Perfect Optimizer is an advanced registry analyzer and optimizer that can boost your computer's performance and improve the overall speed of your system. It offers an extremely powerful and stable scanning technology, and complete protection against data loss during the optimization process. It also features a powerful defragmentation engine that allows you to improve the access to the system registry by optimizing disk accesses to the files that comprise your Windows registry.
Registry Cleaner
The first step when you choose the Registry Cleaner is to select which categories you would like to scan for errors: By default, all categories are selected. We're proud to say that our engine is a world leading custom advanced tool that is unbeatable.

Simply click 'START SCAN'... to begin advanced scanning of your system. This will start the actual scanning process. As the scan goes on, you will see a progress report window that shows you at all times the number of errors found and the scan progress. You can choose to pause the scan at any time by pressing ABORT or Cancel the scan. After the scan has finished, your data will be backed up automatically to preventing you from losing any data. Once the backup process has finished, you should see the scan results: Now simply click the 'REPAIR ALL' button to repair all the errors and create a backup of all changes made automatically.
Defragment
You can choose to defragment the system registry using this feature, and analyze current registry fragmentation: Click the ANALYSIS button to verify if the system registry is fragmented or not. If your registry is not fragmented, you should see a screen similar to this one: If your registry is fragmented, you can now choose to defragment your registry by pressing the Defragment button, or Cancel the defragmentation.

Once you choose to defragment your registry, you will have to reboot the computer for the defragmentation to occur - this is caused by Windows locking access to the files that need to be defragmented while your operating system runs. If your registry is not fragmented, you will see a message telling you that you do not need to defragment your computer.
PC Optimizer
This feature allows you to tweak your system for maximum performance, based on your computer's profile. You need to select what best describes your computer from the list present in this dialog box, then click the Next button to proceed further and examine how your computer will be tweaked, or click the Fast Optimization button to apply the changes immediatly.

Optimize Memory
Your computer needs memory in order to run programs and perform different tasks. Sometimes, your memory gets filled and your computer reacts very slow. This feature allows you to "un-freeze" your system's memory, freeing up as much memory as necessary in order to allow programs to run and perform faster, and in order for you to be able to start and use even more programs.
