The final PowerShell Weekly of 2025 is here.

If you’re new: PowerShell Weekly is hand-curated every single week of the year. No bots, no auto-aggregation. I read, select, and organize the content so it’s actually worth your time.

Which is what I take two weeks off at the end of the year to recharge and get ready to do 50 editions again next year.

If you’ve been reading, sharing, or contributing this year, thank you. It genuinely makes the effort worthwhile.

Go check out this last issue of 2025, enjoy the holidays, and I’ll see you back here the first week of 2026.

• SearchScript: Search PowerShell Scripts
  Every once in a while, we've got to search our scripts, often to make a particular update. Sadly, we're often falling back on Select-String to do this. This isn't ideal, because this means we lose the context around our scripts. So why not make a quick tool to search PowerShell ScriptBlocks using the Abstract Syntax Tree?
