Fixing Error code 15 or Error code 16

Having any kind of hardware malfunction is not a pleasant place to be. Even a minor malfunction like a broken key on a keyword can introduce certain bad feelings, frustration, and difficulty in working. So, what are your options when the dreaded key on the keyboard breaks? From my point of view, there are three options that could be accomplished in order to continue working.

1. Replace broken keyboard with the new one

   Yes, the best and most expensive solution, just bite the bullet and buy a new working one.

2. Replace key with another key

   So you broke some key, if you can replace it with another key which you do not use, this option will work only tho if the broken key is not Space bar, enter or similar with specific shape and size.

3. Remap key

   use Windows power tools to remap key function to another working key

There you go, three options to continue working with a broken key on the keyboard.

Updating your Windows 10 computer isn’t always as easy as it should be since there are times when you might encounter some errors along the way. One of these errors is the error code 0x80246017 that comes with the error message “WU_E_DM_UNAUTHORIZED_LOCAL_USER”. According to Microsoft, the cause of this particular Windows Update error is that “The download failed because the local user was denied authorization to download the content”. So if you got this error when you tried updating your computer, read on as this post will provide you some suggestions on how you can fix it. Before you troubleshoot the problem using the options given below, make sure that you are logged in as administrator. If you are already logged in as an administrator, follow each one of the options carefully.

Option 1 – Try to check the status of some Windows Update Services

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Windows Update – Manual (Triggered)
  • Background Intelligent Transfer Service – Manual
• After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 2 – Try to grant Full Control of the System Volume Information directory

• First, tap the Win + X key combination and then select Command Prompt (Admin) from the given menu.
• After opening Command Prompt with admin privileges, type the following command and tap Enter to execute it:

c md.exe /c takeown /f "C:System Volume Information*" /R /D Y && icacls "C:System Volume Information*" /grant:R SYSTEM:F /T /C /L

• Once the command is executed, it will run a batch of tasks and will show each one of their statuses on the command line window and once they’re done, exit Command Prompt.
• Now restart your computer and see if it fixed the problem or not.

Option 3 – Try to disable your antivirus program or Firewall

Disabling the antivirus program or Firewall or any other security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Windows Update error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• After that, wait until the process is finished and do not close the window as the process will probably take a couple of minutes.
• Once it’s done, restart your computer.

Option 5– Run the Windows Update Troubleshooter

If the DISM tool didn’t work in fixing the error, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including the Windows Update error code 0x80246017. 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 6 – Run Microsoft’s online troubleshooter

Running Microsoft’s online troubleshooter might also help you fix the Windows Update error code 0x80246017. This online troubleshooter is known to help in fixing Windows Update errors, it scans your computer for issues that might be causing the problem and then fixes them automatically.

Among other things and innovations, Windows 11 brings to the table is the game mode. The game mode is a system designed to release some resources and optimize your system when Windows 11 detects that you are playing games. It also turns off automatic updates while the game is active. The game mode is active at all times and usually, everything works great but in some instances, it can sadly cause some performance issues. If you are one of these unlucky people where game mode is not working as supposed to do, don’t panic, we have a quick guide for you on how to turn it off.

1. Press ⊞ WINDOWS + I to open settings
2. Inside click on Gaming
3. Select Game mode
4. Click switch beside Game mode to turn it off
5. Close settings

Everything will be automatically saved and applied and you should not have any issues from now on. If for any reason you wish to turn game mode back ON, just follow the same steps and turn the switch to ON.

ChatZum is a Potentially Unwanted Program that installs a Toolbar into your browser. This program allegedly allows users to zoom in on photos without clicking on them, however, upon further research, it was discovered that this function does not work on the latest version of browsers.

From the Author: ChatZum is a Browser add-on (toolbar) that enables its users to hover over images in Major Social network's websites and view a larger version of an image.

While installing this toolbar will track user web browsing sessions and will record website visits, clicks, and sometimes even personal information. This information is later used to display targeted ads to the user. To allow easier user tracking, the program changes the browser home page and default search engine to Nation Search Advanced, which injects additional advertisements and tracks user activity.

Several anti-virus applications have marked this program as Potentially Unwanted, and it is not recommended to keep it on your computer, especially considering the fact it will most likely not work on your browser.

About Potentially Unwanted Applications

If you have ever installed a free application or shareware, chances are high that the computer will get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has got other hidden objectives. These types of programs are generally bundled up with a free application that you download from the internet or may also be bundled inside the custom installers of many download websites. PUPs aren’t always viewed as “pure” malware in the strictest sense. A fundamental difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who knowingly or unknowingly approves the PUP installation on their computer system. But, there is no doubt that PUPs remain bad news for PC users as it could be quite dangerous to your computer in many ways.

The damage PUPs can do

The unwanted programs after installation display numerous annoying pop-up ads, trigger fake alerts, and sometimes even forces a computer owner to pay for the software. PUPs that come as browser add-ons and toolbars are commonly recognizable. These toolbars alter your homepage and your search engine in the installed web browser, track your web activities, modify your search results with redirects and sponsored links, and eventually slow down your browser and diminish your browsing experience. Potentially unwanted programs use aggressive distribution methods to get onto your computer. The worst part of setting up a PUP is the adware, spyware, and keystroke loggers that could lurk inside. Even if the PUPs really aren’t inherently malicious, these applications still do practically nothing good on your PC – they’ll take valuable system resources, slow down your PC, weaken your computer security, making your PC more vulnerable to malware.

How to avoid ‘crapware’

• Read the EULA thoroughly. Look for clauses that state that you have to accept advertising and pop-ups or bundled applications from the company. • Always opt for the custom if you’re offered an option between “Custom” and “Recommended” Installations – never ever click Next, Next, Next thoughtlessly. • Use a good anti-malware application. Try Safebytes Anti-malware which can find PUPs and treat them as malware by flagging them for deletion. • Be alert if you download and install freeware, open-source applications, or shareware. Do not ever install software applications that seem shady or malicious. • Always download applications from the original website. The majority of PUPs find their way onto your laptop or computer is via download portals, so steer clear of it altogether. Remember the fact that even though PUPs could potentially cause damage and hinder the proper functioning of the PC, they can’t enter into your system without your consent, so be alert not to provide them with it.

Solution

Further Information and Manual Repair

Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.

Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.

Method 1:

First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.

If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.

If you are dissatisfied with your internet speed on your computer but do not want to shell out more money for a faster package or simply there is not a faster package, lay down and enjoy this article where we will go through some common practices and tweaks which will result in increasing your internet speed.
