If you want to clear CMOS memory from Windows, which resets BIOS settings to default, you can use CMOS De-Animator utility for that. CMOS De-Animator allow you to invalidate checksum’s of your system’s CMOS memory, resets all settings to default and clears any stored BIOS passwords if any upon reboot.
This utility doesn’t a have graphical user interface. Run the utility, click ‘OK’ for the confirmation message to clear CMOS memory.
CMOS De-Animator is freeware and portable, runs on all Windows operating systems, no administrator privileges required.

I tried to download the 32-bit version of CMOS De-Animator, but Avira denied access to the file. I got this message:
“Virus or unwanted program ‘DR/Delphi.Gen [dropper]’
detected in file ‘C:De-CMOS.exe.”

It’s upto you to decide
But does this works on all BIOS like AMI, Award etc ?
Yes it does work on all BIOSes. Altough on some systems, the utility might need to be run under one-time administrator privileges, and then it will work for all users system-wide. Unfortunately this is a driver related issue.
