Diagnostic service runs in the Windows OS to detect and troubleshoot problems with the Windows components. This service is required to run the Diagnostics utility in Windows and it is a background service which means it is automatically started when you boot your system and keep running as long as the system is on. If this service is consuming an abnormally high amount of CPU and RAM then this will make the overall functioning of the Windows slow to respond to other processes and the user faces a lagging problem.

This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10 operating system (Home, Professional, Enterprise, Education) from all supported hardware manufactures, like Dell, HP, Acer, Asus, Toshiba, Lenovo, and Samsung.

I’ve tried everything, deleting the file, updating drivers, just disabling the program complete resetting my pc, updating bios, everything I am able to do in my power to fix it. I can’t get it to stop taking so much of my cpu power, I can’t even use my pc to browse the internet let alone use it for what I bought it for which was play games, I am at a loss on what to do, I’m about ready to buy a new pc.

Hi,
Tried, but could not delete %WinDir%\System32\sru SRUDB.dat file since it was in use by "stopped", or "stopping", or "disabled" Diag. Policy Service. (These are all status that I tried to perform the delete under. How do we get around this?
