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.

    In fact, it disables the efficiency mode, task scheduler confirms it, but still have slowness issue in Chrome. The root cause must be somehere else unfortunatly.

    I don't believe this a Windows 11 Efficiency mode issue. We are seeing the same problem across our business using Windows 10 in Australia, Singapore and the Middle East. It doesn't seem to have reached our Europe offices yet. So far, the only fix I have found is to ask all our users to use Edge browser.

    Anyone else seeing the same thing?
