I have tried multiple methods for updating to Feature Update 2004, including Windows Update and the Windows 10 Update Assistant. The download completes fine and the updates begin to install. The first reboot seems to go OK as well. But then it reboots to a BSOD with Stop code: MEMORY_MANAGEMENT. After that, it rolls back the installation to 1909. The only error in the event log is "Installation Failure: Windows failed to install the following update with error 0xC1900101: Feature update to Windows 10, version 2004." I have run both pre-boot and post-boot memory diagnostics from both Microsoft and Dell. They find no errors. I have tried removing all peripherals from the computer during the update process. I have gone through the Windows Update troubleshooter. I have run sfc. I am stumped.
