Windows 10 Update ( KB4074588 ) Error 0x800f081f Failed to install

I tried to install Windows 10 Update ( KB4074588 ) and got Error 0x800f081f

Can anyone tell anything about it.  I am trying to install my application which has a problem and I have been advised to make sure the Windows updates are all done.

I would like to know as much about this as I can so I can work out if it is likely to affect my application.  I don't want a suggestion for a manual fix as I don't believe I should be doing this on a clients' machine.

Thanks in advance

Hi Clive,
My guess is that you're getting that error because KB4074588 is known to be a bad update. You don't want to install it. In fact, people who have installed it are uninstalling it. All of these relatively recent EE threads discuss it:'t-working-and-Malware.html't-work.html

Microsoft is well aware of the problem (which may be why you got the 0x800F081F error) and even posted an article about it on 23-Feb (updated on 6-Mar) at the Windows support site showing two methods to resolve it:

If you want to install this update, make sure you have the newest .NET framework installed.

Official MS statement:
Even though the update was successfully installed, Windows Update incorrectly reports that the update failed to install. Select Check for Updates to confirm that there are no additional updates available.

You can also type About your PC in the search box on the taskbar to confirm that your device is using the expected OS build.

Microsoft is working on a resolution and will provide an update in an upcoming release.

Thanks Joe.  Very informative.

I don't think it affects my application.

You're welcome, Clive. I'm pretty sure you're right that the lack of that KB is not affecting your application. I would look elsewhere for the problem in installing it. While the advice to make sure that Windows updates are all done is generally good advice, that's likely not the answer this time (and certainly not with respect to KB4074588). Regards, Joe
