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

    I’m having the same issues. My computer is pretty much unusable, even moving the mouse is lagging across the screen. I did the wi does repair, turned off all background processes and trimmed down my start up app and nothing has helped.

    Since this thread was initiated, I have been diligently checking it in hopes of finding a solution to the multitude of issues discussed. It is perplexing that Microsoft has not acknowledged or addressed the problem, nor have they even admitted that there is an issue at hand. The silence from Microsoft without a single word of acknowledgment is truly baffling.

    I recall your earlier comment indicating an intention to contact Microsoft officially, which I hoped would lead to some resolution. However, Microsoft has marked a comment in this thread as a solution without thoroughly investigating the users' concerns. This gives the impression that Microsoft either does not comprehend the problem or is deliberately ignoring it.

    The current situation has significantly impacted my ability to use my computer effectively, and consequently, my work performance has suffered. Despite owning a brand-new, high-specification computer, it now feels unusable.

    This issue demands serious action from the user community, but I am uncertain about the appropriate steps to take. I am really thinking of stopping using Microsoft windows and starting using any other OS.

    I had one computer that wasn't usable at all and 3 running slow, expecting updates that might address issues with the 24H2 I originally did a fresh install and still no good. Now all of a sudden one day after a few updates there all running fine even the one that wasn't usable at all, it's back up and running just a fast as ever as if nothing ever happened. Was about ready to buy a new PC. Happy ending. :-)

    And what about if I already installed 24H2?

    Should I install the on-site upgrade over my installation?

    Hi, I made some tests, too, and I found that an on-site upgrade to 24h2 works fine. The thing is, you should have a lot of patience to run the media from the slow Windows OS.
