Notebook Operating System and Recovery

My laptop was working fine with Windows 10 (which came preinstalled).  When Microsoft pushed out the Windows 11 updates, it took forever to update.  Since then, it's been running with Disk Usage at 100% according to the Task Manager.  It's very slow.  I tried to find specific tasks that were hogging the system, but the tasks running don't add up to anywhere near 100%.  I went through a dozen articles on the Internet on how to fix the 100% disk usage problem and turned off whatever services I could and tried whatever was suggested.  I even booted into safe mode to see if there was still an issue when there weren't as many drivers and applications running.  It's still slow and still reads 100% disk usage.  I'm wondering what to try next.  Is there anything I may have overlooked in trying to get Windows 11 to work properly?  Should I wipe everything and try to reinstall Windows 10?  Should I just put Linux on the system and give up on getting Windows to work properly with the drive?  I'd appreciate some suggestions.  Not sure what to try next.
