How to Change the Name of Your Computer (Windows, Mac & More)

Your computer's name is more than a label — it shows up on networks, in system settings, remote desktop connections, and shared folders. Changing it is straightforward on most operating systems, but the exact steps, timing, and potential side effects vary depending on your setup. Here's what you need to know.

Why Your Computer Name Matters

Every device on a network gets identified by a hostname — the human-readable name that distinguishes your machine from others. When you connect to a home network, join a workplace domain, or set up file sharing, that name is what other devices and users see.

A generic name like DESKTOP-A7KX39 is perfectly functional, but a descriptive name like Sarahs-MacBook or Office-Workstation-2 makes network management, remote access, and troubleshooting significantly easier.

The name also appears in:

• Network discovery panels on other devices
• Remote Desktop and SSH connection references
• System logs and diagnostic reports
• Bluetooth pairing screens (on some systems)

How to Change Your Computer Name on Windows 🖥️

Windows gives you two main paths to rename your PC.

1. Open Settings → System → About
2. Click Rename this PC
3. Enter the new name (letters, numbers, and hyphens only — no spaces)
