Windows 7 CSRSS Process RRS feed

  • Question

  • I installed Windows 7 Build 7100 on a Hp workstation. After doing windows updates which included drivers for my Nvidia Quadro FX 1300, the csrss.exe process is hogging up the system running constantly at 75-100%. I've tried doing the driver installs right from the home sites, but nothing seems to prevent it from happening.

    Any help would be greatly appreciated.

  • Hi

    Client/Server Runtime Subsystem, or csrss.exe, is a critical component of the Windows operating system. It provides the user mode side of the Win32 subsystem and is included in Windows 2000, XP, 2003, Vista, Server 2008, and Windows 7.

    The Quadro FX 1300 doesn't appear on the list of adapters that are compatible with Windows 7.

    The latest drivers for that device are here 32-Bit  ForceWare Release 95 and 64-Bit ForceWare Release 95
    these were designed for Windows Vista.

    You might want to try installing these drivers in compatibility mode for Windows Vista.

    HOW TO: Install a Hardware Device Driver using Compatibility Mode

    Hope this helps.

    Thank You for testing Windows 7

  • I agree with the Ronnie’s opinion.


    Firstly, we should understand the Microsoft Client Server Runtime Server subsystem utilizes the process csrss.exe for managing the majority of the graphical instruction sets under the Microsoft Windows operating system. As such Csrss.exe provides the critical functions of the operating system, and its termination can result in the Blue Screen of Death being displayedCsrss.exe controls threading and Win32 console window features. Threading is where the application splits itself into multiple simultaneous running tasks. Threads supported by csrss.exe are different from processes in that threads are commonly contained within the process, with various threads sharing resources within the same process. The Win32 console is the plain text window in the Windows API system (programs can use the console without the need for image display).In mobile devices such as notebooks and laptops, the process csrss.exe is closely dependent on power management schemes implemented by the system as defined under the Control Panel option. This process should be treated as suspicious if there are two instances running. Always take note of the process location when trying to determine whether or not the process is genuine or malicious. This Windows component should be located in your Windows System directory C:\Windows\System32\csrss.exe.


    This problem related with the NVIDIA Quadro FX 1300 driver update. After checking the NVIDIA official website, we can notice that the NVIDIA Quadro FX 1300 did not list in the list of the adapters, which are compatible with Windows 7. The link is:


    Also, after checking the driver on the NVIDIA official website, the Windows 7 driver is also the Windows Vista driver, we can install it on the computer to make sure the computer run properly. The driver links are below:






    Now, there are two methods to solve this issue:


    1: Use System Restore to make the computer back to before installing this driver update, and then hide this update.


    2: Uninstall this driver update and roll back the driver in Device Manager, and then hide this update.


    Remove the driver update


    1. Please click the "Start" Button, and click "Control Panel".

    2. Click "Control Panel Home" from left panel.

    3. Click "Programs".

    4. Under "Programs and Features", click "View installed updates".

    5. Select the update and click the "Uninstall" button.


    The driver update is one special kind of update for the system, it is a option update. If the computer and driver work properly on the computer, we no need to install the driver update on the computer. After installing the driver update, we cannot guarantee all drivers will work on all hardware platforms as there are too many different models, although their hardware ID are the same as the standard version. (The Windows Update site lists driver updates based on hardware ID scan results.)


    We can follow the below steps to hide this driver update:


    How to hide an update in Windows Vista


    1. Click the "Start" Button, click "All Programs", and click "Windows Update".

    2. From the left panel, click "Check for update".

    3. After receiving the scan results, please click "View available updates" under the "Install updates" button.

    4. Please right-click the update, and click "Hide update". If you are prompted for an administrator password or confirmation, type the password or provide confirmation.


    Hopeful the above information can help you solve this issue.
