it. More quality less loss and more stable connection and this will depend on the purity of copper that is used in the cable itself. More purity in copper, more stability, simple as that.
Conclusion
So as you can see, there are a lot of different things that will influence your pick of proper network cable but the overall best advice is to get one that will fit well into your needs and setup. pair it up with your router and your internet plan since just simply buying something that you can not use is really a waste of money.

And so if there is any malfunction with any of these files or services, it will result in some errors when running Windows Update. One of these errors is the error code 0x8e5e0147 which has the following error message:
“There was a problem installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help – Error 0x8e5e0147”
To fix this error, there are several methods you can try. You can run the Windows Update troubleshooter or reset the Windows Update components manually or clear the SoftwareDistribution folder and install the update manually. You could also reset the Windows Update Agent to default using a command in PowerShell.
Option 1 – Try to run the Windows Update troubleshooter
The first thing you can do to fix the Windows Update error code 0x8e5e0147 is to run the Windows Update Troubleshooter. 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 2 – Try to reset the Windows Update components
If by any chance that the third option didn’t work, you can also try resetting the Windows Update components as it could also help you resolve the Windows Update error. How? Refer to the following steps:
Open Command Prompt with admin privileges.
After that, type each one of the following commands and hit Enter after you key in one after the other.
net stop wuauserv
net stop cryptsvc
net stop bits
net stop msiserver
Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS and MSI Installer.
After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below and don’t forget to hit Enter after you type one command after the other.
Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
net start wuauserv
net start cryptsvc
net start bits
net start msiserver
Close Command Prompt and reboot your PC.
Option 3 – Try downloading and installing the Windows Updates manually
Windows Update error code 0x8e5e0147 might be due to a Windows Update that has failed. So if it 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.
