Stop running this script?A Script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive. This occurs when some scripts take an excessive amount of time to run. To be precise, there are some websites that use JavaScript, JQuery, and Active X scripts to run. These scripts are notorious for taking too much time to run. So, if you use the Internet Explorer as your web browser, then by default if the website takes a long time to load, the ‘Stop running this script error will be triggered. Other than this, if you are scripting an Active X control on the web page to transfer a very heavy file or run a huge database query, this may cause delays and lead to the error display. However, if you use Firefox, then the ‘Stop running this script error code will be promoted as ‘Unresponsive Script’ error.
Error CausesError 0xc0000142 can occur in any of the Windows versions and usually occurs when an application fails to properly initialize.
This error can be critical for a computer as it signifies that the system is unstable. Error 0xc0000142 can cause slow performance in a PC, system freeze, startup and shutdown issues, blue screen and errors in installation.
Error CausesWindows/Application Error 0xc0000142 can occur because of a number of reasons.
When a computer is an overload with data, or when system files get broken or missing, this error can occur and will result in startup and shutdown issues as well as the blue screen. Another reason, and one which is quite common, is improper computer maintenance.
This will cause a PC to perform slow, system freezes, and installation errors. This error displays ‘failed to initialize’ on either a Windows error box or the blue screen of death.
Error 0xc0000142 can occur at any time, but there are many ways to resolve it. For instance:
A corrupted registry is one of the major reasons why this error occurs. The registry is used by Windows to store information and settings on the computer, which is why it has a large database.
This database contains emails, wallpapers, saved passwords and much more in ‘file path references’. These allow Windows to run the common files in your system. A registry cleaner can fix any errors in the registry database.
Viruses can cause certain applications to not function properly. Hence, download a strong antivirus and run a deep scan on your system and remove any potential infections and spyware.
Non-critical applications in a computer are those that are installed by the user. If error 0xc0000142 displays in any of your installed programs, then you should reinstall these programs.
