KB5012599 downloads 100%, then after a period of inactivity it pauses at Installing 20% for an extended period of time, after which it shows that it has installed 100%, but about a minute after that it generates the 0x800f0831 error with matching failure to install message.
I have spent the last 2 hours trying to fix this problem, including running the Windows Update Trouble Shooter plus a host of other suggestions, but nothing works.
Never had any issues with Windows 10 updates till now.
I don't know what to do.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Latest from Microsoft is that we will need to install the May Cumulative update to fix this, basically skip the Windows 10 April cumulative update. There will not be a specific fix or new release of 5012599. Not great as a large number of devices did not get updated in April so theoretically vulnerable.
Setting the states of affected packages in KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\ to 0 worked for me. However what exactly does this do?
Yup. I tried this after spending a lot of time on the other approaches, and it worked for me too.
EVERYONE - If u want to fix this, do an in place upgrade using windows installation media tool on their website! It worked for me and now it says up to date on my pc!
Congratulations! Proves there‘s more than one way to skin the proverbial cat.
