automatic deletion from \Windows\SoftwareDistribution\Downloads fo

It was my understanding that when Automatic Updater downloads files and puts

them in this folder (\Windows\SoftwareDistribution\Downloads) that the files

would automatically delete after 10 days. I just had some disk space issues

and found that there were files in the folder going back as far as a year. I

went ahead and deleted them, but is there some setting I need to get these to

delete automatically?

Thanks,

Charlotte
