Windows 10: Update for Windows 10 Version 1803 error 0x80070643 - Event logs show cannot start sedsvc

Get 2018-12 Update for Windows 10 Version 1803 for x64-based Systems (KB4023057) - Error 0x80070643

When attempting to install update. The Event viewer has

Product: Update for Windows 10 for x64-based Systems (KB4023057) -- Error 1920. Service 'Windows Remediation Service' (sedsvc) failed to start. Verify that you have sufficient privileges to start system services.


The program files\rempl folder does not contain sedsvc.exe and associated files. I have another win 10 computer that does contain sedsvc.exe.

The Update troubleshoot and repair tools did not help.

error 0x80070643 (update)

Hey

Try to apply the update manually As suggested by Microsoft. I just wrote a
step by step guide.

However be sure that the update itself is downloaded and that the installation part is failing, and not the downloading part.

Hope it helps you

 

Strange 2.9.0 error message

What is your Windows OS version - Windows 10 Fall Creators Update from Fall of 2017 (version 1709), or is it latest one from April 2018? (version 1803)
Try updating to latter if you use the former.

Also, if you quit and run GPU-Z again 10-20 more times, does it show same error every time?
