Did you ever forgot computer login password?

yes, and that i have reinstalled my OS

Chose one I would never forget.
Tends to help, though I would say I don't always do that practice due to how passwords need to be longer to be well...effective.

I log in with my windows live email and password, so nope!

My computer login password is the only password I don't forget.

I do usually forget my password everytime, usually when i forgot some website i have never used before and if i wrote it incorrectly. These are the only thing i knew so far.

This also happens when i reinstall my computer.

Not to my computer, but I've forgotten other passwords.
