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?

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 Failed to create a graphics device Error

As you know, the Windows 10 operating system has support for a dedicated high-end graphics processor that brings in capabilities inside to support Graphics Cards from NVIDIA or AMD. This helps the operating system to function in a much better way by segregating the graphics-intensive operations from the CPU to a dedicated processor.

Fix DLL is not designed to run on Windows

As you know, DLL files in the Windows environment contain all the code needed by programs in order to properly function. And like with most other software, the functions in the DLL file have to be compatible with Windows especially if they are using any built-in service. So if you encounter an error that says, “DLL is either not designed to run on Windows or it contains an error”, when you try to launch a program, then this could be due to a compatibility issue. To fix this error, read on as this post will walk you through doing that. Based on the reports of users who encountered this error, the error pointed to a DLL file that was either designed to run on a different version of Windows. It is also possible that the DLL file itself is the problem. Here’s the complete error message:

“Bad Image – DLL file is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”

According to security experts, the DLL files that are known to trigger this kind of error message are msvcr100.dll, msvcr110.dll, msvcp140.dll, lmirfsclientnp.dll, and so on. To fix this problem, you can try to update or reinstall the program that’s throwing the error to its latest version. You could also ask the vendor for the latest version of the DLL as well as run a System File Checker scan.

Option 1 – Try to update or reinstall the program to its latest version

The first thing you can do to fix the problem is to update or reinstall the program that’s throwing the error. It is possible that the version of DLL might be using a system call that is deprecated. So if you had updated your Windows 10 computer recently, you might want to check for an update of the software or you could also try to reinstall its latest version.

Option 2 – Try asking the vendor for the latest version of the DLL

The next thing you can do to fix the error is to ask for the latest version of DLL from the vendor. There are times when the software uses an open-source version of DLL so it is better if you ask the vendor if there is a DLL file that has to be updated. If there is, then you need to make sure to register the DLL once you have it.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

Open Command Prompt as admin from the WinX menu.
Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
- exe /[DLL file]
- exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 4 – Try to replace the DLL file from a trusted source

First, you need to get the new DLL file from another computer with preferably the same file version number.
After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
- x86: This PC > C:/Windows/System32
- x64: This PC > C:/Windows/SysWOW64
Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
Now type the “regsvr32 ntdll.dll” command and hit Enter.
Restart your PC and check if the error is now fixed.

Option 5 – Run System File Checker scan

If reinstalling the program didn’t work, you can also try running the System File Checker or SFC scan to fix the error. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

Hit the Win + R keys 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.

Reboot your computer.

Option 6 – Troubleshoot the isDone.dll error in a Clean Boot State

You can also troubleshoot the “DLL is either not designed to run on Windows or it contains an error” in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

Log onto your PC as an administrator.
Type in MSConfig in the Start Search to open the System Configuration utility.

Delete last 15 min of browsing history on phone

As previously announced by Google feature to quickly delete the last 15min of browsing history via one button is rolling out now. For now, only Apple users will be available to use this feature but the Android update is scheduled for later this year, a strange move by Google but it is what it is. For anyone who is unfamiliar with this feature, basically, Google wants a quick way to remove the last 15min of browsing history as a supposedly stated request to make deleting browsing history much easier. Google came up with this idea so you can keep the previous history intact but remove just 15min time frame, no additional explanation was given on why 15 but I presume it is some round number that came up as the middle one with research, read telemetry info. Using quick delete requires being signed into Search with a Google account. Users can access the option by simply tapping on the avatar icon to access the settings then choosing "Delete last 15 minutes."

How to create a public VPN Server on Windows

As you know, a Virtual Private Network or VPN is used to access a particular network from another network which is why it is also referred to as a mini-internet. Moreover, you can use it in two ways. One, you can use it to get you access to a closed server which means that you would not be getting access to the internet. Second, you can also use it to access a set of resources while at the same time get access to the internet. However, what if you want to access your resources at home even when you’re away? And what if you want to use the private server at home or at your office even when you’re away? This is where the callout for a VPN server for yourself comes in. And so in this post, you will be guided in how you can create a public VPN server on your Windows 10 computer. Follow each one of the given steps below to get started. Step 1: Find your IP address. This step is rather simple since all you have to do is open Control Panel > Network and Internet > Network and Sharing Center. From there, click on “Local Area Connection” and then click on Details where you’ll see your IP address next to “Autoconfiguration IPv4 Address”. Step 2: Next, set up port forwarding on your router. In this step, you will have to configure port forwarding in your router so that you would be able to connect to the VPN server through a public network like the internet.

Log in to the Admin Panel of your router. You have to do this since your router will be the gateway for your access to the network.
After you’re logged in, look for the “Port Forwarding” or “Applications and Gaming” or “NAT/QoS” menu tab and other similar names.
Now you need to set the port number to 1723 for connections based on Point to Point Tunneling Protocol.
Then save the configuration and reboot your router.

Step 3: Set up a VPN server on Windows 10.

In the Cortana search box, type “ncpa.cpl” and click on the related entry from the search results.
After that, tap the Alt + F keys to bring down the File Menu and then select New Incoming Connection which will open a mini window where you can allow the user accounts on the particular machine to access the VPN connection.
On the other hand, you can also click the “Add someone” button so that you can add someone else to the whitelist that can access the connection.
Now click on Next and you’ll see an option to select how people will connect to the network. Check the checkbox for the “Through the Internet” option.
After that, you will see a page where you have to configure the network. Just select IPv4 and then click on Properties.
From there, you will be asked to continue some additional settings like letting users access your Local Area Network or how IP addresses will be allocated to these users. Click on OK to save the changes you’ve made.
Click on Allow Access after you configure the network. And if you want to, you have the option to print this information for future reference or for the client machine.
Now click on Close to exit the configuration process.

Step 4: Allow the VPN Connections through the firewall In this step, you will have to allow the VPN connections through the firewall.

In the Cortana search box, type “Allow an app through Windows Firewall” and click on the related search result to open the intended Windows Firewall settings.
Next, click on Change Settings.
Then scroll down to check if Routing and Remote Access is Enabled for both the Public and Private networks and click on OK.

Step 5: Set up a VPN connection on Windows 10 Now all that’s left for you to do is to set up a VPN connection on Windows 10.

Go to Settings > Network and Internet.
From the list of options given, click on VPN located on the left pane to see the related settings.
After that, click on the “+” icon to add a VPN connection.
Next, select Windows Default under VPN Provider and under the Connection Name, input your VPN’s name, and then enter the IP address you got from the VPN service provider under the Server name or address section.
Now select PPTP under VPN type since it is the most commonly used protocol for VPNs.

Fix 0xd00000e5, 0x8007139f, 0x80090030 PIN

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
