Symptoms of Registry Errors
The registry is critically important to the smooth operation of any Windows computer. Since settings for nearly every program which may be running on a given machine are stored there, inappropriate changes to registry values can cause significant problems. Of course, external programs can be uninstalled and reinstalled to correct setting discrepancies as a last ditch option. In fact, operating system settings are also stored here which can mean even more significant issues if recklessly or accidentally altered. These errors can present themselves in a large variety of ways. At times, the obstacle you run into may only be overcome by altering values directly using the registry editor. Not all possible settings that may be changed have a graphical user interface to make manipulating them intuitive. While the built-in editor is functional, some individuals may choose to use more advanced third party editors or cleaners. These programs are capable of making registry error correction a less tedious experience, if used properly.
Some users may run into registry based issues when attempting to run some types of scripts on most of the previous Microsoft Windows versions. By default for security reasons this is usually disabled to prevent the execution of certain types of malicious software. There is no option within any "Control Panel" sub-program which will allow you to enable this access, but a careful look within the actual Windows system folder settings using a registry editor will allow for the manipulation of that value. One must pay close attention to their symptoms and take careful note to find their answers, as there are so many third party programs which are all different and may experience problems at one time or another.
Registry error symptoms are likely to present themselves during the installation or removal of third party software. One such example may be in the event that you check your "Add/Remove Programs" list and notice that some programs which you had previously uninstalled still appear somewhere on it. Often the entry will display incomplete information or a very low file size in the summary. This may occur because the uninstaller that was packaged with the program during installation failed to completely remove the changes it made to your computer. Conversely, some programs are not provided with an uninstaller at all and one must use the generic Windows uninstallation program. Ironically, this program too occasionally suffers from the inability to remove all files and settings, manifesting the same symptoms. Removing all registry values related to that program can potentially solve this issue. To do so manually means sorting through the fairly logically structured registry tree. The values will be labeled clearly so the task is usually not excessively difficult, but may be tedious depending on the complexity of the program. Again, a registry cleaner is helpful here and can avoid this type of disorder and fragmentation.
While some registry errors a minor, others can actually cause such interference that the computer dumps its memory and restarts. When this happens, you will see a blue screen with a brief explanation of the registry-related error. Occasionally this will happen after certain system changes are made improperly. You may not be able to successfully boot into your operating system until the setting is restored to its previous state. In this circumstance, when attempting to restart a dialogue will appear which gives one the option to either "Start Windows normally" or "Use last known good configuration." Choosing the second option will revert the operating system back to the state it was in before the setting was changed. If this type of error occurs, you may lose any unsaved data, so be sure to save your work frequently.
To find out where to look for the solution to your particular error, always be sure to copy it verbatim and use a search engine to submit the message in quotation marks. Chances are, someone has had the type of registry error you have and made a similar query and requested the location of the value that needs to be changed. There are many online forums with experienced users who are there solely to help others with such problems.
