How to fix NET Framework 3.5 error 0x80070422

How to fix NET Framework 3.5 error 0x80070422.  Error code 0x80070422 is commonly encountered by users trying to apply the latest updates. Problems can also arise when they upgrade from a previous version of Windows to a newer version (for example from Windows 8 to Windows 10), as well as while trying to update or get apps in the Microsoft Store.

Updates are essential not only to fix bugs, improve performance and stability, but also to patch critical vulnerabilities. As a result, persistent errors (like 0x80070422) that prevent Windows updates from being applied can cause serious security problems.

Follow the steps in the guide below to fix error 0x80070422 in Windows 10.

Try the DISM method to enable .NET Framework 3.5 on your system. 

1. Run the following DISM command (image mounted to the c:\test\offline folder and the installation media in the D:\drive) to install .NET 3.5:

   DISM /Image:C:\test\offline /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs
   

   Use /All to enable all parent features of the specified feature.

   Use /LimitAccess to prevent DISM from contacting Windows Update/WSUS.

   Use /Source to specify the location of the files that are needed to restore the feature.

   To use DISM from an installation of the Windows ADK, locate the Windows ADK servicing folder and navigate to this directory. By default, DISM is installed at C:\Program Files (x86)\Windows Kits\8.0\Assessment and Deployment Kit\Deployment Tools\. You can install DISM and other deployment and imaging tools, such as Windows System Image Manager (Windows SIM), on another supported operating system from the Windows ADK. For information about DISM-supported platforms, see DISM Supported Platforms.

2. Run the following command to look up the status of .NET Framework 3.5 (offline image mounted to c:\test\offline):

   DISM /Image:c:\test\offline /Get-Features /Format:Table
   

   A status of Enable Pending indicates that the image must be brought online to complete the installation.

Using DISM with no Internet connectivity

You can use DISM to add .NET Framework 3.5 and provide access to the \sources\SxS folder on the installation media to an installation of Windows that is not connected to the Internet.
