When installing the Windows 10 April 2018 Update (1803) the installation fails with error 0x80070241. When installing via SCCM you see the error “The software change returned error code 0x80070241(-2147024319).”
In Event Viewer you see the error “Installation Failure: Windows failed to install the following update with error 0x80070241: Feature update to Windows 10 (business editions), version 1803, en-gb.”
To resolve the issue uninstall the Windows Assessment and Deployment Kit – Windows 10 (ADK).
I am seeing this exact error on my Windows 10 machine but when I run adksetup /uninstall it tells me that it is not installed. Looks like this update has some serious dependency bugs.
