Unadorned options anywhere on the command line are parsed by getopt, which is 
why the options are quoted by cron-config:

$ awk '/cygrunsrv\s-I/,/[^\\]$/' /usr/bin/cron-config
                 if cygrunsrv -I cron -p /usr/sbin/cron -e CYGWIN="${cygenv}" -e 
TMP="/tmp" \
                     -e TEMP="/tmp" -a "-n" -d "Cron daemon" -u "$cyg_username" 
-w "$password"
                 if cygrunsrv -I cron -p /usr/sbin/cron -e CYGWIN="${cygenv}" \
                     -a "-n" -d "Cron daemon"

I have normally found it more useful to run Cygwin *-config as elevated admin, 
and if from cmd with Cygwin /bin/ in path, then as `bash -c /usr/bin/*-config`.

You can modify settings either with:

	$ cygrunsrv -E $srv; cygrunsrv -R $srv; cygrunsrv -I $srv ...

possibly adding:

	-d, --disp "CYGWIN Cron daemon"
	-c, --chdir `cygpath -m /`
	-O, --preshutdown
	-y, --dep syslog-ng ...

or with:

$ sc config help
DESCRIPTION:
         Modifies a service entry in the registry and Service Database.
USAGE:
         sc <server> config [service name] <option1> <option2>...

OPTIONS:
NOTE: The option name includes the equal sign.
       A space is required between the equal sign and the value.
       To remove the dependency, use a single / as dependency value.
  type= <own|share|interact|kernel|filesys|rec|adapt|userown|usershare>
  start= <boot|system|auto|demand|disabled|delayed-auto>
  error= <normal|severe|critical|ignore>
  binPath= <BinaryPathName to the .exe file>
  group= <LoadOrderGroup>
  tag= <yes|no>
  depend= <Dependencies(separated by / (forward slash))>
  obj= <AccountName|ObjectName>
  DisplayName= <display name>
  password= <password>

for example:

$ sc cron config start= delayed-auto DisplayName= "CYGWIN Cron daemon" \
	depend= syslog-ng

or

$ s=/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/cron; \
   regtool set -d $s/KEY DWORD-VALUE; \
   ...

giving something like:

$ s=/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/cron; \
   for p in {'',/Parameters{,/Environment}}; do \
	echo; echo $s$p:; regtool list -v $s$p;
   done
