How to Change the Default Web Browser on Windows 11

Windows 11, like previous versions of Windows, allows you to set your preferred web browser as the default. By default, Microsoft Edge is the web browser, but you can change this to any browser of your choice, such as Google Chrome, Mozilla Firefox, or others. This guide will show you how to change the default web browser in Windows 11.

3. In the pop-up window, select your preferred browser and click OK.
4. Repeat this for all file types (e.g., .htm, .html, .pdf, HTTP, HTTPS, etc.) to fully set your browser as the default for all web-related tasks.

How to Show File Extensions on Windows 11

By default, Windows 11 hides file extensions for known file types, meaning you cannot see the ".txt", ".jpg", ".exe", or other extensions next to file names. However, showing file extensions can be important when you need to identify the type of file you're working with, especially for tasks like troubleshooting or ensuring file security. This guide will show you how to enable file extensions so that they are visible in Windows 11.

Method 1: Show File Extensions via File Explorer

The easiest way to show file extensions in Windows 11 is by using File Explorer’s settings.

Step 1: Open File Explorer
1. Press Windows + E on your keyboard to open File Explorer.

Step 2: Open View Options
1. In the File Explorer window, click the View button on the top toolbar.
2. Hover over Show, then click on File name extensions.

This will immediately make file extensions visible for all file types. For example, a "document" file that was previously displayed as `document` will now be shown as `document.txt`.

Method 2: Show File Extensions via Folder Options

You can also enable file extensions through the Folder Options menu in File Explorer.

Step 1: Open File Explorer Options
1. Press Windows + E to open File Explorer.
2. Click on the three-dot menu in the top-right corner and select Options.

Step 2: Change Folder Options
1. In the Folder Options window, go to the View tab.
2. Under the Advanced settings section, look for the option labeled Hide extensions for known file types.
3. Uncheck the box next to Hide extensions for known file types.
4. Click Apply and then OK.

After applying this setting, file extensions will be visible for all files in File Explorer.

Method 3: Show File Extensions via Control Panel

Another method to make file extensions visible is by using the Control Panel.

Step 1: Open Control Panel
1. Press Windows + S to open Windows Search, then type Control Panel and press Enter.
2. In the Control Panel, click on Appearance and Personalization.

Step 2: Open File Explorer Options
1. Under the Appearance and Personalization section, click File Explorer Options.
2. In the File Explorer Options window, go to the View tab.

Step 3: Change File Extension Settings
1. Under the Advanced settings section, uncheck the box next to Hide extensions for known file types.
2. Click Apply and then OK.

This method achieves the same result as the previous methods but through the Control Panel interface.

Why Should You Show File Extensions?

Showing file extensions can be important for several reasons:
- File identification: You can easily identify the type of file by its extension, such as `.jpg` for images, `.exe` for executable programs, or `.docx` for Word documents.
- Security: Some malicious files disguise themselves as other file types. For example, a file might appear as `document.pdf` but could actually be `document.pdf.exe`, which is an executable file. Seeing file extensions helps avoid accidentally running malicious programs.
- File conversion: When converting files manually (e.g., renaming a `.txt` file to `.html`), showing extensions helps ensure the correct file type.

How to Hide File Extensions Again

If you want to hide file extensions again, simply reverse the process:

1. Open File Explorer and click View on the top toolbar.
2. Hover over Show, then uncheck File name extensions.

Alternatively, you can go back to Folder Options and check the box next to Hide extensions for known file types.

Conclusion

Showing file extensions in Windows 11 is a simple and useful way to better understand and manage your files. Whether you enable this feature through File Explorer, Folder Options, or the Control Panel, being able to see file extensions can help you identify file types, improve security, and ensure you are working with the correct files.
