Cleaning to factory settings

[Miss Trust]

I am about to clean out my desk computer back to factory settings as I want that before getting rid of it.

I forgot my passcode and can't put the disc in without it.

Is there any way I can reset the passcode?

Thanks

This is done. Cory helped me. Thanks

Would you share it on how to do that?
