Hello, How can I select a specific file extension from a directory, such as .AVI, using File Explorer to create a list for later use, without having to resort to the DOS Command Prompt?

Microsoft's ongoing push to make Copilot a first‑class assistant on Windows 11 has taken a conspicuous new turn: preview build artifacts and Insider sleuthing show an invisible “Chat with Copilot” trigger inside File Explorer, along with a “Detach Copilot” affordance that points to a docked...

Microsoft has quietly given Windows 11 users a real way to make the intrusive “AI Actions” entry in File Explorer’s right‑click menu disappear: in Insider Preview Build 26220.7344 Microsoft changed File Explorer’s context‑menu logic so that if there are no available or enabled AI Actions, the...

Microsoft has quietly rolled back the annoying “white flash” in File Explorer’s dark mode: the Patch Tuesday cumulative update KB5072033 corrects a rendering regression introduced by the December preview KB5070311, and also bundles fixes and configuration changes that IT teams need to know about...

Microsoft’s advisory entry for CVE-2026-20932 confirms a Windows File Explorer information‑disclosure defect in the January 2026 update set, but the vendor’s public guidance is deliberately terse and leaves several technical details unverified — forcing administrators to treat the flaw as an...

Thanks to a recent Windows 11 update, you can now shrink image files directly from File Explorer’s Share window before sending them — no extra app, no manual re-save and no fiddly export dialog. The feature is quick, built into the Share workflow, and exposes a simple menu with Original / Low /...
