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 don't have the extension, 128gig ram, 24 cores - and I can barely ruin 5 tabs without Chrome freezing constantly. FIX THIS BS MICROSOFT. Really missing my mac now...

    Someone else said it had to do with the McAfee WebAdvisor extension https://support.google.com/chrome/thread/209111340/chrome-has-been-slow-and-unstable-since-03-2023?hl=en

    I turned the extension off and my Chrome works fine now!

    I do not have that extension and am suffering the same issue.

    Hello Ivan,

    I have the same issues. They immediately began after updating my windows device to the latest update. Unfortunately, nothing will load in google chrome, including the settings and history tabs.

    Have a nice day!

    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!
