Why does the registry need periodic cleaning?
The Windows registry is a huge database of many entries and in order to keep it in good shape, it is necessary to perform periodic cleaning. Usually the most litter in the registry appears after an application has been uninstalled from the computer but the uninstallation script hasn’t removed the respective entries from the registry. When there are many such obsolete entries, the computer starts to slow down. Sometimes the remnants are not harmless and they can lead to corruption of the registry, which in turn can make the computer unusable. So, if you want to avoid such unpleasant situations, clean your registry from time to time.
