How to Automatically Close Inactive Apps in Windows 11 to Save RAM

If you leave multiple heavy applications running in the background—such as web browsers with dozens of tabs, video editors, or game launchers—Windows 11 can quickly run out of available Random Access Memory (RAM). When RAM is depleted, the system is forced to use the hard drive as virtual memory, resulting in severe lag, stuttering, and unresponsiveness. While you can manually open Task Manager to kill processes, it is far better to configure the operating system to automatically throttle or close inactive applications to preserve system resources.

Method 1: Utilizing Windows 11 Efficiency Mode

Windows 11 introduced a native feature called “Efficiency Mode” specifically designed to combat resource hogging. While it doesn’t force-close the app entirely, it severely limits the CPU and RAM allocation for apps that are running silently in the background, suspending their active processes until you bring their window back to the front.

1. Right-click on the Start button in the taskbar and select Task Manager.
2. Click the Processes tab (the icon with four squares) on the left-hand sidebar.
3. Identify an application that is consuming a large amount of memory but does not need to run actively in the background.
4. Right-click the application’s name.
5. Select Efficiency mode from the context menu.
6. A warning prompt will appear explaining that this may cause instability in certain apps. Click Turn on Efficiency mode to confirm.

A small green leaf icon will appear next to the app’s status, indicating that Windows is now actively suppressing its background resource usage.

Method 2: Configuring Background App Permissions

If you have applications installed from the Microsoft Store (such as Xbox, Spotify, or various utilities), Windows 11 allows them to run in the background by default to receive notifications and updates. You can strictly revoke this permission, preventing them from consuming any RAM when their main window is closed.

1. Open the Settings app (Windows Key + I).
2. Navigate to Apps on the left-hand sidebar.
3. Click on Installed apps.
4. Scroll down to find the specific app you want to restrict.
5. Click the Three dots (…) next to the app’s name and select Advanced options.
6. Scroll down to the Background apps permissions section.
7. Click the dropdown menu under “Let this app run in background” and change it from “Power optimized” to Never.

The moment you close that application’s window, its processes will immediately terminate, instantly freeing up the associated RAM.

Method 3: Aggressive Automation via Task Scheduler

For advanced users who want to forcibly terminate a specific program (like a game launcher that stubbornly stays open in the system tray) after a certain period of inactivity, you can create a custom automated task.

1. Click Start, type Task Scheduler, and press Enter.
2. In the right-hand “Actions” pane, click Create Task….
3. In the General tab, name the task (e.g., “Kill Epic Games Launcher”).
4. Go to the Triggers tab, click New, and select On idle from the “Begin the task” dropdown. Click OK.
5. Go to the Actions tab, click New. Ensure “Start a program” is selected. In the “Program/script” box, type taskkill. In the “Add arguments” box, type /F /IM EpicGamesLauncher.exe (replace with your target executable). Click OK.
6. Go to the Conditions tab, check the box for Start the task only if the computer is idle for: and select a timeframe (e.g., 30 minutes).
7. Click OK to save.

Windows will now automatically run the kill command to silently force-close that specific application whenever you step away from the computer, guaranteeing a fresh pool of RAM when you return.
