Fixing Windows Update Error 80244019

The MP4 MIME-type is a video type that is mainly configured in IIS or Internet Information console. It is the one that instructs a web browser to use the default video application when running MP4 files from websites. MIME which stands for Multipurpose Internet Mail Extensions which offers a way to identify files on the Internet-based on their format and nature. For example, when a content-type header value like MP4 is defined in an HTTP response, the browser can be configured to open the file with the proper plugin. However, there are some servers that don’t have an associated MIME type to support MP4 files and so they fail to play these files. In such cases, you will encounter the “Unsupported video type or invalid file path” error, especially when you use the Internet Explorer browser in Windows 10. To fix this problem, you may have to configure the MP4 MIME type in IIS but you might find that IIS is not enabled in Windows 10 which is why you need to turn it on or enable it first.

A lot of programs in Windows utilize the helper processes to ensure that they can get the job done as early as possible. And one of the programs that use these processes is Microsoft Edge. This built-in browser uses a process called the Edge Content process. The moment you start your computer, these system processes are loaded which makes the Edge browser load faster. To be specific, these are the three processes that are related to Microsoft Edge:

• MicrosoftEdge.exe
• MicrosoftEdgeCP.exe
• MicrosoftEdgeSH.exe

The process that ends with the “CP.exe” is the content process in Edge. However, when this process stopped working, this can affect the Edge browser. In such cases, when you check the Reliability Monitor, you will see that the state of the “Microsoft Edge Content Process” is “Stopped working” which keeps on appearing. To resolve this issue, you can try to clear the browsing data of Microsoft Edge or repair or reset it. You can also try re-registering Edge via Windows PowerShell as well as check your security programs that might be causing interference with the process.

Option 1 – Clear the browsing data of Microsoft Edge

• Open Microsoft Edge.
• Then click on the three horizontal dots to open the menu.
• From there, click on Settings. And under Settings, click the “Choose what to clear” button under the Clear browsing data section.
• Next, check all the checkboxes and then click the Clear button to clear the browsing data in the Edge browser.
• Restart Edge.

Option 2 – Try to reset, repair or reinstall Edge via Settings

You can reset, repair or reinstall the Edge browser through Settings. If none of it helped, you can try the following:

• Open File Explorer and then go to this path – C:/Users/YourUsername/AppData/Local/Packages

Note: Before you type in the path in the Address bar, make sure that you put your user account name in place with the “YourUsername”.

• Tap Enter to proceed.
• Next, look for the folder named “MicrosoftEdge_8wekyb3d8bbwe” then right-click on it.
• Click on Properties and uncheck the option “Read-only” under the General tab in the Properties window.
• Click on Apply and then OK to save the changes made.
• After that, look for the MicrosoftEdge_8wekyb3d8bbwe folder again and delete it. And if a prompt stating “Folder Access Denied” appears on your screen, just click on the Continue button to proceed – doing so will delete most of the content inside the folder except for the folder named “AC”.
• Restart your computer

Option 3 – Re-register Edge via Windows PowerShell

• In the Start Menu, search “Windows PowerShell”.
• Right-click on Windows PowerShell from the search results and select the “Run as administrator” option.
• Type in this command in the PowerShell windows and tap Enter – Cd C:/Users/YourUsername
• After that, type in this command and tap Enter – Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml" -Verbose}
• Restart your PC.

Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml” -Verbose}

Option 4 – Try to check your security program

It is possible that a security program installed in your computer is the one that’s causing the problem which is why you have to check it. According to security experts, there are some security programs that could be detecting the Edge’s content process as suspicious, blocking or terminating it as a result. Thus, you need to modify your security program’s settings to fix the problem.

If the Diagnostic Data level in your Windows 10 computer is configured manually to the non-default security setting of zero and you’ve encountered an error code of 0xc0000005, read on as this post will guide you in fixing the problem with the Remote Access Connection Manager Service.

A lot of users complain about low storage space each time a Windows Feature update is released as well as to complain about not being able to download the updates, slow update experience, and many other complaints. The main issue is that many users do not have enough storage space available on their PCs. And now to make sure that none of the updates gets stuck because of low storage space, Microsoft presented the Reserved Storage feature which comes preinstalled with v1903 or those where v1903 was clean installed. This guide will be showing you how you can enable or disable the Reserved Storage in your Windows 10 computer. As you know, the Windows Update process should have enough space so that it can download, extract and apply the update on the computer. Usually, the size of the Reserved Storage is around 7GB which gives enough space for the update, temporary files, system caches, apps, and many more. And according to Microsoft, the size of the Reserved Storage space will vary from time to time and will depend on how you use your computer.

Explanation

The Reserved Storage space feature is enabled by default on devices that come preinstalled with the May 2019 update or after performing a clean installation of the Windows 10 OS. To check if your computer has this feature, you need to go to Settings > System > Storage and from there click on the “Show more categories” link and then click on the “System & reserved” option. However, if you can’t find the Reserved Storage from the list, then it’s probably because your computer has limited space on the hard disk or it is not a fresh or new install. On the other hand, if you have this feature but have no use for it and want to disable it instead, then read on as this post will also show you how it’s done.

Solution

Keep in mind that when you disable the Reserved Storage feature, chances are, you might be unable to enable it back so you need to make sure that it’s really what you want to do before you disable it permanently. So if you really want to disable Reserved Storage, you can do so using the Registry Editor. Before you proceed, you have to create a System Restore point first and then carry out the following steps.

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionReserveManager
• From there, double click on the DWORD named “ShippedWithReserves” and set its value to “1”.
• Once you’re done, restart your computer and see if the Reserved Storage feature is now gone.

On the other hand, if you want to reduce the Reserved Storage space, there are two ways you can do that. First, you can go to Settings > Apps > Apps & features > Manage optional features and from there, uninstall the optional features that you do not use. The second one is you have to go to Settings > Time & Language > Language and then uninstall the languages and their add-on which you don’t use. Note: The Reserved Storage feature is also used by system processes and apps to create temporary files and once the Reserved Storage space fills up, Windows 10 will delete them automatically. It is undeniable a useful feature so disabling it is not recommended but if you are running on low storage space and don’t have much choice, then you may disable it at your own risk.

If you suddenly encounter a Blue Screen error that points out to either the mfewfpk.sys and epfwwfp.sys files, then this post might help. Both of these files are created by third-party software.

• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Blue Screen 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
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.
