Why The Registry Slows Down A System

As the registry gets older with constant use, it gets updated every time there is a change in the system. This change may be some program that has been added to or removed from the system or some hardware that has been added or removed. The registry updates its records with the change. However, not all the registry entries may be deleted when a program or hardware device is uninstalled. So, when a program requests the registry for some information the registry starts searching from the beginning of the database. It will go through all the entries one by one.

This will include all the redundant entries, which may be tens of thousands in number; this slows the system down drastically. The redundant entries are entries that are linked to the programs or hardware that have been uninstalled from the system. So, as you see, these entries are no longer needed but the registry scans them all the same. A good free Spyware Removal program will remove these obsolete entries from your system so the registry will no longer scan them. Making the system faster and more efficient.

Spyware installs itself on the system making hundreds of entries in the registry. When the anti virus utilities detect and remove the Spyware it leaves traces of it in the registry because anti virus is not designed to scan the registry. Only special Spyware removal tools can achieve this formidable task. The good anti Spyware such as free windows Microsoft Spyware remover utility can effectively remove all traces of Spyware from the registry to stabilize the system once again and make is joy to work on the PC.
