+====== Windows 11 to identify which application or process is using a drive and preventing safe ejection ======
+---
+==== Option 1: Built-in Windows Resource Monitor (No Download Needed) ====
+Windows 11 includes a native tool that tracks active disk locks.
+  - Press **Ctrl + Shift + Esc** to open **Task Manager**.
+  - Select the **Performance** tab on the left, then click the **three dots (...)** at the top right and select **Resource Monitor**.
+  - Go to the **CPU** tab.
+  - Expand the **Associated Handles** section.
+  - In the **Search Handles** box, type your drive letter followed by a colon (e.g., ''E:'' or ''D:'').
+  - Look at the **Image** column to see the exact program holding the drive open. You can right-click the process to end it if necessary.
+---
+==== Option 2: Microsoft PowerToys ("File Locksmith") ====
+Microsoft maintains a free tool suite called **PowerToys** that integrates directly into Windows 11.
+  - Download **Microsoft PowerToys** from the Microsoft Store or GitHub.
+  - Ensure the **File Locksmith** utility is turned on in PowerToys settings.
+  - Open **File Explorer** and go to **This PC**.
+  - Right-click the external drive that will not eject.
+  - Select **What's using this file?** (or look under //Show more options//).
+  - A window will list all active processes using that drive, complete with an option to close them instantly.

+==== Option 3: LockHunter or Process Explorer (Free Third-Party Tools) ====
+For more detailed information or lightweight alternatives:
+  * **LockHunter:** A dedicated tool for unlocking files and drives. Right-click any drive in File Explorer, select **What is locking this file/folder?**, and it will display the process, path, and option to close or unlock it.
+  * **Process Explorer (from Microsoft Sysinternals):** A standalone utility provided by Microsoft. Run it as administrator, press **Ctrl + F**, type your drive letter (e.g., ''E:''), and press Enter to search all active system handles.
