What Is a HWID? Hardware IDs and HWID Bans Explained

When people talk about getting “HWID banned”, they mean the game has banned their computer rather than just their account. To understand why that is hard to shake off, it helps to know what a hardware ID actually is.

What a HWID is

HWID stands for hardware ID. Every component in a PC reports identifying information about itself, much of it including a serial number set at the factory. Taken together, those identifiers describe one specific machine.

There is no single HWID built into Windows. Each anti-cheat decides which identifiers to read and how to combine them into a fingerprint of the PC.

What makes up a hardware ID

The TPM is the newest and strongest entry. Its factory-made key is extremely hard to fake, which is one reason anti-cheats increasingly ask for TPM 2.0.

How to see your own identifiers

Windows does not show a single HWID, but you can see the main pieces in PowerShell:

• Get-CimInstance Win32_ComputerSystemProduct shows the system UUID.
• Get-PhysicalDisk shows each drive’s serial number.
• Get-NetAdapter shows network adapters and their MAC addresses.
• tpm.msc, run from the Windows and R box, shows whether a TPM is present.

None of these change anything. They only read what your hardware reports.

How anti-cheats use hardware IDs

To recognise returning players

If an account is banned for cheating, the anti-cheat can also record the hardware identifiers it was used on. A new account created on the same PC is then recognised and flagged, sometimes immediately, sometimes in a later ban wave.

To link accounts

The same identifiers show when several accounts are played on one machine, which helps games tie alt accounts and smurfs together.

To spot tampering

Identifiers that look wrong, such as missing serial numbers, values that change between sessions or combinations no real hardware produces, are themselves a signal that something is altering what the PC reports.

What a HWID ban means

A HWID ban is a ban on the machine. The account ban still happens, but on top of it the anti-cheat refuses the hardware, so making a fresh account on the same PC may not help.

Not every game issues hardware bans, and the ones that do decide which identifiers count. That is why the right next step depends on the game and its anti-cheat. Our support guide on HWID bans explains your options, and the support team can tell you the current approach for your title. Ask before you change anything.

Common misconceptions

“A new account gets around a HWID ban.” That is exactly what a hardware ban is built to stop. The new account is played on the same hardware, so it is recognised.

“My HWID is one number I can look up.” There is no single number. Each anti-cheat reads its own set of identifiers and combines them its own way.

“Changing my HWID is harmless.” Identifiers that look wrong or keep changing are a signal in their own right, as covered above. Ask support for your game before you change anything.

What changes a HWID

• Replacing parts changes the identifiers of the parts you replaced, and nothing else.
• Reinstalling Windows changes the identifiers Windows creates, not the hardware serial numbers.
• Updating drivers or firmware usually changes nothing.

Because an anti-cheat reads many identifiers at once, changing one or two parts rarely makes a PC look new to it.
