Diagnostic Strategy Service

It's done, I finally solved the problem.
So I followed this discussion thread which gave me a clue:
https://answers.microsoft.com/fr-fr/windows/forum/all/service-de-strat%c3%a9gie-de-diagnostic/caf72c32-5630-4571-8c28-5a0d7507da2a

In the task manager, I just had to go to "Services", then search for "DSP", right-click on it and stop the program.
I waited a bit, restarted it and now it doesn't rev up anymore, if I may say so.
So for now the problem is solved and it seems to hold.
I also took the opportunity to get rid of Malwarebytes.
In any case, I thank you for the solutions you provided, they were very helpful as it allowed me to clean up my computer.

Hello,
Sorry for replying a day late, but thank you for taking the time to respond to me.
Here are the three requested files:

Hoping this helps to clarify things.

Indeed, I messed up, my bad.
Here is the correct file:

Should I uninstall MBAM then?
Yet I have been using them together for years and it hasn't caused me any issues until now, but if needed, I'll get rid of it, no problem.
In the meantime, the problem persists; I’m reading solutions here and there, but none are conclusive.
To be continued.

Nothing extraordinary, but KIS + Malwarebytes might be too much.

1) Go to the Control Panel
then Programs and Features.
Uninstall:
CCleaner
CyberLink
NTI Backup
Malwarebytes

P.S.: CCleaner isn't really useful, even though it's recommended everywhere.
If you want to keep it, disable CCleaner's monitoring, as it starts up with Windows and slows it down with its constant cleanings. See: https://www.malekal.com/supprimer-ccleaner-demarrage-windows/
Also, remember to disable data sending in CCleaner's options. They send information to Avast! servers.

2) Disable/Remove from startup:
<ital>all Adobe programs/<ital>
See:

• how to remove a program from Windows startup
• Manage programs that start up with Windows 10

3)

Install "Real Temp" or "Coretemp" to Monitor the temperature of your computer.
Check how high the temperature of your computer rises during use. It should not exceed 60 degrees Celsius. If possible, attach a screenshot of the software to the message.

4) Finally, to go further, follow this tutorial: how to speed up Windows 10

See if this reduces the CPU usage.

Well, I spent two days following all sorts of tutorials, uninstalling this or that program or application, and still the same problem.
So for now, I’m giving up.
I’m just attaching two screenshots to highlight the issue I have:




There you go, I remain open to any responses that could provide me with a concrete solution, perhaps from people who have had the same issue.
