Since Windows 11 24H2 update everything runs slow and takes longer to load

Ever since this update, my system takes a long time before it's fully up to speed. I'm talking 10 minutes or more. Even the opening screen where I enter my PIN takes longer to come up. After entering the pin, it takes a while for the app icons to show on the desktop and even then the taskbar arrives later. I can't get Outlook or Chrome to launch right away. It can take minutes for them to load and be responsive.

Even after the system is functioning more normally, it is still slower than before the update. Emails take a few seconds longer to open up. Files take longer to open. Chrome tabs take longer to show.

I've checked Task Manager. My CPU is at less than 10% and my RAM at 59% with apps open. Hard disk doesn't show a lot of activity. I've looked at processes and don't see anything that's consuming a lot of resources. Nothing obvious is showing up. I've made sure to turn off a lot of apps at start up that were unnecessary.

I've also turned off sys.main. Before that, everything was even slower and more annoying than what I have already described. Two other annoying things I've discovered. Microsoft turned off Malwarebytes and turned on Defender anti-virus without my permission. It also turned on Edge. None of these things should have been activated without asking my permission. The update should keep every app the way it was either turned on or off.

24H2 has changed something in my computer that affects all activity and load times. It is not hardware related.

I have a fairly fast cpu, ram and SSD disk access speed. This is a gaming computer. It worked fast before the update. I've made a few adjustments to speed things up but those were not necessary before 24H2.

I do enjoy reading the replies...they will never just admit that their software is ****. Which is the reason for issues 90% of the time

    Hi Peter,

    ALEX, thank you for your EM. Sir, frankly I DO NOT NOT to write any further comments on this DIRTY 2h24 Issue.

    I am PIKG DISGUESTED with Microsoft and its ENTIRE DILEMMA they caused all over the WORLD with that

    UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Frankly, I HATE HATE MICROSOFT PERSONALLY and want nothing

    more to do with it. I have now Mac Intosch and now it's peace on earth! GLORIDA IN EXCELIS DEI !!!!!!!!!

    Finished. OVER AND OUT TRANSMISSIKON CONCLUDED!!!!!

    I'm afraid Microsoft is not the only one to blame for the problems mentioned so far.

    I have spent a lot of time analyzing this problem over the last few days and also stumbled across this point yesterday.

    Windows 11 - Unerträgliche Ressourcenverschwendung - groteske RAM Reservierungen

    As you can see in the first video of this post, an older Edge browser consumes only a few resources for a given workload/test. In the second section of the first video and in the second video, you can see how many resources a current Chrome and Edge need for the same simple test. And in the third video, you can see the effect when CFG comes into play. 😔

    By the way, I did the tests mentioned above on a Windows 10 22H2, so the system is not quite as badly utilized as on a W11 24H2, where the whole problem is much more blatant. 😭 (See the other posts by me further up in this article.)

    Best Regards from Germany

    Hi Don,

    I have also had the same problem with my W11 24H2 workstation for months. 😞

    I have already tried various things, but the only thing that helps to a limited extent is to switch off the CFG (Control Flow Guard).

    I have also noticed that I have massive performance problems with all Chromium-based browsers, for example, but not with FireFox.

    My guess is that something is going wrong in the memory management, because both CFG and the Chromium-based browsers reserve a lot of “virtual memory” for themselves.

    The CPU of my workstation delivers a total of ~ 44 GHz and can access 128 GB RAM and yet I have not been able to work properly with this hardware for months. 😭

    Best Regards from Germany
