To reformat and reinstall is considered the "nuclear option" when it comes to dealing with Windows problems (or just cleaning up).

A scam claims your email account has been hacked, possibly even including a password you've used. Don't be fooled.

System Restore is allocated a certain amount of space on your hard disk. If that's excessive, you can use less space, but at the cost of fewer restore points.
