Control Panel is a collection of tools that allow users to organise and adjust the settings of their Windows system, such as installing software, changing network settings, and so on.
Many Windows customers have recently complained that when they attempted to access the Control Panel window on the system, it would not open. They’re not sure what they can do at this stage because there are no errors or warning indicators.
Some of the things that might be causing this issue are described below.
- Corrupted system files
- Virus attack on the system
- Changes in the file association for control panel files
- Windows error reporting service might be interfering
So in this post, we have compiled a few solutions keeping in mind all the factors mentioned above that will assist the user in quickly solving the problem on their system.
Fix 1 – Check the Services responsible for this problem
Windows Error Reporting service when enabled can cause such types of problems mentioned above, where it will interfere in launching the application or tools on the windows system. Also, there is another service called Software protection, which can also be responsible for this issue when disabled.
So, we recommend our users that make sure to stop the Windows Error Reporting service and start the Software Protection service via the Services window.
Follow these steps below on how to do it.
Step 1: Open the Run command box by pressing Windows + R keys together.
Step 2: Type services.msc in the Run box and press Enter key to open the Services window.
Step 3: In the Services window, search for Windows Error Reporting service and double-click on it to open it.
Step 4: In theWindows Error Reporting service’s properties window, make sure Service status is Stopped. Otherwise, click Stop and then click OK to reflect changes and close the properties window.
Step 5: After it is done, look for the Software protection service and open it by double-clicking on it.
Step 6: If the Service status of the Software protection service is stopped, please click the Start button to start this service.
Step 7: Once it starts, click OK to close the properties window.
Step 8: Then, close the Services window.
Now check if the problem got resolved or not.
