Uses of LockApp.exe

The main function of LockApp.exe is to create the graphical user interface which overlays the lock screen. All the background images, date, time, and other notifications, and status that you see on the lock screen are created, maintained, and updated by this app.

The LockApp.exe is only executed when you are on your lock screen overlay, i.e, either when you are signing in to your system, or when you press WIN + L to go to the lock screen manually.

And, for the rest of the time, the process remains suspended.

Does LockApp.exe affect your system resources?

If your system is lagging and working slowly, then it isn’t probably the LockApp.exe that is bogging down your system, unless it has a bug. Usually, it consumes a negligible amount of memory.

It has been noticed that the LockApp.exe takes about 10-12 MB of memory when you are on your lock screen. As stated earlier, the LockApp.exe process is suspended after you have signed in and takes about 48 K worth of the memory in its suspended state. On the newer versions of windows, it does not consume any memory at all. Here is a screenshot of the LockApp.exe process from the Task Manager that shows its resource consumption.
