How to Fix the Error Code 28

The store is not downloading Apps: As you know, the Windows Store is one of the places where you can download Windows apps. However, there are times when you might not be able to do so for some reason. For instance, if you search for an app and click on the get it now button, instead of downloading the app, nothing happens and there are also cases when the download will start but the page will refresh after half a second. When this issue happens, you won’t be seeing any error message or warning at all. So you’ll just have to look at the download get started where the page will refresh and you’ll be back at the Get button. This issue in the Windows 10 Store only happens for a few apps so even though you are able to download some apps, you might be able to do on other ones. Note that the apps affected are random and there is no specific set of apps that cause this issue while downloading and that this problem will repeat again each time you click on the Get it now button. This issue is definitely caused by Windows itself and has something to do with a bug in the Windows store which was brought by the latest Windows Update. It’s already a known issue among other Windows 10 users who are also suffering the same dilemma. So until Microsoft releases another update to fix this bug, you will have no choice but to deal with it in the meantime. On the other hand, you can also try a couple of suggestions laid out in this post. Follow the steps in every option given below to fix the issue with the Windows 10 Store.

Option 1 – Try signing out from the Microsoft Store

A lot of Windows 10 users were able to resolve the problem by simply signing out and signing back into the Microsoft Store. How? Follow these steps:

• Go to the Microsoft Store.
• Next, go to the Get page of the app you were trying to download.
• And then click on your account picture located in the top right corner of the window and select your account.
• Sign out from your account and after that, click the Get button to download the app.
• After that, a new window will appear where you’ll have to select your account and click on Continue.
• Now enter your credentials. Once you do, the app should be downloaded automatically after you’re signed in. And that’s about it.

Note: Keep in mind that this option is merely a temporary solution to the problem and once you close the Microsoft Store and open it back again, you will be back to square one.

Option 2 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.

In case you don’t know, a teletype network, also known as Telnet, is a protocol that is meant for internet or LAN communication which is used primarily to control other computers effortlessly. And it is available as a command-line utility in Windows and helps users in opening a command-line interface for the remote computer. However, a lot of users have reported an error that states, “Telnet is not recognized as an internal or external command, operable program, or batch file” when you try to use it. If you are one of these users, then you’ve come to the right place as this post will guide you on how to fix this error in Windows 10. This kind of error means that the Telnet utility is not installed on your computer but Telnet is a default feature in Windows 10 so the protocol mainly is not enabled yet. The Telnet client is disabled by default in Windows 10 and to fix this error, you can try to enable the Telnet Client via Programs and Features or try to install Telnet using an elevated Command Prompt.

Option 1 – Try to enable the Telnet Client via Programs and Features

The first thing you can do is to enable the Telnet client using Programs and Features since it is disabled by default. To do that, follow the steps below.

• Tap the Win + R keys to open the Run dialog box and type “appwiz.cpl” in the field and hit Enter to open the Programs and Features window.
• Next, select the “Turn Windows features on or off” from the options given on the left-hand side.
• After that, look for the Telnet client from the list and check the checkbox next to it and then click on OK to save the changes made.
• Now restart your computer.

Option 2 – Try to install Telnet via an elevated Command Prompt

If enabling the Telnet client using Programs and Features didn’t work, then you can try to do it using Command Prompt instead. To get started, follow the steps given below.

• In the Windows Search bar, type “command prompt” in the field and right-click on Command Prompt from the search results, and select the “Run as administrator” option.
• Next, execute this command to enable the Telnet client: dism /online /Enable-Feature /FeatureName:TelnetClient
• Once the command has been executed, close the Command Prompt and restart your computer.

If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem. When you encounter this kind of problem on your computer, you will get the following error message on your screen:

“Secure Boot Violation The system found unauthorized changes on the firmware, operating system, or UEFI drivers. Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”

This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

A couple of Windows 10 users have reported an error on domain-connected systems when they tried accessing their computer systems remotely. This occurs when the network level authentication or NLA is enabled on the computer. If you are one of these users, you better keep reading as this post will guide you on how you can fix this error. To resolve this issue, there are several workarounds you can try. You can either disable this option directly via properties or you can also modify some registry entries or sub-keys and restart the system. When you encounter this problem, an error message pops up that states:

“The remote computer that you are trying to connect to requires network level authentication (NLA), but your windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box.”

Or you could also see this error message instead:

“The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support.”

Before you proceed in troubleshooting the problem using the options provided below, you need to create a backup for your data or system restore point as well as make a copy of any registry entries you are going to modify.

Option 1 – Disable Network Level Authentication via Properties

The NLA is a useful tool that provides your computer with extra security and helps network administrators in controlling who can log into the system with just a click of a single box. However, there are times when it can become a disadvantage and could prevent you from accessing your system remotely. Thus, you need to disable it using Properties.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” and tap Enter to open System Properties.
• Next, go to the remote tab and uncheck the checkbox for the “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)” option.
• Now click the Apply button to save the changes made and exit System Properties and then try logging into the remote computer again and see if the problem is fixed or not.

Option 2 – Disable NLA via Registry Editor

Note that you can only use this option if the first one didn’t work for you. Take note that this option will require you to restart your PC completely which could mean some downtime if your computer is running a production server. So make sure to save all your work.

• Tap the Win + R keys to open the Run dialog box and then type in “Regedit” in the field and tap Enter to open the Registry Editor.
• From there, click on File > Connect Network Registry and input the details of the remote computer and then try to connect.
• Navigate to the path below after you’re connected:

HKLM >SYSTEM > CurrentControlSet > Control >Terminal Server > WinStations > RDP-Tcp

• After that, change the values given below to “0”
  • SecurityLayer
  • UserAuthentication
• The navigate to PowerShell and execute this command – restart-computer

Option 3 – Disable NLA via PowerShell

PowerShell allows you to tap into the remote computer and once you’ve targeted the machine, you can execute the commands given below to disable NLA.

• Tap the Win + S to open Search and then type in “PowerShell” in the field. Right-click on the related result and select the “Run as administrator” option.
• After opening PowerShell, execute the command below:

$TargetMachine = “Target-Machine-Name” (Get-WmiObject -class “Win32_TSGeneralSetting” -Namespace rootcimv2terminalservices -ComputerName $TargetMachine -Filter “TerminalName=’RDP-tcp'”).SetUserAuthenticationRequired(0) Note: In the command given, the “Target-Machine-Name” is the name of the machine you are targeting.

Option 4 – Use the Group Policy Editor to disable NLA

Another option you can use to disable NLA is via the Group Policy Editor. This is ideal for you if you are blanket disabling. Just take note that the Group Policy Editor is a powerful tool and that if you make some mistakes by changing values you have no clue about, you can render your computer useless so make sure that you create a backup for all the values before you proceed.

• Tap the Win + R keys to open the Run dialog box.
• Then type in “gpedit.msc” and tap Enter to open the Group Policy Editor.
• From there, go to this path – Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security
• After that, search for “Require user authentication for remote connections by using Network Level Authentication” and set it to disabled.
• Now check if the error is fixed or not.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

System File Checker or 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 that might be the reason why the calculator app is not working properly. 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 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

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!!
