How to change the computer icon in WIN10?

Changing the icon for a computer, folder, or application shortcut in Windows 10 is a straightforward process managed through the Properties dialog of the specific object, though the exact steps and available options depend on whether you are altering a system icon like "This PC" on the desktop or a standard shortcut. For a standard shortcut or folder, you begin by right-clicking the item and selecting "Properties." Within the Properties window, navigate to the "Shortcut" tab (for shortcuts) or the "Customize" tab (for folders). Here you will find a "Change Icon" button, which opens a dialog box displaying a library of default icons contained within system files like `shell32.dll` or `imageres.dll`. You can select an icon from this list or browse to a custom icon file, which must be in a supported format such as `.ico`, `.dll`, `.exe`, or `.png`. After selecting the new icon, you apply the changes, and the visual representation updates immediately, provided the file path to the custom icon remains stable.

Altering a core system icon, such as "This PC," "Network," or the Recycle Bin, requires a different pathway through the legacy Control Panel. This is accessed by opening the Settings app, navigating to "Personalization," then "Themes," and selecting "Desktop icon settings." This action opens the "Desktop Icon Settings" window from the Control Panel era. Within this window, you select the specific system icon you wish to modify and click the "Change Icon" button. Similar to the shortcut method, this presents a selection of system icons, and you can browse for a custom `.ico` file. The change is system-wide and persists across user sessions, modifying the icon wherever that system object appears. The mechanism relies on the Windows registry storing the path to the new icon resource, which is why using a permanent file location is critical; moving or deleting the source `.ico` file will cause the icon to revert to a default or display an error.

The primary technical considerations involve icon file integrity and system file permissions. Windows 10 supports multiple image formats for icons, but the `.ico` format is most reliable as it can natively store multiple resolutions (e.g., 16x16, 32x32, 256x256). When using a `.png` or other image file, Windows may attempt to convert it, but results can be inconsistent, especially for smaller icon sizes where detail is lost. A more advanced method involves creating or extracting icons from executable files or dedicated icon libraries. For users seeking to apply changes globally or automate the process, third-party customization software can modify system icons by directly interfacing with system resources and the registry, but this carries inherent risks such as instability or difficulty reverting changes. It is also worth noting that major Windows updates can sometimes reset custom system icons to their defaults, as the update process may restore core system settings.

In practice, the implication of changing icons extends beyond mere aesthetics to user interface clarity and personal workflow organization. For enterprise environments, standardized custom icons can denote specific network drives or critical applications, reducing user error. The process is deliberately segmented by Microsoft into a simple method for user-created shortcuts and a more buried method for system objects, a design choice likely intended to prevent casual users from accidentally altering fundamental system graphics. The stability of the change hinges entirely on the referenced icon file's permanent location, making it advisable to place custom `.ico` files in a dedicated, non-volatile directory rather than a temporary downloads folder. While the graphical user interface for this functionality has remained largely unchanged since earlier Windows versions, it remains a fully supported part of the personalization suite, unaffected by the general migration of settings from Control Panel to the modern Settings application.
