What to do if KB4056892 won’t install properly on your Windows device

If you’re having problems with KB4056892, chances are that Windows Update did its thing and said it needed to reboot. Once restarted, the message that your system needs to be restarted doesn’t go away. No matter how many times you reboot, the message remains.

It doesn’t stop your device working and doesn’t get in the way of you using it, but it is a pain.

How to fix KB4056892 not installing properly on your Windows device

There are a couple of tried and tested fixes for any Windows Update that doesn’t go according to plan. The first is to reset Windows Update and the second is to apply the individual update manually. There are a couple of other things you can do if they don’t work.

First, try this. Follow these steps exactly:

  1. Right click the Windows Start button and select Command Prompt (Admin).
  2. Type ‘net stop wuauserv’ and hit Enter.
  3. Type ‘net stop cryptSvc’ and hit Enter.
  4. Type ‘net stop bits’ and hit Enter.
  5. Type ‘net stop msiserver’ and hit Enter.
  6. Type ‘Ren C:WindowsSoftwareDistribution SoftwareDistribution.old’ and hit Enter.
  7. Type ‘Ren C:WindowsSystem32catroot2 Catroot2.old’ and hit Enter.
  8. Type ‘net start wuauserv’ and hit Enter.
  9. Type ‘net start cryptSvc’ and hit Enter.
  10. Type ‘net start bits’ and hit Enter.
  11. Type ‘net start msiserver’ and hit Enter.

I use this a lot to troubleshoot Windows Update. Essentially what you’re doing is stopping all services associated with Windows Update. You then rename the two update data folders and restart Windows Update services. This causes the system to download fresh copies of all files and start again. This works for the KB4056892 and also for many other issues to do with Windows Update.

If that doesn’t work, you can apply the update manually.

  1. Visit this web page on the affected device.
  2. Download the correct update for your operating system.
  3. Double click the executable file and allow it to install.
  4. Reboot when required.

I don’t usually recommend manually updating Windows but in this instance I will make an exception.

If that doesn’t work, we need to perform a System File Check and then run the Deployment Image Servicing and Management tool (DISM). I use these tools a lot as they are very effective at fixing all manner of Windows core file issues.

  1. Right click the Windows Start button and select Command Prompt (Admin).
  2. Type ‘sfc /scannow’ and hit Enter.
  3. Allow the process to complete.
  4. Type ‘DISM /Online /Cleanup-Image /RestoreHealth’ and hit Enter.
  5. Allow the process to complete.

System File Checker runs a comparison of Windows files installed on your computer and those in an index it holds on what should be there. If it finds any discrepancies, it will alert you and offer to fix them. If a corruption or missing file is what is stopping Windows Update, this fixes it.

DISM is a Windows imaging tool that allows us to check the installed version of Windows against what it should be and make any repairs it think necessary. The RestoreHealth switch is what allows it to perform automatic repairs. This saves you having to agree all fixes and lets DISM just get on with the job.

Arguably, if KB4056892 just contains quality of life fixes you don’t need to install it at all. However, if you’re seeing this error, Windows Update has already tried to install it so you are stuck. The steps listed in this tutorial should be enough to fix the problem so it doesn’t happen again.
