How to disable efficiency mode in task manager? Windows efficiency mode is making apps like Google Chrome unusable.

![](https://learn-attachment.microsoft.com/api/attachments/e8c660f6-34c2-4550-a3a6-0c856ae2def3?platform=QnASince yesterday (28 March) Google chrome is unusable. Task manager on my windows desktop  says that efficiency mode is active for several but not all sub-processes of google chrome and I believe that is the reason for the drop in performance.

I am able to disable efficiency mode for each individual sub-process, but *it returns a few minutes later. I cannot permanently disable it.*Simple actions such as changing a tab or moving the window causes it to freeze for several minutes. 

  • I have no recent or current updates to install. Everything is up to date.- There are no other demanding processes / apps running on my pc- I have tried altering Chrome's performance and memory settings. Nothing changed.- This problem is the same with Edge and some other applications.- Efficiency mode is greyed out for the entire application. Only certain sub-processes of chrome are in efficiency mode.

The only difference between yesterday and today, is that efficiency mode is active non-stop.

I do not want efficiency mode running at all for google chrome as it is the main browser I use for work and school.

    I could solve this problem by disabling Help Improve by optimizing the content shown and brightness option in System->Display in Control panel.

    Attached the screenshot for reference when it was enabled.Image

    There has to be a registry switch somewhere to disable this bloody thing.

    @Jacoui,

    See my post

    Tl;dr - reverting/removing/uninstalling recent Windows Updates resolved this issue for me, and seems like is not related to Efficiency Mode.

    Tried all of these and it did not work.

    I could not do #5, since my chrome does not have the "performance" tab in the settings menu anymore. Not sure what that is about. I had that tab up until a few days ago.
