The Windows Database, as the name may suggest, is a huge database for all the programs, processes and events that occur in Windows. Every option, setting and preference for Windows applications is referenced through the Windows database, along with options and configurations for hardware. As a central hub for Windows activities, the healthy operation of the Windows Database is absolutely crucial. The Windows Database, with its importance, is correspondingly large and complex. An error here can have drastic effects throughout your system. To see what kind of errors and junk data are cluttering up your Windows Database, run a SpeedyPC scan. To reveal all the items, be sure to select each scan category.

Problems in the Windows Database can have a number of causes. Improper installation or uninstallation of software can lead to bits of information left over, cluttering up the database and potentially leading to error messages. These can range from DLL errors, Font errors, Help File faults, and more. Viruses and other malicious software can be another cause. There are many fine security programs which can remove viruses and other threats. However, their goal is only to remove the danger of the infection. Often, the security program will remove the infection, but will leave behind scattered entries in the Windows Database. These leftovers do not have the danger of a virus or malware, but can still clog up and slow down the operations of the registry.
