Windows question - update file modified date

[Filliam H. Muffman]

I have doubts that any utility can change the dates without the proper privileges.

You either need to find someone with network privileges to modify/write those files to change the dates, or assemble everybody in the IT managers office and don't leave until they/it grants it to someone in your group.
