kb4556799

The May Patch Tuesday Updates have just arrived, but it seems that not everyone has the chance to get it.

Several users have been reporting that they are having issues with installing the new update, particularly those running Windows 10 versions 1909 and 1903 that received the KB4556799 cumulative update.

One user stated that:

2020-05 Cumulative Update for Windows 10 version 1903 for x64-based Systems (KB4556799) Error 0x800f0831 fails.

Also, DISM.exe /Online /Cleanup-image /Restorehealth Gets to 99.4% and stops.
Error: 0x800f081f
[…]

Other users reported that they too have similar issues with not being able to update, only that they are receiving a different error code:

When i try to install the update its says me:
2020-05 Actualización acumulativa para Windows 10 Version 1909 para sistemas basados en x64 (KB4556799)
Error 0x80070308
I have my windows on spanish but is a acumulative updates

Users can still follow a few troubleshooting steps to stop this problem

While it may be indeed one of the first times users have faced error code 0x800f081f, we can’t say the same thing about error code 0x80070308. Apparently, this is an issue that plagued Windows 7 users in the past as well.

However, these types of errors are common enough that over time plenty of solutions have been found to fix them. these include:

  • Running the Windows Update Troubleshooter
  • Stopping the Windows Update service from the Task Manager
  • Deleting all the files from the C:WindowsSoftwareDistributionDownload folder
  • Resetting Windows Update Service, and more…

One thing worth mentioning is that both of these errors happened while updating via the Windows Update menu. However, keep in mind that Patch Tuesday updates can also be downloaded via the Windows Update Catalog or through the Windows Server Update Service.

We’ve also written an article that has direct download links to each cumulative update, as well as a short changelog for each of them.

All in all, those who did manage to get the new update installed should now enjoy improved security, especially since Microsoft introduced a new feature that filters apps base don their reputation.

More so, gamers should also see a boost to their system with the new Windows Display Driver Model (WDDM) 2.7.

What’s your take on this new update for Windows 10 version 1909 and 1903?
