What Causes Error Code 0x800F081F?
Error code 0x800F081F is one of four possible error codes, all of which represent the same potential problem. The other three are error code 0x800F0906, error code 0x800F0907, and error code 0x800F0922.
Microsoft .NET Framework 3.5 incompatibility causes each of these error codes. Typically, this happens when you use the installation wizard, the Image Servicing and Management (DISM) deployment tool, or Windows PowerShell commands to enable the .NET Framework.
You will only see the code under Windows 10, Windows Server 2016, Windows Server Version 1709, Windows 8.1, Windows Server 2012 R2, Windows 8 and Windows Server 2012. On these operating systems, Microsoft .NET Framework 3.5 is “feature on demand” (that is, it is not activated by default).
If this feature is enabled, Windows Update will try to obtain .NET binaries and other required files. If your computer is configured incorrectly, a code may appear.
- 0x800F081F: Windows could not find the .NET source files for the installation to proceed.
- 0x800F0906: Windows either could not download the .NET source files, could not connect to the internet, or could not install a role, role service, or feature.
- 0x800F0907: Either the DISM tool failed, or your network policy settings prevented Windows from connecting to the web.
- 0x800F0922: The processing of .NET advanced installers or generic commands failed.
How to Fix Error Codes 0x800F081F, 0x800F0906, 0x800F0907, or 0x800F0922 on Windows 10
Thankfully, the methodology for fixing the first three error codes is the same. There are two approaches you can try. For error code 0x800F0922, you need to jump straight to method two.
1. Configure Your Group Policy
Your group policy settings may affect the ability of Windows to activate the installation.
Note: The Group Policy Editor is only available natively in Windows 10 Professional, Enterprise and Education editions. Fortunately, there is a solution. Follow our guide to learn how to access the Group Policy Editor on Windows 10 Home.
To start, press the Windows key + R to bring up the run dialog box. Next, type gpedit.msc and press Enter. This command will open the window of the Group Policy Editor.
Once the editor appears on your screen, navigate to the left area Computer Configuration > Administrative Templates > System.
Focus your attention on the area on the right. Scroll down until you find the “Specify settings for optional component installation and component repair” entry. You can find it under the folder you see in the top list.
Double link on the entry to open the settings window. Finally, in the upper left corner, check the box next to “Enabled” and click “OK”.

2. Enable the .NET Framework Using a DISM Command
Note: This is the only way to resolve the error code 0x800F0922.
The second method requires you to use the DISM command to activate the .NET Framework. Don’t worry; it’s not as complicated as it sounds. Follow our guide and you will be fine.
Before starting the main process, the first thing you need to do is to make sure you have a Windows 10 ISO image on hand. The ISO version must exactly match your current operating system.
You can use Microsoft’s official media creation tool to create an ISO image. You can download it from Microsoft’s website.
After the download is complete, run the tool and click Create installation media for another PC. On the next screen, select your language and system architecture, and then select the ISO file to start the build process. Burn the ISO file to DVD before proceeding.
Are you ready? Now we can start fixing the error code.
At the beginning, you must install the newly created ISO image. Open File Explorer and double-click the file. It should mount automatically. Alternatively, you can right-click the file and select the “Load” option from the context menu.
If the process is successful, you will see the ISO in the virtual drive in the left pane. Write down the drive letter.
Note: To undo the image, right-click the virtual drive in this PC and select eject.
Once the image is mounted, input cmd in the Start menu search bar. When you see the list of results, right-click Command Prompt and select Run as administrator.
On the command line, type dism /online /enable-feature /featurename:NetFx3 /All /Source:[Drive]:\sources\sxs /LimitAccess. Replace [Drive] with the drive letter you made a note of previously, and make sure you leave spaces in the correct places. When you’re ready, press Enter.
3. Try to Reinstall Microsoft .NET Framework 3.5
After you’ve successfully navigated the instructions, it’s time to install .NET Framework 3.5 and see if error code 0x800F081F (or one of its associated error codes) returns.
Open the Settings app and go to Apps > Apps and Features. Scroll down to Related Settings and click on Programs and Features. Next, in the new window, click on Turn Windows features on or off in the upper left-hand corner.
Finally, mark the checkbox next to .NET Framework 3.5 (includes .NET 2.0 and 3.0) and click on OK. The installation process will take a few minutes to complete, depending on the speed of your connection.
Did it work? Great, you’ve beaten error code 0x800F081F.
