#Microsoft download manager use cpu driver
It exists solely to host operating system threads for the memory manager, cache manager, and other subsystems, as well as device driver threads. The System process is special because it doesn’t host an executable image like other processes. However, I could see by opening Process Explorer’s System Information dialog that the CPU spikes were significant: The first few times I noticed the problem, it resolved itself shortly after and I didn’t have a chance to troubleshoot. The icon opens a tooltip that reports the name of the process consuming the most CPU when you move the mouse over it, and in this case the tooltip showed the System process as being responsible: Process Explorer’s tray icon corroborated my perception by displaying a mini-graph of red CPU activity. Not long after I got a new laptop several months ago, I noticed that the system sometimes felt sluggish. In this post, I’ll share how I used both Process Explorer and another tool, Kernrate, to identify a problem with a third-party driver and followed the problem through to a fix by the vendor.
#Microsoft download manager use cpu windows
Because I want access to detailed information about system processes, as well as my own, I also specify the /e option on Vista, which causes Windows to present a UAC prompt on logon that allows me to grant Process Explorer administrative rights.īecause I keep an eye out for CPU spikes in Process Explorer’s tray icon, which show up as green or red for user-mode (application) and kernel-mode (operating system and drivers) CPU usage, respectively, I’ve identified several application bugs over the last few months. Process Explorer runs otherwise hidden with tray icon that shows a small historical view of CPU activity level. Whenever I configure a new computer, I add a shortcut to Process Explorer to my profile’s Start directory that includes the /t (minimize) switch. The main way I keep tabs on things is to configure Besides keeping my computers running smoothly, my vigilance sometimes helps me spot performance and reliability problems in Windows and third-party code. I want to know if a process is running away with the CPU, causing memory pressure, or hitting the disk. First published on TechNet on Apr 07, 2008Īs you’ve probably surmised by my blog posts and other writings, I like knowing exactly what my systems are doing.
