Windows 10 May 2023 Update KB5026435 Fails with error 0x80073701

I have updated my windows 10 laptop last week (the update was recommended) and since then it keeps shutting down randomly.

I noticed that there was also an optional update that was not installed and when I tried to do so it fails every time. From what I have red on specialized blogs and forums, this update might be the cause for the random shut downs.

I have tried the following without success:

  • 1 Check internet connection
  • 2 Free up some disk space
  • 3 Try to install the Windows update again
  • 4 Start windows clean boot State
  • 5 Try Windows Update Troubleshooter
  • 6 Reset Windows Update cache
  • 7 Switch google DNS
  • 8 Repair Corrupted Windows System Files
  • 9 Update Windows 10 Offline

Nothing worked.

When I started windows in a clean boot State, the internet adapter was not avalable at all so no internet and impossible to run the update manager...

Any thoughts on how I can fix this?

    What is the way you try to update, manual or auto-update?

    You can try to install the update manually under this link:

    If that doesn't work, I recommend that you collect the following logs to identify the problem: windowsupdate.log,CBS.log.

    Please refer to :

    Hi Kiril,

    Issue: Windows Update based on article KB5026435, May 10<sup>th</sup>, 2023, fails to install with an error 0x80073701.

    Observation: We tried to Update Windows via optional Updates using Advanced options in Windows Updates under settings. The Windows Update fails to install with an error code 0x80073701 and resulted in random shutdowns. It seems that you are not connected to a Wi-Fi connection. We also observed red {marks/indication} on specialized blogs and forums. We tested windows in a clean boot, but internet adapter was not available, then we couldn’t run an update manager in Settings.


    Please refer a KB article mentioned below before proceeding with troubleshooting.
