The "There was a problem starting C:WindowsSystem32*" error message occurs during Windows startup, indicating a failure to load the `*` file. This issue typically stems from a few specific causes and can be resolved with targeted troubleshooting.
Common Causes of the * Error
- Malware/Adware Infection: * is frequently associated with unwanted software like adware or Potentially Unwanted Programs (PUPs), such as "Search Protect by conduit". These often install the DLL without proper integration, causing errors.
- Incomplete Software Uninstall: Residual entries related to * may linger in the Windows Registry or startup list after uninstalling the associated unwanted software.
- Corrupted System File: Although less common, the DLL file itself could become damaged.
- Registry Issues: Invalid registry references pointing to a non-existent or incorrect location of *.
Quick and Effective Solutions
1. Scan for Malware and Adware
This is the most critical step. Use reputable anti-malware and anti-virus software to perform a full system scan. Microsoft Defender (built-in) combined with a dedicated anti-malware tool is recommended. Quarantine or remove all detected threats.
2. Clean Up Startup Entries
- Press `Win + R`, type `msconfig`, and press Enter.
- Go to the "Startup" tab (in Windows 10; for Windows 11, use Task Manager > Startup tab).
- Look for suspicious entries, especially any explicitly referencing `*`. Disable them.
- Apply changes and restart your computer.
Note: Exercise caution. Only disable entries you recognize as problematic or clearly unwanted.
3. Remove Registry Entries (Advanced)
Warning: Edit the registry carefully. Back up the registry first (`File > Export` in Regedit).
- Press `Win + R`, type `regedit`, press Enter.
- Navigate to these keys:
- `HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun`
- `HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun`
- Look in the right pane for any entry whose "Data" field points to `*`.
- Right-click on the entry and select "Delete".
- Restart your computer.
4. Manually Delete the File (Use with Caution)
- Navigate to `C:WindowsSystem32`.
- Locate the `*` file.
- Right-click it and select "Delete". You may need administrator permissions or to take ownership of the file first.
Important: Delete this file ONLY after performing steps 1-3 and confirming it's malware/adware related. Do not delete standard Windows DLLs.
5. Perform System File Checker Scan
To rule out underlying corruption:
- Open Command Prompt as Administrator.
- Type `sfc /scannow` and press Enter.
- Wait for the scan to complete and repair any found issues.
- Restart your PC.
6. Use System Restore
If the error started recently, use System Restore to revert your PC to a state before the problem occurred.
- Search for "Create a restore point".
- Click "System Restore", choose a restore point prior to the error appearing, and follow the prompts.
Summary
The * startup error is predominantly a symptom of removed or malfunctioning adware/malware. Prioritize thorough scanning with security software and cleaning up startup/registry references. Manual deletion of the file is a last resort after confirming it's the culprit, not a legitimate Windows component.
