Solved - Windows Defender service won't start


on each logon following installation of desktop experience feature (which includes windows defender), following error message appears:

"application failed initialize: 0x800106ba . problem caused windows
defender service stop. start service restart computer or search
, support on how start service manually. "

attempting start windows defender service manually generates following error:

"windows not start windows defender service on local computer.  error 0x80092003: error occurred while reading or writing file."

using process monitor, looked indications of read or write failures, couldn't find definitive.

there way of getting windows defender service start?



solved: happens if %programdata% environmental variable set path other default (c:\programdata).  in case, path d:\programdata.  a closer , process monitor output showed several path not found lines.

even when programdata specified on d: in answer file, windows defender installs files c:\program data.

for now, workaround stick default location of programdata or copy files windows defender installs d:\programdata\microsoft\windows defender.
