The registry is a database that tracks information on installations and changes to settings. It is constantly being updated and consistently grows larger each time a change is made. Windows accesses the information in this database to run the programs you use. The larger the registry is, the longer it takes for the computer to start and run your programs.
When programs are deleted all of the associated registry files should be deleted too. But, sometimes files are left behind. Because the program no longer exists on the computer these orphan files have no use. They simply take up room in the registry and slow the computer down.
Surfing the web carries some risk. If you don’t have robust protection software, malicious files will install themselves in the registry. You won’t see them arrive and you will not know they are there until they do their damage.
As the size of the database increases, performance slows down. This is because it references all entries to find information whether it is relevant or not.
Software that checks the Windows registry and scans for unneeded files is available. The software will show you the files that have no legitimate purpose and let you decide whether you want to delete them. When you select the delete option the files are removed permanently. In essence the software cleans the registry.
Not many general computer users have the skills to clean the Windows operating system registry manually. And, even those who do would usually not take this path when a computer program can do it in a fraction of the time.
Can you afford to have your computer’s performance decline? Or, get to the point that it crashes or won’t boot properly? Once that happens, it will probably be too late to use a cleaner. Instead you will have to call a technician and pay them whatever they ask to get it running again.
Regularly running registry cleaners can protect you from poor computer performance. Before you go out and buy upgrades, or call a technician to find the problem, run a cleaner. It is likely this will improve your computer’s functioning substantially.
