Hi. My PC have two user accounts: Admin (Administration) and Guest (Standard). i sat time restrictions for Guest account. then, for testing, i restarted my pc and tried to log on with Guest account at certain time. but it showed me this error: "Your account has time restrictions that prevent you from logging on at this time. Please try again later" What is the reason? What should i do to solve it? i should add that my Guest account is a Standard account.
