I recently updated to Windows 11 to avoid the notifications for Windows 10 updates, and since then my laptop has been crawling. It's been showing about 91% CPU usage and 97% memory in Task Manager, even when everything is idle and Windows Explorer isn't actually open. I'm really looking for help on how to fix this issue because it's making my laptop virtually unusable.

So, Windows Explorer is part of your system shell, which means it’s usually running in the background even if it looks closed. This is pretty normal behavior, as it uses resources for icons and menu entries. However, if it's consuming an unusual amount of CPU and RAM, that's definitely a problem. You might want to check if it’s running processes that are slowing down your laptop or even consider a system file check to see if there are any underlying issues.
If you’re still running on a pretty old laptop, it might struggle with the demands of Windows 11. It’s odd that you did fine on Windows 10 but hit a wall with 11. Maybe there are some background processes that weren't noticeable before, so keep an eye on what's running in Task Manager.
Just to clarify, was that 'kmb' actually supposed to be 'GB'? It seems like a typo, but that could explain a lot!
How much RAM does your laptop have? With only 8GB, it might be worth checking for corrupt system files. You can run the System File Checker by typing 'CMD' in the start bar, right-clicking it, and selecting 'Run as administrator'. Then enter 'sfc /scannow'. After that, do 'DISM /Online /Cleanup-Image /RestoreHealth' to fix any problems. Also, check for updates; they might help!
