I googled up this documentation which states "All subdirectories in the
directory path you specify will also be excluded."
 https://docs.trendmicro.com/all/smb/wfbs-services/server/wfbs-svc/v3.7/en/docs/WebHelp/_WFBS-SVC/C08-Scans/ExcludingFilesFoldersFromScans.htm

I changed the exclusion to be C:\cygwin64

But I still have no luck in starting XWin.exe, unfortunately.
