Hardware Fingerprinting
Games and anti‑cheats collect unique identifiers from your CPU, GPU, motherboard, disks, network adapters, and Windows installation to build a hardware profile.
HWID Bans & Hardware Identification – How They Work
Hardware ID (HWID) bans tie a ban to your physical hardware rather than just an account. Understand how games fingerprint your machine, what identifiers they collect, and how the research community studies these systems.
How HWID Bans Work
Ban Persistence
Unlike account bans, HWID bans persist across new accounts. If your hardware fingerprint matches a banned profile, you’re blocked before you even log in.
Detection Vectors
Common vectors: disk serial numbers, motherboard UUID, MAC addresses, GPU serial, Windows Machine GUID, TPM data, and SMBIOS tables.
What Gets Fingerprinted
Disk Serials
NVMe/SATA serial numbers are one of the most common HWID sources. They’re unique to each drive and easy for anti‑cheats to query via WMI or DeviceIoControl.
Network Identifiers
MAC addresses and adapter GUIDs provide network‑level fingerprinting. Some anti‑cheats also check adapter names and driver versions.
Windows Identifiers
Machine GUID, product ID, computer SID, and registry‑stored installation data all contribute to the fingerprint. Reinstalling Windows alone often isn’t enough.

⚠️ Legal & Ethical Note: HWID spoofing to evade bans violates virtually every game’s Terms of Service and may violate computer fraud laws in some jurisdictions. These articles are for educational research only — understanding how systems work, not circumventing them.
Frequently Asked Questions
Can I get HWID banned from a single-player game?
It's rare but possible. Most HWID bans come from online multiplayer anti-cheats (EAC, BattlEye, Vanguard, RICOCHET). Single-player games rarely implement hardware fingerprinting.
Does changing one component remove an HWID ban?
Usually not. Anti-cheats collect multiple identifiers and use fuzzy matching — changing just your disk or MAC address may not be enough if other components still match the banned profile.
What is a HWID spoofer?
A tool that intercepts the system calls anti-cheats use to read hardware identifiers and returns fake values. They typically run at kernel level (as drivers) to intercept low-level queries. They're studied for research purposes.
Is HWID spoofing legal?
Spoofing itself isn't illegal in most jurisdictions, but using it to circumvent bans violates Terms of Service (a contract). In some cases it could intersect with computer fraud statutes. This is not legal advice — consult a professional.
