Disk 0 (C: D:) 100%?

So I started up my computer this morning and found that it was running extremely slow, much slower than usual. I decided to take a look at the performance tab of task manager and WHAM:

Now I'm no expert but I'm pretty sure that isn't a very good thing.
Next I took a look the resource monitor, however I don't really understand what any of its information means, I just assume the big numbers are a bad thing:

Lastly, I looked at my windows processes to see how much disk space the processes were taking up:

The only thing I found there that stood out to me was the Service Host: "Local Service(Net..." part (the one that shows 19.0MBs), it would occasionally go up to about 100MBs before slowly going down, then shooting back up.

I don't know what most of this means, I just posted as much information as I could, if I missed something important let me know, I just want to know how I can fix this

Did you let it run for a bit? it may be windows updates happening. Or windows updates are corrupted. I would check that first and see if it cleared up that way.

Next thing that can do it is a corrupt antivirus software, especially Windows Defender. What do you use?

You should check health of your seagate disk drive with hdtune.

Yeah I let it run for maybe 20-30 mins and it didn't change, I then restarted the computer and it went to 100% for about 15 mins, then went down to normal. So far its seems to be staying normal.

I use Windows Defender

Ok its possible defender was corrupt and needed to rebuild its database. I agree on checking the drive health as well, but its probably ok. Check your updates make sure they all installed.

Then reboot the PC, see if it does it again.
