Cron job for php on windows?

I’d like to run a small php script every 10 minutes or so on my host machine, and unfortunately it runs on non-administrator windows-xp (but i works fairly well, php+mysql) and I can’t change that.

Is there a way, other than a scheduled task, to run a ‘cron’ job on windows ? A php deamon or something ?

I use cmdow (http://www.commandline.co.uk/cmdow/ free) to run background/hidden .BATs, but the php thing is puzzling me a bit

any ideas ?
