KVM switch and its usage

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

KVM switch

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

Fix The update isn’t applicable in Windows
There are times when you install a Windows update to your Windows 10 computer but you only got an error message saying, “The update isn’t applicable to your computer”. This is unusual as Windows was the one that downloaded them in the first place. To understand the reason behind this error, read on as this post will also give you a couple of suggestions you can try to fix the problem. One of the main reasons why this error occurs is that your computer might not have the required installed updates and many more. Other reasons include:
  1. The update might be replaced. There are instances when a newer Windows version is already available on the computer and that the version you are trying to manually install is an older version which is why the Windows update failed.
  2. The update might already be installed. There are times when the update process is still in progress and the earlier payload might have already been installed.
  3. It could also be that it’s a wrong update for architecture. As you know, updates are designed accordingly based on the architecture of the computer so if the update you are trying to install does not match the architecture of your CPU then it’s no wonder you’re getting an error message.
  4. Your computer might be missing a prerequisite update. There are Windows updates that depend on other updates so if you missed one and you’re installing another one, it could be the reason why you’re getting the error.
To fix the problem, here are some suggestions that might help.

Option 1 – Try verifying the package and the Processor Architecture

As pointed out earlier, updates are made according to the Windows versions. Thus, if one of the updates failed to install, you need to check if it’s applicable or not. The best way to do that is by searching the Windows update name on the official website of Windows. It could be that the Processor Architecture is not compatible with the Windows Update you are trying to install. If you have an X86-based processor, you can’t install x64-based installations of Windows and vice-versa. This usually happens when you’ve downloaded the update manually and then tried installing it.

Option 2 – Try checking if the update is old

The issue might be because you are trying to install an old Windows update which is why it didn’t work. To check, go to Settings > Update and Security > View Update history. From there, you can look for the update.

Option 3 – Try checking if the update is already installed

To verify the update, just go to the Windows Update history once more as you did in option 2, and then see if the update is already installed or not.

Option 4 – Try checking the prerequisites

AS mentioned earlier, there are some updates that depend on other updates before they get installed on your computer. The best way to verify is by checking the Microsoft Knowledge Base (KB). And to verify if the prerequisite updates are installed or not, just run the command below in PowerShell:
get-hotfix KB1111111, KB2222222, KB3333333
Note: In the command given above, you need to replace “KB1111111, KB2222222, KB3333333” with the actual update KB numbers.

Option 5 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.
  • Go to Settings and click on Update and Security.
  • From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
  • After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

How to Fix Windows 10 Error Code 0xC004E003

What is Error Code 0xC004E003?

Error code 0xC004E003 almost always appears when there are damaged files in the Windows operating system. These files could be corrupt for a number of reasons and are usually a serious danger to the life of the computer system. These file errors may be caused by a number of things. Incomplete installation setup, incorrect deletion of hardware or utilities, or an unfinished file erasure. The trigger might also be in the event that the computer system is contaminated with a virus or adware or spyware, or even by the improper shut down of the computer. Any of these scenarios have the possibility to result in the removal or corruption of data of the Windows system data files.

The data system files that are damaged will give linked data and archives that are missing or wrongly linked. These are needed for the proper functioning of the software. This can also happen when or after installing third-party software that might have changed the system files. If it is suspected that a program installation will need to be stopped, it is best to let it run through the setup and then delete it later. While it installs, it is altering program files, and likely rearranging them. Stopping this in the middle can scramble files associated with the program and files vital to the usage of the computer.

Solution

Restoro box imageError Causes

This error will pop up after installing third-party software that has changed the system files. These system files are necessary to finish the activation process. A restore point will be necessary if it is ultimately determined that a system restore is necessary, to bring the computer back to the state it was in previous to the failed installation.

  • Error code “0xC004E003” appears and does not allow the system to continue the install.
  • The computer will not allow any further access or installation of the program.
  • The computer may crash.
  • The third-party program will not have installed completely or successfully.
  • The system will not start up correctly.
  • Personal files are corrupt or missing.

Further Information and Manual Repair

There are several steps that can be taken when the error code 0xC004E003 appears. It is helpful to know that this can occur from trying to install third party software. Going forward, do not attempt to install third-party software that is not trusted, and does not attempt to abruptly stop the third-party software from installing. This may cause the program to corrupt the files or delete important files. Recovering from this error can be easy if there is a recent restore point already backed up in the recovery portion of the system's files.

  • Method One

Run an error scan. The problem should be resolved after rebooting the computer once these steps have been completed.

  1. Download and save an error code fix utility.
  2. Setup the program and then click the Scan button.
  3. Click the Repair Errors button when the diagnostic has been completed successfully.
  4. Reboot the computer.
  • Method Two

Best when utilized by an expert.

  1. Start the system up and sign in as the admin.
  2. Click on Get Started, then select Programs, Accessories, Tools, and then System Restore.
  3. On the next screen, click on Restore my PC to an Earlier Period, and then click Next.
  4. Select the most recent system restore date within the drop-down menu of “select restore point”.
  5. Click Next.
  6. Click Next on the confirmation window.
  7. Reboot the system after the system has finished restoring.
  • Method Three

Another option for restoring. This method can be used by a novice.

  1. Right-click on the Start button, then select Control Panel.
  2. Look for the Control Panel for Recovery.
  3. Select Recovery, then Open System Restore, then Next.
  4. Choose the restore point right before the problematic installation.
  5. Click Next, click Finish.

