- Efficiency mode limits priority and applies EcoQoS to save resources without killing processes.
- It is enabled from Task Manager in Windows 11 22H2 and not all processes support it.
- There is no persistent native setting per app for Win32; in UWP there are background options.
- The new display and sleep settings are independent of efficiency mode.
The call efficiency mode in Windows 11 It is a function that limits the CPU and energy consumption of specific processes so that what really matters to you runs smoothly. This feature was born in the Microsoft ecosystem and has been gaining prominence with the great 22H2 update, where the venerable Task Manager has also been given a facelift.
Visually, when a process is in efficiency mode, Task Manager marks it with a green leaf icon. That little indicator is key to identifying at a glance what is being “capped” to save, so you can quickly reverse or maintain the decision.
A Task Manager finally up to par in Windows 11 22H2
With the 22H2 update, Microsoft has taken a step forward with a revamped Task Manager. Tabs have been relocated, Fluent UI has been adopted, and a design consistent with the rest of the system has been adopted., moving away from that legacy aesthetic that it had been dragging since Windows 8. It is not the only corner of the system that had remained almost frozen (some Windows 95 icons survived even until Windows 10), but here the jump is especially noticeable.
In addition to the facelift, practical features are also coming. The star of the show is the efficiency mode, integrated into the Processes view and accessible with a couple of clicks. The combination of a clearer interface with useful controls like this makes managing performance easier and, above all, less risky. than the classic “End Task” solution.
How to activate and use efficiency mode step by step
Using efficiency mode in Windows 11 is done from the Task ManagerYou can open it with Ctrl + Shift + Esc, Ctrl + Alt + Del, or by searching for it from the taskbar. Once inside, go to the Processes tab to see everything that is running. at that moment.
To identify what's hogging resources, click the CPU, Memory, Disk, or Network column headers. By sorting from largest to smallest, you'll quickly find what's putting the most strain on your computer.This view helps you decide which processes are worth acting on.
Select a process and, if it's supported, you'll see the Efficiency Mode button (top right) become grayed out. Click and confirm in the pop-up window to activate it.If the button remains off, that process either doesn't support the function or the system considers it a priority for stability.
Reverting to Efficiency Mode in Windows 11 is just as simple. Locate the process marked with the green leaf, right-click, and select Efficiency Mode again. The mode acts like a switch: you turn it on or off per process depending on what you need in each session.
Which processes should be limited and which ones are best left untouched?
There are programs that, even when “closed,” maintain resident processes consuming CPU, memory, disk or network. Auxiliary services, updaters, background utilities, or apps that synchronize data They are clear candidates for efficiency mode when they do not contribute anything at that precise moment.
However, not everything is valid. There are critical system processes and components, such as BitLocker, which Windows protects and for which the efficiency mode button is not available. Forcing limitations on essential elements can result in blockages or malfunctions., which is why the system itself sets up barriers. Use it wisely: on secondary apps or program processes you don't care about right now.
When it comes to browsers, the situation can be peculiar. Some users have observed that the entire browser seems to be in efficiency mode and that Disabling it from Task Manager does not always work or re-enable it.In these cases, it's a good idea to review the browser's internal settings (for example, in Chrome, the Performance section) and see if there are any interfering policies or extensions.
Persistence and Limits: Can Windows 11 Efficiency Mode be set for each app?
One of the most frequently asked questions is whether there is a permanent setting to always have a desktop app (Win32) run in efficiency mode, or just the opposite: never activate it. Currently, the setting you apply from Task Manager is not persistent between sessions.; When you close the program or restart it, the settings are lost and you'll have to repeat them if you need them again.
For UWP apps from the Store, there are advanced per-app options available under Settings > Apps > Installed Apps > … > Advanced, targeting background behavior. However, for many desktop applications there is no equivalent native switch that perpetually forces efficiency mode., and that is a limitation that several users have pointed out.
Another common complaint is that Windows automatically activates efficiency mode for certain processes, even when you have a “prompt before activating” setting enabled in Task Manager. If you see that it is applied without confirmation, it may be due to the internal logic of the system or priority criteria. that Windows considers to preserve overall responsiveness.
As an alternative, some users suggest third-party utilities (e.g., Process Lasso) to automate rules by process. The idea of relying on external software for something so basic may not appeal, but today it is the most flexible way to orchestrate persistent policies. when the system itself does not expose fine-grained control per application.
What efficiency mode is not: power shifts and system sleep
It's best not to mix apples and oranges. Windows 11 has also adjusted default display and sleep settings to reduce power consumption when the device is inactive, but That's not Task Manager's efficiency mode.They are different measures that share a common objective (savings and performance), but operate on different levels.
On devices with Modern Standby, the new defaults shorten the time before the screen turns off and goes to sleep. For example, with battery, the screen goes from turning off after 4 minutes to doing so after 3; when plugged in, from 10 to 5 minutes. Sleep mode also brings the device's wake-up time forward: on battery, from 4 to 3 minutes; plugged in, from 10 to 5 minutes.
On machines with “classic” S3 suspension, the default setting has also been made more aggressive to save: With battery, the screen turns off after 3 minutes (previously 5) and plugged in after 5 (previously 10). For sleep mode, the battery life goes from 15 minutes to 10 minutes, and plugged in from 30 minutes to 15 minutes. These changes help the device consume less power when you're not using it.
If you want to review or change these display and sleep policies, go to Start > Settings > System > Power & > Display, sleep & hibernation timeouts. Check how to fix it. Adjusting these times does not disable or control the process efficiency mode., but it can improve autonomy and temperature in real use.
When is it worth using efficiency mode in Windows 11?
Efficiency mode is ideal when you have secondary processes that you want to keep alive, but don't need them to run at full speed. Typical examples: synchronizers, background messaging clients, previewers, third-party indexers, or updates you don't need to finish right away. The CPU and power savings are noticeable without impacting your main activity.
It's also a useful tool if you're working with heavy software (editing, IDEs, virtual machines) and need to open a supporting app at the same time, which by default would tend to hog the CPU. By limiting your appetite, you prevent it from “stealing” rhythm from what really gives you productivity., especially on computers with modest multi-core CPUs or thin laptops that easily overheat.
On the other hand, it doesn't make sense to apply Efficiency mode in Windows 11 to processes you're currently dependent on (your game engine, a video export you need to finish right away, a critical compilation). Efficiency mode is not a turbo; it's a controlled brake. Use it as such.
Efficiency mode in Windows 11 is here to stay as an ally when it comes to taming greedy processes, and the new Task Manager makes it very handy. Remembering that it does not replace the system's energy policies, nor is it a magic button, but rather a surgical tool, you will be able to take advantage of it in your daily life.
