Fastfetch
Fastfetch 2.66.0 is a customizable terminal system-information tool for displaying operating system, CPU, GPU, memory, disk, network and desktop details.
What Fastfetch provides
Fastfetch reads system interfaces and formats an overview of the operating system, host, CPU, GPU, memory, disks, network, terminal and desktop environment. Modules, JSONC configuration and text or image logos make it useful for diagnostics snapshots and asset collection, but it is not a stress test or a professional hardware benchmark.
Output and platform differences
Fields depend on operating-system APIs, permissions, drivers and hardware databases. JSON output is easier for automation than parsing colored terminal text, but scripts should handle missing modules and platform-specific names. A screenshot can expose hostnames, usernames, local addresses and disk paths, so redact those before sharing.
Configuration safety
Ordinary modules mostly read system data, while a Command module can execute a shell command. Review a shared JSONC file line by line before running it, especially when Fastfetch launches on login. Review date: 2026-08-23.

Fastfetch 2.66.0 Windows overview and configuration guide
Run the default overview first, add only useful modules, save a small JSONC configuration and export JSON for automation after the baseline works.
Before you start
- Use the Windows x64 archive in a modern ANSI-capable terminal such as Windows Terminal.
- Save the program and configuration in a normal-user directory; routine system information does not require administrator rights.
- Redact host, user, local IP and disk information before sharing screenshots or configuration files.
Installation steps
- 01
Extract and verify the binary
Unzip the package, open PowerShell in its directory and run the version command to confirm the architecture and release.
- 02
Run the default overview
Execute Fastfetch and check operating system, host, CPU, GPU and memory modules before customizing output.
- 03
Add PATH only when needed
Add the directory to the user PATH for repeated use, and test a temporary invocation before changing a global startup script.
Quick start
- 01
Discover available modules
Inspect the full module set, choose only the fields required for the task and avoid exposing every device identifier by default.
- 02
Generate a minimal JSONC file
Create a configuration, change one module or logo at a time and keep a working backup after each successful run.
- 03
Export machine-readable data
Select modules and output JSON for automation, handling unsupported fields, permission errors and nonzero results instead of parsing screen text.
Usage tips
- Fastfetch supports multiple platforms, but the available fields and names differ across operating systems.
- Test login-time execution for startup cost and ensure it does not pollute non-interactive shell output.
- Remove Command modules, absolute paths and personal identifiers before sharing a configuration.
Troubleshooting and uninstall
Why do the logo or colors look wrong?
Test the default text logo, then check terminal color, font and image-protocol support. Terminal capabilities differ between Windows Terminal and other consoles.
Why is a hardware field empty?
Check drivers and system databases, then compare with a vendor or operating-system information tool. One missing field is not proof of hardware failure.
- Remove automatic startup and PATH entriesDelete Fastfetch calls from PowerShell or terminal startup files first, then remove the user PATH entry and program directory while retaining JSONC when useful.
Frequently asked questions
Is Fastfetch a hardware stress or benchmark tool?
No. It reads and formats system information. Use operating-system and vendor tools for temperatures, stability, stress testing and detailed diagnosis.
Can I use a shared Fastfetch configuration without review?
Review it first. A Command module can run shell commands, and a login configuration can repeatedly execute them or expose local information.
Does the download require an extraction code?
The Quark entry does not require one; the four-character code for the Baidu entry is shown beside its download entry.