NOTE: If there are no restore points available, the system recovery may not be turned on. To check this, go to Control Panel, and select Recovery. Configure System Restore, Configure. Then, select Turn on system protection. Having a current restore point for a computer ensures the ease of recovery if any problems with the computer arise.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Fix The group or resource is not in the ...
A couple of Windows 10 users recently reported getting an error that says, “The group or resource is not in the correct state to perform the requested operation” while opening UWP Applications as well as accessing the File Explorer. You can encounter this kind of error mostly on File Explorer, Microsoft Store application, and other UWP applications. This indicates that this error occurs during both the Windows Classic Application and the Universal Windows Platform Applications. There are several ways to fix this error. You can try to run a System File Checker scan, or run the DISM tool or the Program Compatibility troubleshooter or Windows Store Apps troubleshooter or try to reset or reinstall Windows 10 or the affected application that's not working. However, before you do any of these troubleshooting tips, you can try to perform System Restore first as it could undo the changes you’ve made in the system which might have caused the error.
  • 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.
If System Restore wasn’t able to fix the error, then you can refer to each one of the following options.

Option 1 – Try to use the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the “The group or resource is not in the correct state to perform the requested operation”. To repair these corrupted system files, you can run the DISM commands:
  • Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
  • After that, input each one of the commands listed below sequentially to execute them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • Dism /Online /Cleanup-Image /RestoreHealth
  • Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.

Option 2 – Run the System File Checker Scan

Aside from the DISM tool, you can also run a System File Checker scan. It is another 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 that might be the cause why you’re getting the error. 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:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Reboot your computer.

Option 3 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job. In addition, you can try to run the Windows Store apps troubleshooter as it can also help you resolve the problem.

Option 4 – Reset your computer

  • Tap the Win key or click on the Start button located in the Taskbar.
  • Then click on the Power button at the bottom right portion of the screen.
  • Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.
Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen
  • Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

Windows Update service could not be stopped
If you are running the Windows Update service but decided to stop it but you encountered an error message instead that says, “The Windows Update service could not be stopped”, read on as this post will help you fix the problem. This kind of error appears when you use the Command Prompt to stop the Windows Update service, especially if you are using cmd without admin privileges. A lot of users reported that they were not able to disable the automatic Windows Update in Windows 10 using Command Prompt. The command used to stop the Windows Update service is the “net stop wuauserv” command. However, when some users executed this command, they got the error message. So if you are one of these users that can’t stop the Windows Update Service via Command Prompt, you can try to fix that using PID as well as checking the Service dependencies. For more details, follow the given options below.

Option 1 – Try to stop the Windows Update service via PID

In case you don’t know, each running service or process has its own unique ID or PID and you can find it in the Task Manager. You can use it to stop the Windows Update service. How? Refer to these steps:
  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Next, go to the Services tab and look for the service named “wuauserv” and get its PID.
  • After that, type “cmd” in the Windows Start search and right-click on Command Prompt from the search results and then select the “Run as administrator” option.
  • After opening Command Prompt with admin privileges, execute this command: taskkill /f /pid <PID>
Note: You need to replace “<PID>” with the PID of the “wuauserv” service. For instance, the PID is 6676, then this is how the command should be “taskkill /f /pid 6676”.
  • After you execute the command, you will this message on your screen, “SUCCESS: The process with PID 6676 has been terminated” which indicates that you have stopped the Windows Update service successfully.

Option 2 – Try to check the Service dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.
  • 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 following services:
    • Remote Procedure Call (RPC) Service
    • DCOM Server Process Launcher
    • RPC Endpoint Mapper
  • After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
  • If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Fix Google Chrome screen flickering issue
If you are using your Google Chrome browser and suddenly notice a constant flickering after you’ve upgraded your Windows 10 computer, read on as this post will help you sort out the issue. A lot of users have reported this screen flickering issue in Chrome after having upgraded their devices to a recent Windows 10 build. The bizarre thing about this problem is that it only affects the Google Chrome browser and when it occurs, the Chrome browser will start to flash or flicker. According to users who experience the problem in Chrome, it seems to get worse when they try to play videos on YouTube or other streaming sites. To resolve this problem, many users tried to use Chrome in Incognito Mode, cleared the browser cache as well as cookies. They even tried resetting the browser settings and reinstall Chrome but nothing seems to work. Worry not though as there are still other options you can try to fix the problem and they’re easy ones so you’ll have no problem following them. The screen flickering problem in Chrome appears to be related to the Windows background and color settings as well as incompatible display drivers. This is why it is advised that you have both the video card drivers and Chrome browser updated to prevent the same problem from happening again. To get started troubleshooting the screen flickering issue in Chrome, refer to the following options.

Option 1 – Try modifying the background and colors settings

  • Next, select a Solid Color as the new background from the drop-down menu.
  • After that, check if the problem is fixed. This should be fixed especially if the one that’s causing screen flickering is the Windows automatic background switching.
  • Once you’ve selected the Solid color as the background preference, go to the Colors tab under Personalization. This will open a new window and from there, check the box of the “Automatically pick an accent color from my background” option.
  • Now close the Settings app and open Chrome again.

Option 2 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:
  • First, boot your computer into Safe Mode.
  • After that, 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. From there, look for the Display Adapters and click on them.
