How to Fix Update Error 0x800f081f in Windows 10

If you're getting error 0x800f081f when trying to update your operating system, you won't get important system updates. This article will show you several methods to fix this error.

Error 0x800f081f

What Causes Error 0x800f081f

You may experience error 0x800f081f due to incompatibility issues caused by Microsoft .NET Framework 3.5. It has been determined that such incompatibilities occur when users enable NET Framework.

In Windows 10, NET Framework works as an on-demand feature, meaning that when the user turns it on, the Windows Update service tries to acquire the binaries of .NET and other files. If your computer has been incorrectly configured, you will get the 0x800f081f error because Windows Update cannot find the necessary files for NET.

If Microsoft NET Framework is the cause of error 0x800f081f, then you may be able to resolve the issue by using an offline NET Framework installer or enabling the currently installed NET Framework version manually. NET Framework can be enabled using a PowerShell Command, the Deployment Image Servicing, and Management tool, or the installation wizard.
