I read through all the comments here. Looks like it has to do with a Windows update. I noticed the sluggishness, while I was working with a PDF program, Teams, ToDo, Google Chrome, and a few explorer windows open. I typically have this much or more open, so it was odd that it couldn't handle it. Then my browser crashed due to insufficient memory. I checked the task manager and saw that the culprit was Feeds, just like all of you guys, running nearly 100% of available memory and disk space. Fortunately I was able to end the program with Task Manager. After reading through these comments, I also disabled "News and Interests" on my taskbar. Not sure which one did it, or if this condition is permanent, but right now my laptop is back to normal. It shows that my Feeds is suspended to improve system performance, but I'm not sure how that happened. I have not tried manually downloading the latest Windows Update file. Has anybody had lasting success with this?

My system specs:
Dell G7 7700
Intel Core i7-10750H 2.6 GHz
16 GB Ram
64 Bit
Windows 10
NVIDIA GeForce RTX 2070
Thanks for everybody who shared their experience with this, and I hope mine helps somebody too.
