I notice that heci.inf is system driver, It shows 'error removing heci.inf when I try to remove it. You told me not to remove the system driver before, why are you telling me to remove it now?
I suggest removing System drivers as a last resort. The previous output shows the driver is very outdated (10/19/2010), which can cause problems (especially the error code 0xc1900101) during the setup. Removing drivers is a trial-and-error solution because the logs didn't indicate which driver was at fault.
If you can't help me solve the problem that prevented me from completing the in-place upgrade successfully, could you help me solve the problem about Windows 10 cumulative update without losing any data(please help me with a targeted solution as much as possible)?
(I just found all other updates can be successfully installed, but still error in downloading and installing cumulative update)
