How To Fix The CS2 Disk Write Error On Steam [8 Methods]

1 /8

Restart Steam With Task Manager

Let’s start with simple fixes and get to lengthier solutions as we get more desperate. The first method is to do a simple restart of the Steam client, using the Task Manager for maximum effectiveness.

To restart your Steam client with the Task Manager, follow the steps below:

  1. On Windows 11, hold Ctrl + Shift + Esc, or hit your Windows key and search for “Task Manager”.

  2. Once the Task Manager is open, go to the Processes section and look for “Steam Client WebHelper”.

  3. Right-click “Steam Client WebHelper” and click “End Task”.

  4. Steam will completely close. Now, re-launch Steam like you normally would.

Restarting Steam with the Task Manager gives Steam a fresh reboot. If this method doesn’t work, let’s keep going.

Run Steam As An Administrator

If restarting Steam doesn’t work, you should try running Steam as an administrator. For this method, your Windows user must have admin permissions on the computer.

To run Steam as an administrator every time you open it, follow the steps below:

  1. Look for your Steam shortcut on your Desktop.

  2. Right-click Steam and go to Properties.

  3. In the Steam Properties menu, go to the "Compatibility" section.

  4. Under Settings, check the “Run This Program As Administrator” option.

  5. Click “Apply” on the bottom right corner to save and apply your changes.

  6. Your system will ask you for admin permissions to run Steam. Grant the permission.

Your Steam will run in administrator mode every time you open it. There is no reason to turn it off; it can fix other issues like black screens in CS2.
