PowerToys Peek is a lightweight Windows productivity feature that lets you preview files instantly—without opening Excel, Word, Photos, or other heavy apps.

With a simple shortcut, Peek shows the file content in a clean overlay window. Once you’re done, it disappears instantly, keeping your desktop and workflow focused.

This is extremely useful when working with:

• Multiple similar files (reports, screenshots, exports)
• Log files or text files
• Images and PDFs you only need to glance at
• Large folders where opening each file is disruptive

✅ Benefits

• Saves time by avoiding unnecessary app launches
• Keeps your desktop and taskbar uncluttered
• Faster file identification and decision‑making
• Improves focus during analysis or cleanup tasks

🛠️ Procedure

1. Install PowerToys

• Download Microsoft PowerToys from the Microsoft Store
• Launch PowerToys after installation

2. Enable Peek

• In PowerToys, go to File management → Peek
• Turn Peek ON
• Confirm the shortcut (default: Ctrl + Space)

3. Preview Any File

• Release the keys to close the preview instantly
