Hi,

I notice that when I first open Task Manager, the CPU % usage value for csrss.exe can sometimes show up anywhere from 33% to 90% for like half a second, then goes down to 0%. When it's around 33%, usually System is around 33% for half a second as well, as is taskmgr.exe.

Is that normal? Do those things boost up like that momentarily just from the process of opening Task Manager?

Thanks for answering yet another weird question for this curious newbie! :flowers: :thumbsup:

Can be caused by corrupt profile or power options.

I think you might have misunderstood my post... It actually isn't eating system resources consistently, as far as I know. It only shows up spiked like that as soon as I open Task Manager, then immediately goes down to 0%. I suppose it's possible that it's spiked all the time when Task Manager is closed, and only goes down once I open it, but I'm not sure if that's even possible...? However, note that my system is not running slow that I know of...

Also, I have my Power Scheme set to Portable/Laptop since it's a laptop. I think that's the more proper one to use than "Always On", is that correct? Anyone know the difference? I know when I had it set to "Desktop" accidentally, it caused my fan to constantly turn on and off.

Any further thoughts? Thanks!

csrss.exe is the main executable for the Microsoft Client/Server Runtime Server Subsystem. This process manages most graphical commands in Windows. This program is important for the stable and secure running of your computer and should not be terminated.


FYI - this doesn't happen on my virtual machine - but I use the minimum graphics necessary to get the job done - your choice of display options could cause this to jump a bit. But 33% - I really don't know enough to even hazard a guess. Any other problems with the system?
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

Don't know if this will help or not but here it is if you want to take a look.

THis file is supposed to handle the various threads of data coming in and direct them to the proper place. A quick check will be to click open task manager and go to processes tab in the pop-up menu that appears. There you will see the csrss listing. Next to it will be a listing for memory usage. If this changes a lot,be suspicious.
Also right-click on the csrss.exe and select the end process . If Windows won't remove it,you will know ttat it's the valid one.
Next examine the startup file folder. Right click start and select exlore. In the list of folders in the column on the left of the Windows Explorer that appears,look for startup and open it. If csrss.exe is there, delete it. That may solve the problem.

No other problems (well, no problems at all, really), just notice this and was wondering.

And I don't have anything listed in that Startup folder.
