Windows server local account audit script

Hi guys

I have a requirement from my customer, to send a monthly report of local accounts on a windows servers. I have been able to do this, from a script I found from google. The only problem is, they are requesting to have more column of the existing report. Specifically, they want another 2 columns

1 - When last password changed?
2 - How many days after last password changed?

Here is the script that I've been using, not sure if the owner of the script is in this forum too, thank you so much!
