If you are trying to install a Feature Update in Windows 10 but you got the error code 0x80190001, then it means that there is something wrong with the installation files. The installation files are either corrupted or some of them failed to be downloaded. On the other hand, the issue might also have something to do with a driver issue. When you encounter error 0x80190001, you will see the either of following error message on your screen:

“Something went wrong Couldn’t download Windows 10, please check your network settings and try again. You can contact Microsoft support for help with this error. Here’s the error code 0x80190001”. Or: “An unexpected error was encountered while attempting to download files required for the upgrade”.

Here are some fixes that could help you resolve the error 0x80190001. Follow them carefully.

Option 1 – Run the Network Troubleshooter

As mentioned in the error message the issue might have something to do with the network settings of your computer so you can try to run the Network Troubleshooter and then try updating or installing Windows 10 again.

Option 2 – Update Network drivers

• Tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, look for Network Adapters from the list of device drivers displayed. Once you find it, expand it to see the Network drivers.
• Right-click on it and select the option “Uninstall device” – do the same thing for the other Network drivers.
• Restart your PC so Windows can detect and reinstall the drivers you just uninstalled.

Option 3 – Use Storage Sense to clean up temporary and junk files

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
• Windows Upgrade Log Files
• The system created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Note: Once you’re done freeing up space on your drive, try to run the setup file again.

Option 4 – Delete the contents in the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Option 5 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it is also known to help users resolve Windows Update errors like error 0x80190001.

Option 6 – Try to disable your antivirus program

Disabling the antivirus program or any 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 7 – Try to use the 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.

What is Windows Update Error 0xC1900209? Before you can install any updates on your Windows 10 computer, there are a lot of conditions that have to be fulfilled and one of these conditions is software compatibility. It is one of the important factors in installing Windows Updates. So if one of the software in your computer is not compatible with the new Windows Update for your OS, then the Windows 10 setup will not proceed and will block the installation of the new update. This both applies to the cumulative updates and feature updates. In such cases, you will get the following error message when you run Windows Update:

“0xC1900209, Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again.”

This error message comes under the umbrella of the Windows 10 pre-upgrade validation using Setup.exe. And for you to identify the incompatible app, you need to grab a Windows 10 install image using the Windows Media Creation tool to download the suitable Windows 10 version and mount it. After that, execute the setup.exe file that’s located in the root folder of the Windows 10 install image. Once you execute the setup file, the upgrade wizard will give you a list of incompatible apps. Once you have determined which software is not compatible with the Windows Update, there are two options you can try to resolve the Windows Update error 0xC1900209 – you can either try to update the conflicting software or uninstall it. For more details, follow the given options below.

Option 1 – Try to update the conflicting software

If you are using an older version of the software that’s in conflict with the Windows Update, you might want to update it to its latest version and then try to apply the updates again to your Windows 10 computer. You can update the concerned software by visiting the official website of the software or any of its distribution sources. On the other hand, you can also use the Check for updates feature of that particular software if it’s available.

Option 2 – Try to uninstall the conflicting software

If updating the problematic program didn’t work, the next option you can try is to uninstall it. All you have to do is follow these steps to uninstall it successfully:

• Tap the Win + R keys to open the Run dialog box.
• Then type “appwiz.cpl” in the field and tap Enter to open the Programs and Features in Control Panel.
• Next, arrange the list of installed programs in the order of the installation date.
• After that, look for the problematic program and right-click on it, and then select Uninstall.
• Once the uninstallation process is done, restart your computer and see if the Windows Update error 0xC1900209 is fixed or not.

Recently, a number of users reported an error while trying to update their computers. This particular Windows Update error has an error code of 0x80073701. If you are one of the users who encounter this error, then read on as this post will guide you on how exactly you can fix it. Here’s the exact context of the error:

“Updates failed. There were problems installing some updates, but we’ll try again later. 2019-07 Cumulative Update for Windows 10 Version 1903 for x86-based Systems (KB4507453) – Error 0x80073701”

The Windows Update Error 0x80073701 also comes with a code “ERROR_SXS_ASSEMBLY_MISSING” which indicates that some system files are missing on your computer that caused the update installation failure error. Although this Windows Update error does not cause any severe issues, it is still being reported in the section of Windows Update where it is marked as “Update failed”. There are several potential solutions you can check out to resolve this error. You can try to run the DISM tool or the SFC or System File Checker scan. You could also try to run the Windows Update troubleshooter. For more information, make sure to follow the options given below.

Option 1 – Restart your computer and try installing the Updates again

Restarting your computer can also help in fixing the Windows Update failed to install error 0x80073701. There are cases where the issue resolves on its own as it could just be some simple network or PC error.

Option 2 – Try to run the DISM tool

Running the DISM Tool 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”.

• Open the Command Prompt as admin.
• Then type in this command: 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.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening is less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 3 – Try to run the System File Checker

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 causing the error 0x80073701. 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:
