How to Troubleshoot Runtime Error 21

There are many technical ways to explain runtime errors. For those who aren’t tech savvy, runtime simply refers to processes for applications that run on your computer. Run time errors, of course, describe instances where these processes experience issues. These errors come in many different forms, and one of the most common is runtime error 21.

What Causes Runtime Error 21?

Though many users don’t realize it, the frequent downloading of software applications and other programs result in numerous changes to a computer operating system. When these changes are made on a regular basis, they can eventually make your system very unstable, often resulting in runtime error 21.

The best way to solve this issue is to restore your operating system back to a previous state with a Windows function known as System Restore. Several users have reported this error after opening unsolicited messages on social networking sites like MySpace and Facebook.

After running their virus scanners and delving further, many of them learned that it was simply a run time error that could be fixed through the System Restore utility.

What is System Restore?

System Restore is similar to an undo button and has the ability to quickly fix your computer with ease. Whenever you want to reverse some of the changes made on your system, this is the first step you should make.

System Restore fixes run time errors by allowing your system to revert back to a point where it ran efficiently. Using this utility will not impact any personal files created in word processing applications, photos or software programs you manually installed. It will, however, take away those that were downloaded online and possibly eliminate your runtime error 21 issue.
 
To launch the System Restore utility, open the “Start” menu and select “Control Panel.” Navigate and click on “System or “System Tools.” Inside of this window, find and click on “System Restore.” A wizard will display and provide you with step by step instructions on restoring the system. Getting rid of the runtime error 21 is often as simple as finding a date on the provided calendar before the error occurred and saving it.

You can also create your own restore points to revert back to a time where you feel the system performed best. This is the easiest way to manually fix runtime error 21 and restore your system back to its previous functionality. If you choose to reinstall some of the applications that were removed, be sure not to install the one that stirred up all the trouble.

Saying Goodbye to Runtime Error 21

System Restore is a very useful tool, but there may be instances where it can’t resolve your run time errors. This is because it will only allow you to revert back to a certain point which limits your ability to remove every single error you encounter. Many experts recommend the use of registry cleaners for the simple fact that a majority of these issues exist because PC users do not regularly cleanup the system registry. These programs will sweep out the registry and often fix any run time errors you are experiencing.
