Trying to exclude Read-Only Mounted VHD\VHDX drives mounted in a directory

[J. Branco]

Disks are mounted read-only in

C:\FADIA-T\VHDM\folder\0\


I've added exclusions for

C:\FADIA-T\VHDM\*\*\*\*


Using MPCmdRun.exe -CheckExclusion -path "C:\FADIA-T\VHDM\folder\

Using MPCmdRun.exe -CheckExclusion -path "C:\FADIA-T\VHDM\folder\0


each shows excluded


but the sub-folder (root of the mounted VHD) returns not excluded with "C:\FADIA-T\VHDM\folder\0\folder\ [Device\HarddiskVolume#\] is not excluded.


I am not concerned about scanning these VHD(x)'s because they are created on a mostly secure capture machine.


My apps that are in these VHD's run incredibly slow since switching to MS Defender with ATP. I don't need these files scanned when the disks are mounted or content is accessed


I can't find a way to tell Defender to not scan these Virtual disks or paths.



Microsoft had a similar problem with FSLogix but somehow fixed with a definition update.
