What is lockapp.exe?

LockApp.exe is part of Windows and is the default Lock Screen app. It is responsible for the background immediately after switching on the PC.

Some of its graphic user interface elements include the background image, date and time, quick notifications, the power control switch to shut down or restart, some preferences set by the user to show on the lock screen, and network internet access status.

So, its process is what generates and controls the Lock Screen. Furthermore, the program doesn’t do more to the system and mostly doesn’t cause any issues with its performance.

Sadly, some users reported high CPU and RAM usage by the lockapp.exe and some other lockApp.exe system errors. This can happen for many several reasons depending on the circumstances.
