经多方测试验证，3CDaemon与Windows 11系统完全兼容。多个软件下载站明确标注其运行环境为“winxp/vista/win7/win8/win8_1/win10/win11”，表明软件已支持Windows 11操作系统。此外，3CDaemon适用于32位和64位的Windows系统版本，大多数常见版本的Windows系统均可运行。
As a lightweight application, it requires very few system resources and runs natively on 64-bit versions of Windows 11. This makes it an excellent choice for use on modern laptops or workstations without impacting overall system performance. However, because it's an older tool that relies on legacy Windows components, certain security features in Windows 11, such as the built-in firewall, may need to be configured to allow the service to communicate freely on the network.
