The seemingly straightforward process of installing a Windows update may result in problems that render your system vulnerable and deprived of critical enhancements. One of the causes is the error 0x800f0801, which prevents the downloaded files from being installed on the computer.

When you receive the CBS_E_NOT_APPLICABLE message, it signifies one of two things: either the update cannot be installed on this machine or the system is unable to handle the update.

In this article, we will discuss how to resolve the Windows 11 update error 0x800f0801 by implementing a few straightforward options. But first, let’s understand what has caused this issue to happen in the first place.

What causes the 0x800f0801 error to occur?

It is possible to receive an error code of 0x800F081F, which is one of four possible error codes, all of which indicate the same underlying problem. The other three error codes are 0x800F0906, 0x800F0907, and 0x800F0922, which are all related to the same thing..net  windows 11 error code 0x800f0801

Each of these error codes is caused by incompatibilities with the Microsoft.NET Framework 3.5. Typically, they will occur when you enable the framework using the installation process, the Deployment Image Servicing and Management (DISM) tool, or through the use of Windows PowerShell.

The codes will only appear on Windows 11, Windows 10, Windows Server 2012 R2, and Windows Server 2012. They will not appear on any other versions of Windows.

Microsoft.NET Framework 3.5 is available as a Feature on Demand on the operating systems listed above (i.e., it is not enabled by default).

When you enable this feature, Windows Update attempts to download .NET binaries, as well as any other required files from the Internet. It is possible that you will see the codes if your machine is not properly configured. Here’s a list with the codes and what they mean:

  • 0x800F081F: In order for the installation to begin, Windows could not locate any.NET source files to work with.
  • 0x800F0906: Windows was unable to download the.NET source files, connect to the Internet, or install a role, role service, or feature because it could not connect to the internet or download the.NET source files.
  • 0x800F0907: Your network policy settings may have blocked Windows from connecting to the Internet because the DISM program did not work.
  • 0x800F0922: The processing of .NET advanced installers or generic commands failAttempts to process.NET advanced installers or generic commands were unsuccessful.
