Check Your Device's HWID and Hardware Serial Numbers
Download the portable Windows 10/11 tool to view SMBIOS UUID, BIOS, motherboard, disk and RAM serials, CPU ProcessorId, MachineGuid and MAC addresses, or use the macOS and Linux commands below to read available device identifiers. The Windows tool also creates a composite SHA-256 HWID and exports text or JSON — no installer or identifier upload required.

A hardware ID is your device's fingerprint
A hardware ID (HWID) is a value derived from one or more device identifiers, such as a motherboard UUID, disk serial, network address or operating-system installation ID. Different software can calculate different HWIDs for the same machine.
HWIDs may appear as UUIDs, hashes, MAC addresses, serial numbers or vendor-specific strings. The online checker identifies likely formats and explains their structure; it cannot prove which device produced a value.
Four ways to work with HWIDs
Read hardware identifiers
Use the Windows utility for a local report, or run the documented commands on Windows, macOS and Linux to read individual identifiers.
Learn moreInvestigate a possible HWID ban
Answer eight questions to estimate whether a restriction behaves like a hardware, account or IP ban. The result is diagnostic, not an official verdict.
Learn moreValidate, parse and compare IDs
Paste an identifier to detect its likely format, inspect its structure or compare it with a local list in your browser.
Learn moreHow the Windows utility works
Download the Windows tool
Download the portable x64 executable for Windows 10 or 11. It runs without an installer; access to some identifiers still depends on Windows and the device firmware.
Read your hardware
The tool reads the identifiers that Windows and your firmware expose, then hashes the available stable values with SHA-256 into one composite HWID.
Review or export
Review the raw identifiers and composite hash, save a timestamped text report, or output JSON for scripts and support workflows.
Who uses HWIDs
Software licensing
Bind a licence to one machine so a serial can't be shared across unlimited devices.
Anti-cheat & HWID bans
Compare the behaviour of a restriction with common account, IP and hardware-ban patterns without claiming access to a game's internal records.
IT & fleet management
Associate inventory records with devices and detect when selected hardware identifiers change.
Support triage
Attach a consistent device identifier to logs or tickets so repeated reports can be associated with the same machine.
Frequently asked questions
What is a HWID?
A hardware ID is a value derived from one or more device or operating-system attributes. Software may use it to recognize a machine for licensing, device trust or support, but no HWID is guaranteed to be unique or permanent.
Is my HWID sensitive personal data?
A HWID can single out a device and may be personal data when linked to a person or account. The browser tools and Windows utility process identifiers locally unless you deliberately send a value to the validation API or share the output yourself.
Can I check a HWID someone sent me?
Yes. Paste it into the online checker to see its format, or use the List check tab to see if it is on your allowlist or blocklist.
What formats do you support?
UUIDs and GUIDs, MD5/SHA-1/SHA-256/SHA-512 hashes, MAC addresses, Windows product keys, Base64, hex strings, serial numbers and prefixed composite IDs.
What does the Windows EXE do?
The portable command-line tool reads identifiers exposed by Windows and your firmware, prints a composite SHA-256 hash, and writes a file only when you request an export. It does not upload the result.
How is the tool different from running commands myself?
The documented commands are best when you need one specific value. The Windows utility collects several available identifiers in one run, creates a composite hash, and can export text or JSON. PowerShell CIM commands are the modern choice on systems where wmic is unavailable.
Can someone track me using my HWID?
Installed software may read hardware identifiers when the operating system permits it. A normal web page cannot read motherboard or disk serials, but it can build a browser fingerprint from exposed signals. Treat persistent identifiers as personal data and share them only when necessary.
How do I reset my HWID for a software license?
You cannot directly reset a HWID — it is tied to your hardware. But most licensing systems provide self-service deactivation: release the old device through the vendor's portal, then reactivate on your new hardware. If you have changed hardware and lost access, contact the vendor's support.
