2. Clean boot the system

Another solution to fixing the NET Parsing Error 0xC00CE556 involves performing a clean boot. This is a troubleshooting technique used to diagnose applications that cause errors. Third-party applications, or even Microsoft services, can conflict with the NET Framework or, you could say, with the system files. To determine which software is causing the error, you must disable all irrelevant services and third-party software by performing a clean boot to Windows. This allows just the necessary services and minimum drivers to load. If the error does not appear after performing a clean boot, it means that a third-party or Microsoft service is causing the error. To fix this, you have to enable the services one by one or half at a time to identify the culprit. Make sure to restart the computer after enabling each service. If you cannot find the culprit, you can use your Windows system in a clean boot state.

  1. To boot Windows in clean mode, click the Start Menu and type ‘MSConfig’.
    Open System Configuration
    Go to System Configuration
  2. Open the first set of settings, click on ‘Selective Startup’, and select the ‘Services’ tab from the top.
    Click Selective Startup
    Click Selective Startup
  3. Tick the ‘Hide All Microsoft Services’ option, and click ‘Disable All
