Windows 11 disk usage 100% even with no apps open, very laggy
My disk usage hits 100% right after boot with no apps running. The system is extremely slow, even opening a folder takes a long time. Checked for bad sectors and disabled Superfetch, still the same.
Use the resource monitor to what app is doing all the disk IO. Replace your drive with an SSD if you haven't done so already.
Maybe it's doing windows updates. I no longer shut down my machine when I'm done using it so it's always ready to do work for ME when I sit in front of it.
