![](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.

Insanely frustrating, i'm really hoping microsoft fix this in the next update because this happening during finals season of my senior year of college is going to be the death of me.

Hi , Jacoui • I did the test here on my PC, apparently it's not a Chrome problem, but a Windows problem, but I managed to reduce the efficient mode request. Open the Control Panel, go to Hardware and Sound tab > Power Options > Select High Performance. Open microsoft edge go to settings > System and performance and disable all options. open Google chrome go to settings tab > system > disable all options. restart the computer open chrome again and access the extensions tab and disable all extensions and take the test. If possible, also perform a test by placing the sites in the assets tab in google chrome. Open google chrome select settings > performance > Keep this sites always active click Add.

More investigation: I turned on Memory Saver for Chrome https://support.google.com/chrome/answer/12929150?hl=en#zippy=%2Cturn-memory-saver-on-or-off%2Cturn-energy-saver-on-or-off I Restarted Chrome Reproduced same slow Meet meetings in Chrome, and same/ongoing meeting displays fine in Edge I uninstalled Windows 11 update KB5026375 [Windows button--> Settings --> Windows Update --> Update History .... scroll way way to the bottom... --> Uninstall Updates ] Restarted Windows 11 computer Now most recent update is showing as KB5026372 (successfully removed KB5026375) I re-opened all my 20+ tabs in Chrome I am now able to open and run Google Meet meetings inside Chrome browser with no dropped frames or truncated audio. It seems that removing KB5026375 update caused Google Meet meetings in Chrome browser to return to expected fast performance. I have paused updates for the max selectable 5 weeks and I will look for options how to avoid this kind of time waste in the future.

+1 It's necessary to make this annoying feature optional Chrome is feeling performance degradation while this mode is active. After reboot that mode will be inactive for some time and thus no performance issues

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

1. Open the Control Panel, go to Hardware and Sound tab > Power Options > Select High Performance.
2. Open microsoft edge go to settings > System and performance and disable all options.
3. open Google chrome go to settings tab > system > disable all options.
4. restart the computer open chrome again and access the extensions tab and disable all extensions and take the test.
5. If possible, also perform a test by placing the sites in the assets tab in google chrome.
- Open google chrome select settings > performance > Keep this sites always active click Add.

More investigation:

I turned on Memory Saver for Chrome

https://support.google.com/chrome/answer/12929150?hl=en#zippy=%2Cturn-memory-saver-on-or-off%2Cturn-energy-saver-on-or-off I Restarted Chrome Reproduced same slow Meet meetings in Chrome, and same/ongoing meeting displays fine in Edge

I uninstalled Windows 11 update KB5026375

[Windows button--> Settings --> Windows Update --> Update History .... scroll way way to the bottom... --> Uninstall Updates ]

Restarted Windows 11 computer

Now most recent update is showing as KB5026372 (successfully removed KB5026375)

I re-opened all my 20+ tabs in Chrome

I am now able to open and run Google Meet meetings inside Chrome browser with no dropped frames or truncated audio.

It seems that removing KB5026375 update caused Google Meet meetings in Chrome browser to return to expected fast performance.

I have paused updates for the max selectable 5 weeks and I will look for options how to avoid this kind of time waste in the future.
