Disk at 100% on Windows 10

[soybean]

We can only see the top 4 items of your Task Manager panel.  And, it shows significant CPU usage in those 4 items, none of which are a game.  Do you know how much of CPU resource the game actually uses?

I am showing the Disk Usage Not the CPU I was just saying that yes the cpu usage is high but thaat there was a reason for that and has nothing to do with the disk issue

It's probably trying to do a Win10 update.  There was a big one on Tuesday.
Go to Settings---Update & security---Update status

According to the screencap it's also running an A/V scan...but as pointed out...we can only see 4 items...it could be a number of things.

This started about three weeks ago not just Tuesday

That image is not about he space used on the disk drive.
It is a report about what the disk drive hardware does.
The 97 % means the report is a near complete report. It has nothing to do with smooth  performance of the system.

Like if somebody says your car looks very clean. That does not mean the car is good. It only means  a worker made an effort to clean the car.  In fact, a car with a bad motor  can be very clean.

So the title of this  post is misleading.
Disk at 100% on Windows 10
...really means:
Windows 10 is  intently watching your disk drive.

Which coup imply that more work could be done if Windows stop looking at the drive interface activity and go do something more productive.

There is nothing wrong with the topic title. The problem is quite fully explained even in their initial post.

The 97 % means the report is a near complete report. It has nothing to do with smooth  performance of the system.

97% means that the Disk is pretty furiously writing or reading data to or from the disk (likely the former), and using up approximately that amount of the disks total reported performance capability. This usually does affect the smooth performance of the system because it results in all other I/O requests having excessive wait times. It's exacerbated somewhat because the Telemetry Runner Process has high I/O priority, for whatever reason. I've never seen 100% disk usage on any system not correlate with decreased performance, myself.

Reducing the Amount of Telemetry information that is tracked could help alleviate the problem:


Settings->Privacy and Security, on the left, click "Feedback and Diagnostics".

On the right under "Diagnostics and usage data" you can change the setting to "Basic". This should help reduce the amount of information That Windows will track and report to Microsoft, and thus what it will need to save to disk while it prepares it's report to the mothership about how you use your computer.

Alternatively, The Telemetry capabilities can be shut off entirely, this can be done by disabling the "Diagnostics Tracking Service" Service.
