What is LockApp.exe?

LockApp.exe is part of the Windows 10 operating system and is responsible for displaying the lock screen. Specifically, LockApp.exe displays a lock screen overlay that appears before logging on to the computer. This screen shows the background image, time, date, and other items you have selected showing on the lock screen such as weather forecasts or new email information.

The LockApp.exe process displays this screen and the information on it.

Most of the time, this process does not perform anything, it only works when you are at the lock screen. It appears when you log on or lock your computer by clicking the Lock option in the Start menu or pressing Windows + L. It will hang up and stop working after you log on.

Here is a screenshot of the LockApp.exe process running on the Process tab in Task Manager using the program startup trick on the Windows logon screen. Normally, you will not see it in the process list at the Process tab, although some system tools may tell the user that LockApp.exe is running on the PC.

This process uses a lot of system resources?

Lock app does not use a lot of system resources. If the system notification tool has been running for a while, this means your computer is locked and “awakened” for a long time.

With the program lock on the lock screen, you will see the Lock app only use 10-12 MB of memory and very low CPU usage. After logging in, LockApp.exe will automatically shut down and use only 48K of memory. You will see this information in the Details tab of Task Manager.
