CMOS De-Animator is a service utility which allows you to invalidate the checksum of your system’s CMOS memory, resetting all settings to default and clearing any stored BIOS passwords (if any) upon re-boot. The main advantage of my utility is, that it can work under every Windows operating system, and no administrator privileges should be normally required! The utility has no GUI – only a confirmation message to begin or exit, error handling messages and a success dialog box upon successful operation. The utility is very portable, no installation required.

Note: In some cases, the utility may show “Operation completed!” without actually doing anything to the CMOS. In that case, executing the application and confirming the clearing process with one-time activated administrator privileges will do the trick. The next time you run the application, you will not need them. This is a driver-related issue.

The 32-bit version of this utility seems to provoke most false alarms on some antivirus programs; check the “Before you download” article for more information.
