==== How to run a crontab in Cygwin on Windows ====
Just to mention first that you could bypass cron altogether with this little trick:\\
Create a scheduled task with the windows scheduler by calling the shell program
<code>
C:\\cygwin\\bin\\bash.exe -l -c /cygwin/path/to/shell
</code>
**otherwise...**
  *  Install cygrunsrv and cron packages from the admin bundle (with 'Install from internet" option)
  *  From a Cygwin prompt, to install the cron daemon as a service type:
<code>
cygrunsrv --install cron --path /usr/sbin/cron --args -n
</code>
  *  Start the cron daemon from a Windows prompt with:
<code>
net start cron
</code>
or from a Cygwin prompt with:
<code>
cygrunsrv --start cron
</code>
Now change the properties on the service to run as a user other than "Local System"
=== Configure cron ===
Run this from a Cygwin terminal
<code>
cron-config
</code>
Show system log of possible problems from the cron daemon (service)
<code>
/usr/bin/cronevents
</code>

==== Diagnose problems ====
Check installed modules
<code>
cygcheck.exe -c
</code>
Check current status
<code>
cygrunsrv -Q cron
</code>
If you get
<code>
(CRON) error (can't switch user context)
</code>
this means that the cron service is trying to run jobs as the "Local System" account. Right-click on the service and change the user it runs jobs as to be the one you want.
