Grzegorz,

I've had great luck using both versions of CRON found here:

http://www.kalab.com/freeware/cron/cron.htm

I prefer these native versions to PyCron since they don't require a Python
installation.

For running WPKG, I use the crons.exe version which installs itself as a
service.  After copying crons.exe and a crontab file to C:\WINDOWS\SYSTEM32,
I just run these two commands:

c:\windows\system32\crons.exe /install
c:\windows\system32\sc.exe start CRON

And here is an example of the crontab that I use (look out for wrapped lines
below):
-----------------------------------------------------
# Basic crontab format:
#
# +---------------- minute (0 - 59)
# |  +------------- hour (0 - 23)
# |  |  +---------- day of month (1 - 31)
# |  |  |  +------- month (1 - 12)
# |  |  |  |  +---- day of week (0 - 6) (Sunday=0)
# |  |  |  |  |
# *  *  *  *  *  command to be executed

# refresh the crontab file every 10 minutes
0,10,20,30,40,50 * * * * c:\windows\system32\xcopy.exe /y "\\
fully.qualified.domain.name\NETLOGON\APPS\cron\crontab"
"c:\windows\system32"

# run wpkg.bat at 10pm, midnight, and 2am each day
0 22,0,2 * * * c:\windows\system32\cmd.exe /c \\fully.qualified.domain.name\
NETLOGON\APPS\wpkg\wpkg.bat
-----------------------------------------------------

That website also has a cron.exe version which can be run as the logged-in
user, but for running WPKG, I prefer to have the CRON service run as the
system user and just grant "Domain Computers" read/execute access to
%SOFTWARE%.

Cheers,

Troy
