Windows 7 update KB4523206 fails with the error code 80242016. According to this post some others have the same problem. However, no solution has been provided at the moment. How can I install the update?


With the help from an old page at Answers.Microsoft (2009)

Windows Update error code 0x80242016 = WU_E_UH_POSTREBOOTUNEXPECTEDSTATE The state of the update after its post-reboot operation has completed is unexpected.

(ie., Some software can be stopping the update before the machine is being rebooting, not allowing it to complete properly.)


I suggest you check for malware / virus's, etc., stop or uninstall any 3rd party firewalls.

Create a shortcut on your desktop using the system Cleanup Manager:


Right-click the Icon and choose Run As Adminstrator and choose (C:) Let it run through the process and it should give you an options box Check the boxs

[x] Service Pack and Backup Files [x] Windows Update Cleanup <-- You might not find this listed

If you have never run Cleanup before it will probably take a while to finish...

Then try running the "Deployment Image Servicing and Management".

DISM /Online /Cleanup-Image /ScanHealth

Enter your Temp folder (both in User.... and Windows\Temp and remove older files (older than a week, maybe even older than two days).


Hope this helps.

  • Thanks! We had yesterday one optional update and received today two new updates (1 required, 1 optional). After installing them and running Cleanup Manager as suggested above the update KB4523206 installed successfully. – haba713 Nov 19 '19 at 11:15
  • That's great, happy it worked out for you. You now might want to defrag your hard disk(s). – vssher Nov 19 '19 at 16:36
