crss.exe constant I/O reads RRS feed

  • General discussion

  • Hi,

    Does anyone know why crss.exe keeps reading from the HDD every 2 seconds or so?

    The machine has been left idle all day with no apps running and it is still doing it.

    Thanks

  • The csrss.exe process is, in most cases, a legitimate and highly critical Windows component that should never be disabled. The name stands for "Client/Server Runtime Sub-System." It's the user-mode component responsible for managing console windows, process threads, and some legacy portions of the old 16-bit DOS runtime (hence its management of the console process). The running process additionally handles Windows and graphics functions for all subsystems.


    It may also happen when there is a high CPU usage. You can just perform a full scan of your computer to resolve this issue.

    Here is the link to perform online scan:

    Remember, the "real" copy of csrss.exe is a critical Windows file and should never be removed, modified, disabled, or renamed. Doing so is certain to cause major problems, and will probably render your machine unbootable.

  • Hi,

    It is a genuine process, I am just wondering why it is constantly touching the disc all the time. Logging perhaps?

    The PC in general is very quiet, but the constant click click of the HDD every 2 seconds is a bit distracting!

    Thanks

  • Could you please provide a legitimate answer for this question?

    I am facing the same problem and it is proving very difficult to track down, even for a power user.

    It's quite disappointing to see such a canned response that obviously assumes the user is clueless when the issue is actually quite important for a laptop.

    Cheers!

  • Process explorer does that.
