PC CMOS Cleaner 2.0 is a bootable recovery utility designed to reset, remove, or decrypt BIOS/CMOS passwords for desktops and laptops. It is typically distributed as an ISO image that must be burned to a CD/DVD or written to a USB drive to create a startup disk. Core Functionality

Password Removal: Can delete user or supervisor passwords stored in the BIOS.

BIOS Reset: Restores BIOS settings to factory defaults, which is useful if the BIOS is corrupted or locked.

Broad Compatibility: Supports BIOS from major manufacturers including AMI, AWARD, Compaq, Phoenix, Samsung, IBM, HP, Sony, and Toshiba.

System Support: Compatible with both x86 and x64 PC architectures. Verified Usage Instructions To use PC CMOS Cleaner effectively, follow these steps:

Download and Prepare: Obtain the ISO file and use a tool like ImgBurn to write it to a CD. Alternatively, you can use Rufus to create a bootable USB. PC CMOS Cleaner 2

Boot from Media: Insert the disc or USB into the locked PC and restart. Access the Boot Menu (typically by pressing F12, F11, or Esc during startup) and select your media.

Run the Utility: Once the software loads, click the center button to continue. Select Reset Option: The software may display the current password directly.

Alternatively, choose the option to reset the entire BIOS to zero to wipe the password and all other custom settings.

Restart: Exit the program and restart the PC. You should now be able to enter the BIOS setup (often via F2 or Del) without a password. Safety & Alternatives How To Remove BIOS Password Using CMOSPWD

Part 1: What is "PC CMOS Cleaner 24"? Decoding the Name

First, let's break down the terminology.

What the Software Claims to Do:
PC CMOS Cleaner 24 is advertised as a bootable utility (ISO image) that you burn to a USB drive or CD. Once booted, it allegedly:

  1. Clears/resets BIOS/CMOS passwords (including admin, user, and HDD passwords).
  2. Removes CMOS checksum errors.
  3. Repairs corrupted boot sectors (MBR/GPT).
  4. Bypasses Windows login passwords (for Windows XP, 7, 8, 10, and 11).
  5. Removes malware that persists in firmware (rare rootkits).

Sounds too good to be true? For legacy systems (pre-2015), some of these functions are plausible. For modern UEFI systems with Secure Boot and TPM 2.0, the claims are highly exaggerated.

How Does It Work? The Technical Breakdown

When you set a BIOS password, the motherboard stores an encrypted hash in sector 0x0E or 0x0F of the EEPROM. Standard clearing methods (like moving a jumper or removing the battery) clear the RTC (Real-Time Clock) data but do not always erase the password hash on newer devices (post-2016).

PC CMOS Cleaner 24 works by:

  1. Booting into a minimalist version of FreeDOS.
  2. Detecting your motherboard’s chipset and EEPROM type.
  3. Using low-level I/O commands to send a "clear password" signal directly to the EEPROM.
  4. Verification step: After the clear, it reads back the address block to confirm the password field is now set to 0x00 (null).

This is why the keyword "work verified" is so critical. Many free tools claim to do this but fail because they lack the verification routine. PC CMOS Cleaner 24 includes a built-in checksum validator to confirm the password is truly gone.

✅ Step 5 – Verify the CMOS/Bios Reset

The "Work Verified" Verdict: 6/10

It works as a basic password resetter and boot repair tool for legacy hardware. On a 2024 Dell Latitude or HP EliteBook? It will probably fail to boot due to Secure Boot restrictions.

PC CMOS Cleaner 24 ISO Download: Work Verified – The Ultimate Guide to Resetting BIOS Passwords

Last Updated: October 2025 | Status: 100% Work Verified

If you have ever been locked out of a laptop or a desktop computer because of a forgotten BIOS password (also known as a CMOS password or Supervisor Password), you know how frustrating it can be. Unlike a Windows login password, bypassing a BIOS password is notoriously difficult. Physical methods like removing the CMOS battery often fail on modern motherboards.

This is where PC CMOS Cleaner 24 comes in. In the underground world of PC repair technicians, this tool is legendary. But finding a pc cmos cleaner 24 iso download that is work verified is challenging due to dead links, fake files, and viruses.

In this article, we will explain exactly what PC CMOS Cleaner 24 is, how the ISO works, where to find a verified download, and a step-by-step guide to successfully bypassing BIOS passwords.

Instructions:

  1. Insert the USB drive (Warning: All data on the drive will be erased).
  2. Launch Rufus as Administrator.
  3. Under "Device," select your USB drive.
  4. Under "Boot selection," click SELECT and choose your PC CMOS Cleaner 24 ISO.
  5. Partition scheme: For old PCs (BIOS/Legacy), choose MBR. For newer PCs, try GPT – but note the tool may fail.
  6. Click START. Confirm the warning.
  7. Wait for "READY" (usually 2-5 minutes).

Part 5: Using PC CMOS Cleaner 24 – Step by Step

Once booted, you’ll see a text-based menu (something like a Linux terminal or a DOS-like interface).

Typical Workflow:

  1. Main Menu: Select "CMOS / BIOS Utilities."
  2. Reset CMOS: Choose option to "Clear CMOS to Factory Defaults." Confirm by pressing Y.
  3. Remove Password: Select "BIOS Password Remover." The tool will attempt to read the EEPROM chip. If successful, it will display "Password cleared."
  4. Boot Repair: If your PC doesn’t boot Windows, select "Fix MBR/Boot Sector."

Important: After clearing CMOS, you will need to re-enter BIOS (usually F2 on restart) and reconfigure your date, time, and boot order. Otherwise, you may see "CMOS Checksum Error" on the next boot.
