how long does your credit report reflect your bad credit

How long do credit files stay on my record? How long does your credit report reflect your bad credit?
7 years for bad credit, late payments, collections, charge off's. Lawsuits and judgments 10 years or until the statute of limitations runs out in the state. 3 years for inquiries. Diminished effect on my credit score takes place at 2 years out. Good or bad! If you have not used credit in 2 years you score will be gone. Must have used credit within the last 2 years.
