Guess first, no penalty. An AI script should disable accounts nobody has used in 90 days. Its key line is $cutoff = (Get-Date).AddDays(90). It runs with no error. What happens?
PowerShell is the command language Windows admins use to make changes in bulk. Active Directory (AD) holds your company's user accounts. AI can write a script for both in seconds, and the script runs with your permissions.
One missing minus sign. No error, no warning. Monday morning, nobody can sign in.
Worked example
Antes e depois
The AI's script, then the safer version. Highlights show what changed.
AI script
$cutoff = (Get-Date).AddDays(90) Get-ADUser -Filter * -Properties LastLogonDate | Where-Object { $_.LastLogonDate -lt $cutoff } | Disable-ADAccount
Three changes:
- The cutoff is 90 days in the past.
- It only looks at enabled staff accounts in one OU (a folder of accounts), so admin and service accounts elsewhere are left alone.
-WhatIf"Displays a message that describes the effect of the command, instead of executing the command" (Microsoft Learn). You read the list before anything changes.
