Issue: How to fix Windows 10 update error 0x800f081f?

Tried to install Cumulative Update KB4074588, but it eventually ended up with an error code 0x800f081f. Ran Windows Update Troubleshooter, but it did not help. What could you recommend?

Solved Answer

The Error Code 0x800f081f belongs to the group of Windows Update[1] error based on the circumstances it occurs. Although the similar combination of numbers can show up while installing Microsoft .NET Framework 3.5 on Windows,[2] they denote different system's problems.

The Windows Update error 0x800f081f usually prevent Windows 10 users from installing Cumulative Updates, which are released by Microsoft on a regular base to carry out new features and apply security patches,[3] bug fixes, and similar improvements. The following are the Cumulative Update versions that could not be installed by many Windows 10 users due to the 0x800f081f:

KB4058258
KB4090913
KB4056892
KB4051963
KB4048955
KB4074588

The latest instance of the 0x800f081f bug is related to the 2018-02 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4074588). Just like with the previous examples, the error does not allow the update to be installed, which gets stuck at some point and then reverts all the initiated changes.

Error code 0x800f081f

The culprit of the 0x800f081f Cumulative Update Error is usually related to corrupted system's files. Windows Update components are the leading player in this game, so you should try to reset these components.

According to some Windows 10 enthusiasts, the culprit of the problem may be related to duplicate patches. In other words, the previous updates might have already patched specific system's errors, and the one you attempt to install cannot be overwritten.

Sometimes, cumulative updates cannot be installed due to the conflict with anti-virus and Windows Firewall,[4] so we would recommend disabling then and trying to install the required update again. In case the update still fails, try to fix the 0x800f081f error by following these methods. 

TIP: before you skip to the advanced methods, we would highly recommend scanning the system with Reimage optimization utility to address corrupted system's files, malware or other vulnerabilities that may trigger 0x800f081f error.
