Automating tasks on Windows with PowerShell
What you do by hand once is fine; what you do by hand every week, automate it.
PowerShell is the serious way to automate Windows: it works with objects, not text, and that makes it very powerful for administration.
A first useful script
Clean up temporary files older than 7 days:
Get-ChildItem $env:TEMP -Recurse |
Where-Object { $_.LastWriteTime -lt (Get-Date).AddDays(-7) } |
Remove-Item -Force -ErrorAction SilentlyContinue
Why objects and not text
On Unix you chain text with grep/awk. In PowerShell you pass objects through the pipe, so you can filter by real properties (LastWriteTime, Length…) without parsing fragile strings.
Taking it to production
- Schedule the script with Task Scheduler.
- Log what it does.
- Sign your scripts and adjust the Execution Policy instead of disabling it entirely.
Automating isn't just saving time: it's making the task run the same way every time, with no forgetting.
