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 liked the idea of disabling windows defender. Though, I just had to upload a company required VPN and defender turned itself off. I am going to check that it is off and say company manages. It takes 15-20 minutes to get access to my computer. Frustrating and I do not have time! Unfortunately, on my associate's computer, like on mine, the upgrade accidently got uploaded when I had to do a restart. Really, with this many complaints, where is MICROSOFT?

    I had this issue and took a while to figure out that the problem was caused by the update to 24H2. After three days of research, I decided to roll back the version. Unfortunately, yesterday, I unintentionally updated this shi** **** again, and the problems came back.

    I tried several fixes, and the one that seems to have solved my issue was disabling Windows Defender. I used Defender Control 2.1 to do so, which set Defender to "managed by my organization" -probably an exploit to disable it completely. Now, my machine is almost back to how it was before, though I’m not 100% sure, as some things still feel a bit slow.

    Specs:

    • CPU: i7 14700KF
    • GPU: RTX 4070
    • RAM: 48GB DDR5 7200MT/s Corsair Dominator
    • Storage: 2TB NVMe SSD (Hiksemi) – 6.5K Read / 7K Write

    WOW! U need to do all that and back in the 90s you just turn on and all works well after updates. I cant believe Microsoft is literally forcing customers, especially the non computer savy ones to suffer through these issues. People that are tech savy can probably update drivers on their manufactuerers website, others will not know how to do so. I just cant believe Microsoft is literally making all our computers slow, unpleasant to use and unlike any other Windows I have ever used. SO MANY BACKGROUND PROCESSES. Microsoft I think has been hacked and doesnt want to tell the public and they scramble to make patches and bug fixes which actually make things worse as they have no clue whats going on themselves.

    I literally will never buy a Microsoft windows product ever again if this is how updates are going to be. LETS GO APPLE IOS! never had issues with their computers operating systems and updates like this. So sad to see Microsoft not be able to deliver a proper update that actually enhances my computer rather than negatively affects it or infects it. Is Bill Gates creating computer and real life viruses like those conspiracy theorists say?

    I can confirm that removing Windows Defender drastically improved file browsing experience in Windows 11 24H2, so yes - Defender services are real performance killer. Obviously Microsoft antivirus software can be called the biggest malware/spyware/unwanted software which is not that easy to remove and since Microsoft is not owner of my computers, looks like this is the case for regulatory bodies of EU, especially in the light of the new trade wars ...
