Why did Windows 11 suddenly become slow?

I received notification from Windows a few months ago and upgraded to Windows 11. It was fast and smooth in the beginning, but in the last two-three weeks, it has become significantly slow. It annoys me a lot, simply file browsing has been painful. It takes forever to open a web site on Chrome. This never was the case before, my laptop used to be really fast. I am suspicious that this is because of recent Windows 11 updates. I just want to go back Windows 10 and have my laptop speed back.

Another issue in Windows 11 that annoys me a lot is the tabs in taskbar. They frequently disappear. For instance, if I have 5 apps open, suddenly all the icons in taskbar disappear and I have to restart file explorer to fix it.

How do I fix all these permanently, or go back to Windows 10?

Window 10 is fast.

If only I had known about the 10 day limit on downgrading. Now, I have a $600 paper weight. This laptop is so slow that I can see individual components rendering on virtually every app, browser or otherwise. Honestly, it reminds me of 300 baud modem days. I think I need to install Linux to get my work done.

I was experiencing this very slow issue, slow to access hard drive, slow to access memory, looks like it thinks it only has one single processor and it would BSOD at times, particular using Google Chrome. After reading all of these articles on this issue. I updated my Nvidia GeForce GTX 1560 video driver from v451.67 to v526.47, reboot. I then updated my desktop to Windows 11, version 22H2 and all is ok again. This laptop is an Acer Nitro 5 with 24GB of RAM

The best option is to downgrade to Windows 10. I gave Windows 11 another chance but it just gets worse. I am using HP ZBOOK with Core i7 8th gen, 16 GB RAM 0.5 TB SSD. I never had performance issues with Windows 10. If anybody else is having problem from my experience going back to 10 is the best option.

I kept cleaning temporary files, turned of the features that I do not use, tried not to open a lot of application, but nothing worked. My laptop was always up to date. That's another issue, the updates in Windows 11 is overwhelming. I understand that it is relatively new and the developers keep fixing bugs and increase security. I am just not ready for it yet. Maybe in the future when Windows 11 gets more stable, fast and reliable, I will give it another try.

ya I just noticed this too; is it temporarily to collect emergent cyberthreats maneuvering pointers and data to avoid detection by av?
