The Windows registry is a huge database that stores all settings, configurations, software drivers etc for your operating system. All actions and changes made in your system are reflected in the registry by means of registry entries. Many of these entries are redundant and need to be removed, as they negatively impact your PC's performance. If you want to clean registry manually, this will take a lot of time, so the best option here is to use specialized registry cleaner software. Windows doesn't provide any native registry cleaners, so you should look for registry cleaner downloads.
Choosing the Best Registry Cleaner
There are plenty of PC registry cleaners available online; some websites even offer registry cleaner free downloads. However, you should be very careful with your choice and not believe the very first search result for the "top registry cleaner" keyword. Specifically, malware and spyware programs can disguise themselves as "best registry cleaners" and turn your system into a mess instead of performing registry cleanup. Therefore download registry cleaners only from trusted sources!
Most PC registry cleaners are free of charge or have a trial period. You can download and compare several registry cleaner programs to choose the one that suits you best. It will be also helpful to read online reviews from registry cleaner software users.
Two main features of a good computer registry cleaner are ease of use and efficiency. Apart from other PC maintenance programs, a registry cleaner does not have to be lightning fast, as sometimes the registry may contain too many errors. Let the scan take some time but find and remove all errors in the end.
