Which PsLoggedOn parameter prevents showing logon times while displaying user details?

The parameter that prevents showing logon times while displaying user details in the PsLoggedOn tool is the "-x" option. When you utilize this parameter, the output will include user details but omit the specific logon times, allowing for a more concise presentation of logged-on users without the additional timestamp information.

The other parameters serve different purposes: "-l" is used to list the user accounts and their logon times, providing a detailed snapshot of usage; "-n" allows for a more limited view, focusing on network logons; and "-a" displays all sessions, including those that are not currently active. Each of these options modifies how the information is presented, but only the "-x" parameter specifically avoids displaying logon time.
