## Instructions

### Download and Run the Script

To download and execute the script with one command, follow these steps:

1. **Open PowerShell as Administrator:**

   - Right-click on the Start menu and select “Windows PowerShell (Admin)” or “Windows Terminal (Admin)”.

2. **Execute the Following Command:**

   ```powershell

   Invoke-WebRequest -Uri "https://raw.githubusercontent.com/ignatiosdev/Excel-Multiple-File-Opening-Fix/main/script.ps1" -OutFile "script.ps1"; .\script.ps1

### **How It Works**

This PowerShell script fixes the delay experienced when opening multiple Excel files from Windows File Explorer while another Excel instance is already running.

#### **How It Works:**

1. **Registry Paths**: The script updates specific registry keys related to Excel's Dynamic Data Exchange (DDE) settings:

   - `HKEY_CLASSES_ROOT\Excel.Sheet.12\shell\Open\ddeexec` (for Excel 2013 and newer)

   - `HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open\ddeexec` (for Excel 97-2003)

2. **Registry Updates**: It sets the `Default` value of these keys to `[open("%1" /ou "%u")]`, optimizing the way Excel handles file openings via DDE, leading to faster performance when opening multiple files.

3. **Path Creation**: If the specified registry paths do not exist, the script creates them to ensure that the necessary registry structure is in place.

#### **Why the Bug Happens:**

The issue arises due to outdated or incorrect DDE settings in the Windows Registry. DDE is a protocol used for inter-process communication and can sometimes become misconfigured, causing delays in opening files when multiple Excel instances are involved.
