Introduction to LockApp.exe
To begin with, what is LockApp.exe? It is common to see the process named LockApp.exe running on your PC when you open Task Manager. LockApp.exe is a component of the Windows system (Windows 10/8/7/XP), which is used to display the lock screen.
The LockApp.exe file is located in a subfolder of C:\Windows (e.g. C:\Windows\SystemApps\Microsoft.LockApp_cw5n1h2txyewy). And the process is used to show you a beautiful background image, date, time and other “quick status” items that you have set to show on your lock screen.
Actually, the LockApp.exe process doesn’t do any work most of the time. The only thing it needs to do is to show what you want to see on the lock screen. Therefore, it only works no matter when you sign in to your PC or press the Win + L keys to lock your computer. And after you have signed into your computer, the LockApp.exe process suspends itself and stops working automatically.
What’s more, you can only get the screenshot of the LockApp.exe process running on the Processes tab according to a geeky trick to run programs on the Windows login screen. Some system tools may tell you that the LockApp.exe process is already running on your computer, but you usually don't see it at all on this list.
Does LockApp.exe Use Much System Resources?
In fact, the LockApp.exe process doesn’t consume much system resources and it only uses about 10 to 12 MB of your system memory when it is fully functional. And when the process suspends, it only consumes 48 K worth of memory. You can get detailed information on the Details tab of the Task Manager.
So if a system tool informs you that the LockApp.exe process has been running for a long time, then this means that your computer was locked and awake for a long time.
The LockApp.exe process is designed to be lightweight and tiny. If this process does use a lot of CPU, memory, or other resources, then you have encountered a major error in Windows.
