![](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.

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!

I'm having this same issue!! I'm on a desktop as well so I have no reason to have an efficiency mode, unless that efficiency mode was only active while I was tabbed out. My running theory for why this is happening and why its only happening to chrome is because microsoft is trying to turn people away from chrome and towards edge. Which is really not a very good look for the company. I don't know why we aren't able to just turn off efficiency mode on the main google chrome box in task manager instead of having to turn it off on every sub-process. Ridiculous. There better be a fix for this soon because this is unacceptable.

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!

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