By the end of this article, you will know multiple ways to fix the Steam Bad Session error on Windows 11, from basic checks to more advanced troubleshooting.
Quick Note: What to Check Before You Begin
- Internet Connection: Make sure your internet is stable. A poor connection can cause session errors.
- Steam Server Status: Sometimes Steam servers are down. You can check their status online to ensure the problem is not on their end.
- Windows Update: Ensure your Windows 11 system is up to date, as outdated software can cause compatibility issues.
- Steam Client Version: Confirm that you are running the latest Steam client version. Steam usually updates automatically, but you can manually check.
Step 1: Restart Steam and Your Computer
Sometimes, simply restarting Steam can clear temporary glitches causing the bad session error. Follow these steps:
- Close Steam completely. To do this, right-click the Steam icon in the taskbar and select Exit.
- Open the Task Manager by pressing
Ctrl + Shift + Esc. Look for any Steam-related processes still running and end them. - Restart your computer to refresh your system and network settings.
- After the restart, launch Steam again and try logging in.
Why this matters: Restarting clears any stuck processes or corrupted sessions that may have caused the error.
Step 2: Clear Steam’s Web Browser Cache
Steam uses an internal web browser for its interface, and corrupted cache files can cause login issues. Clearing them can help:
- Open the Steam client.
- Click on Steam in the top-left corner and select Settings.
- In the Settings menu, go to the Web Browser tab.
- Click on Delete Web Browser Cache and then Delete All Browser Cookies.
- Close Steam and reopen it to test if the error is gone.
Why this helps: Clearing cache removes corrupt or outdated files that might interfere with Steam’s session handling.
Step 3: Log Out of Steam Completely and Log Back In
Sometimes your login session might be corrupted. Logging out and back in can refresh the session:
- Open Steam.
- Click on your username at the top-right corner and select Logout.
- Confirm the logout and wait a few seconds.
- Log back into your Steam account using your credentials.
Why this works: This forces Steam to create a new session, which can fix bad session errors caused by corrupted login tokens.
Step 4: Run Steam as Administrator
Running Steam with administrative privileges can fix permission-related issues that might cause session errors.
- Close Steam completely.
- Right-click the Steam shortcut on your desktop or in the Start menu.
- Select Run as administrator.
- If prompted by User Account Control, click Yes.
- Try logging in again and see if the error persists.
Why this matters: Admin rights allow Steam to access necessary files and network features that might be restricted otherwise.
Step 5: Delete the ClientRegistry.blob File
The ClientRegistry.blob file stores important Steam client data. Sometimes this file becomes corrupted, leading to session errors.
- Close Steam completely, ensuring it is not running in the background.
- Navigate to your Steam installation folder, usually found at:
C:Program Files (x86)Steam. - Locate the file named
ClientRegistry.blob. - Delete this file or move it to another folder as a backup.
- Restart Steam. The file will be recreated automatically.
Why this helps: Removing corrupted files forces Steam to rebuild them, which can resolve session-related issues.
Step 6: Flush Steam’s Configuration and DNS Cache
Steam stores some configuration and DNS data locally, which might cause problems if outdated or corrupted. Flushing these can help.
- Close Steam completely.
- Press
Windows + Rto open the Run dialog. - Type the following command and press Enter:
steam://flushconfig - A confirmation window will appear; click OK.
- Restart Steam and check if the error is fixed.
Why this is useful: This resets Steam’s configuration settings and clears cached data that might be causing the bad session error.
Step 7: Check Your Firewall and Antivirus Settings
Sometimes, your firewall or antivirus software might block Steam’s connection, causing session errors.
- Open your Windows Security settings or your third-party antivirus program.
- Check if Steam is allowed through the firewall.
- If Steam is blocked, add it to the exceptions or whitelist.
- Temporarily disable antivirus or firewall and try launching Steam again to see if the error is resolved.
Important: Remember to enable your firewall and antivirus again after testing for security reasons.
Alternative Method: Use Steam’s Beta Client
If the problem persists, switching to the Steam Beta Client can sometimes help, as it includes the latest fixes:
- Open Steam and click Steam > Settings.
- Go to the Account tab.
- Under Beta participation, click Change.
- Select Steam Beta Update from the dropdown menu and click OK.
- Restart Steam to apply changes.
This method allows you to use the latest Steam version, which might have fixed bugs related to your issue.
