if you download an older update, click on properties, you will see that both the create and modify date match your time of download. Hence, the properties of Windows modules used in the download. Off-topic, well, the topic replies included suggestions from forum members on determination of the file create/modify/accessed dates. If you download an older update, examine the properties, I believe you will see the create/modify dates reflect the download date. Accessed date will be when you examined the properties. BTW, I also use FF and XP.
