PC PitStop Optimize 3 Home

PC Pitstop's Optimize was originally introduced as a breakthrough application that could help you get the most out of your PC. Since then, over 150 million scans have been run at PC Pitstop and Optimize has become the world's most popular computer optimization software. Optimize 3.0 is an incredibly powerful tool that will boost the overall performance of your computer and resolve many of the issues you may be experiencing.

PC Pitstop Optimize performs four main functions: removes "junk" files to free up disk space; adjusts Internet settings for better performance; removes invalid registry keys; and adjusts several registry settings that can improve overall performance.

Windows often forgets to clean up many files that are no longer needed by the system. The space taken up by these files can clog your disk and cause slower disk access. These files are in three major categories:

Recycle Bin. Files are not actually removed from the drive when you delete them with Explorer. Instead, the files are moved to the Recycle Bin where you can retrieve them if you later decide that you should not have deleted them. Optimize empties your Recycle Bin to reclaim this disk space.

Internet Cache. Internet Explorer creates temporary files that are not needed after you finished surfing. These files can take up large amounts of space and should be removed periodically. Although you can clear the cache in Internet Explorer, Optimize uses a more thorough method that deletes files left behind by IE.

Temporary Files. Windows and applications create various temporary files that are not needed after the application exits or Windows is shut down. In many cases, however, the applications do not always clean up after themselves.

Optimize has three parts that changes your system registry, internet optimization, registry cleaning, and system performance optimization. The settings changed in the internet optimization part of the application are set according to your connection type. Settings that may be changed for Internet optimization include:

• Maximum Transfer Unit(MTU) The maximum packet size that is sent and received over the internet.
• TCP Receiving Window Size The amount of data that is received before confirmation.
• Default Time to Live The length of time the data is kept before being discarded.
• Automatic MTU Detection Allows your system to identify the MTU size.
• Blackhole Detection Checks if connected systems supports Automatic MTU discovery.
• Large TCP Windows Support for larger amounts of data before confirmation of received.
• Fast retransmission and recovery Allows for a fast transaction recovery after lost packets.
• Selective Acknowledgements Allows for recovery without re-sending existing data after lost packets.
• Number of Allowed Simultaneous HTTP Connections Number of open connections to a single web site at one time.

Invalid keys that are removed from the registry cleaning part of the application are entries in the registry containing information about COM and ActiveX objects. These objects are parts of programs and when you remove the programs these keys sometimes still exist. Optimize safely removes these keys if the COM object no longer exists. Areas of the register we look for the invalid keys are:

• Invalid Class IDs(CLSID)
• Invalid Program Identifiers (ProgID)
• Invalid Type Libraries (TypeLib)
• Invalid Interfaces
