+# Add PowerShell 7 to PATH in Windows
+
+This guide will help you add **PowerShell 7** (PowerShell Core) to your system’s PATH variable on Windows, so you can easily run it from any Command Prompt or Run dialog.
+
+## Prerequisites
+
+- You should have **PowerShell 7** installed on your machine. If you haven’t installed it yet, you can download it following the guide here: [Installing PowerShell on Windows | Microsoft Learn](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.5).
+- **Administrative privileges are not required** unless you're modifying system-wide environment variables. You can modify your **user-specific PATH** without admin rights.
+
+## Steps to Add PowerShell 7 to PATH
+
+### 1. Open **System Properties**
+   - Press `Win + X` and choose **System**.
+   - Click on **Advanced system settings** on the left sidebar. This will open the **System Properties** window.
+   - In the **System Properties** window, click on the **Environment Variables** button at the bottom.
+
+### 2. Edit User Environment Variables
+   - In the **Environment Variables** window, under **User variables**, find the `Path` variable.
+   - Select the `Path` variable and click **Edit**. (If the `Path` variable doesn’t exist, click **New** and name it `Path`.)
+
+### 3. Check if PowerShell 7 Path is Already in PATH
+   - Before adding the path, make sure the following path is not already present in the list:
+     ```
+     C:\Program Files\PowerShell\7\
+     ```
+   - If the path is already there, you don't need to add it again.
+
+### 4. Add PowerShell 7 Path
+   - If the path is not already in the list, click **New** in the **Edit Environment Variable** window.
+   - Add the following path to the list:
+
+     ```
+     C:\Program Files\PowerShell\7\
+     ```
+
+   > **Note:** If you installed PowerShell 7 in a custom location, replace the above path with the correct one.
+
+### 5. Save Changes
+   - After adding the path, click **OK** to close the **Edit Environment Variable** window.
+   - Click **OK** again to close the **Environment Variables** window.
+   - Finally, click **OK** to exit the **System Properties** window.
+
+### 6. Verify PowerShell 7 in PATH
+   - Open **Command Prompt** or **Run** (press `Win + R`).
+   - Type `pwsh` and press Enter.
+   - If PowerShell 7 opens, you've successfully added it to your PATH!
+
+---
+
+## Troubleshooting
+
+- **PowerShell 7 not opening:** Ensure the path to PowerShell 7 is entered correctly. If you're using a custom installation folder, check that the correct path is added to the `Path` variable.
+
+- **Changes not taking effect:** Try restarting your computer or logging out and logging back in for the changes to apply.
