I also had 0x80070001 errors when I was using a RamDisk with drive letter B: and with my user temp dir to B:\Temp. (I never modified the System temp var; it's still %SystemRoot%\TEMP) ImDisk ToolKit 20170706 (NTFS, Allocate Memory Dynamically, launch at Windows Startup, Create TEMP Folder; nothing Advanced) I'm currently running 64-bit Windows 10 Enterprise 1803 (OS Build 17134.228) Introducing a new variable seems to have resolved my Windows Update difficulty: I ran "SystemPropertiesAdvanced.exe"...
