![](https://learn-attachment.microsoft.com/api/attachments/e8c660f6-34c2-4550-a3a6-0c856ae2def3?platform=QnA Since 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.

Can confirm that efficiency mode bug happens on Edge too , not just Chrome in my case.... although I only feel the lagginess when using resource-intensive websites Only Brave Browser doesn't get cursed with Efficiency Mode bug... I wonder why. Please fix this bug Microsoft! Some context: Chrome MS Edge Brave Browser And yes, I have tried fixes mentioned by the original poster but no luck.... that leaf icon returns after few seconds of disabling the 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.

Opera is the only browser I can use now. Everything else has become unusable

In my case, Chrome Edge and Firefox all become unusable. Only Opera survive~

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