Setting local account expiry dates
Setting expiry dates on AD accounts is a common occurrence and is well documented. Setting expiry dates on local accounts is also possible
$user = [adsi]"WinNT://./Test1, user"
$expirydate = (Get-Date).AddDays(2)
$user | Format-List *
This uses the WinNT (remember its case sensitive) ADSI connector to get a local account. We then set the AccountExpirationDate property to the desired date – in this case two days from now.
Quick call to SetInfo() and we are done
