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:
After scanning your system, PC Matic gives you the option to review the files that it found and to select which files should be deleted.
PC Matic 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. PC Matic safely removes these keys if the COM object no longer exists. Areas of the register we look for the invalid keys are:
The performance section of the application changes some registry settings that help get the most out of your PC. These setting include:
|DisablePagingExecutive||Specifies whether user-mode and kernel-mode drivers and kernel-mode system code can be paged to disk when not in use.|
|ContigFileAllocSize||The size of the contiguous space that is used for when allocating disk space|
|NtfsDisableLastAccessUpdate||Determines whether NTFS updates the last-access timestamp on each directory when it lists the directories on an NTFS volume.|
|DisableScreenSaver||Turns the system screen saver on or off.|
|AlwaysUnloadDll||Determines whether Windows cache's system DLLs.|
|LargeSystemCache||Determines whether the system maintains a standard size or a large size file system cache, and influences how often the system writes changed pages to disk.|
The hard disk clean-up permanently removes unnecessary files and cannot be undone. All of the other utilities in PC Matic can be completely reversed. The very first action PC Matic does before making any registry setting changes is to make a backup of these settings. When you run PC Matic it will give you the option to restore the registry settings back to any point before the application was run.
