  • Introduction to the Registry
    • The registry is a system-defined database in which applications and system components store and retrieve configuration data, information and settings for all the hardware, operating system software, most non-operating system software, users, preferences of the personal computer, etc. The data stored in the registry varies according to the version of Windows used.

      Note: in the latest Windows versions - Windows XP, Windows Vista and Windows 7 - the registry does not physically exist as a single file, it is a virtual entity composed of different files in the system, some of which are created during the system boot and exist only during the Windows user session and are deleted once the computer is shut down.

      If there is an error in the registry, your system may not function properly. PC Win Booster helps you scan your registry for some possible problems and try and fix them to improve the overall computer performance.

      Note: most of the registry changes in Windows versions require a user to have Administrator permissions to perform them; in Windows Vista and Windows 7 you will additionally need to run the program as administrator to get the full access to all the program features.

      Note: it is not recommended to edit the registry data unless it is absolutely necessary, that is your computer experiences slow performance issues, some programs behave inadequately and so on. Please make sure you create a backup each time you scan and fix some registry problems.

      The registry contains the following root hives:

      • HKEY_CLASSES_ROOT (HKCR) - stores information about the system registered applications, such as file extensions tying them to the applications used to handle these extensions. In fact this hive combines data from the HKLM\Software\Classes and HKEY_USERS\Current_User's_SID_Classes registry sections.

      • HKEY_CURRENT_USER (HKCU) - stores settings that are specific to the currently logged-in user.

      • HKEY_LOCAL_MACHINE (HKLM) - stores settings that are general to all users on the computer - information about system hardware drivers, services, software and Windows settings.

      • HKEY_USERS (HKU) - contains subkeys corresponding to the HKEY_CURRENT_USER keys for each user profile actively loaded on the machine, though user hives are usually only loaded for currently logged-in users.

      • HKEY_CURRENT_CONFIG - contains information gathered at runtime; information stored in this key is not permanently stored on disk, but rather regenerated at the boot time.

      Below is the list of registry sections, which are scanned by PC Win Booster:

      • COM/ActiveX - registry section in which the COM-servers used by various applications are registered (in-process servers (.dll files) or out-of-process servers (.exe files)). The program scans for the .dll or .exe links in the registry that point to the nonexistent files on the computer hard disk drive. A COM-server can also link to a type library (usually a .tlb-file) that does not exist. In case the DefaultIcon registry subkey is present in the category, the program will also scan for the presence or absence of the file containing the file icons.

      • Application Paths - registry section used to store the full paths to the applications launched using the Run window or command prompt. The program scans for the nonexistent paths to the applications and deletes the entries if these files could not be found.

      • Uninstall Entries - registry section used for programs installation/deinstallation paths entries. The program scans for the nonexistent paths to the applications installer/uninstaller files and deletes the entries if these files could not be found.

      • File Extensions - registry section used to store the full paths to the applications, file icons and additional commands associated with the file extensions. The program scans for the nonexistent paths to the applications and deletes the entries if these files could not be found.

      • Windows Fonts - registry section used to store the full paths to the Windows fonts or the font file name (in this case the font file must be present in the \Windows\Fonts\ directory). The program scans for the nonexistent paths to the font files and deletes the entries if these files could not be found.

      • Help Files - registry section used to store the full paths to the Windows programs helps. The program scans for the nonexistent paths to the helps files and deletes the entries if these files could not be found.

      • Internet Explorer typed URLs - registry section used to store the history of the URL-addresses typed in the Internet Explorer address bar. The program scans for the presence of these entries.

      • Explorer MRU list - registry section used to store the history of the entered Run window commands, recent documents list, last visited pages and opened and saved files. The program scans for the presence of these entries.

      • Search Assistant MRU list - registry section used to store the history of the entered Search window commands. The program scans for the presence of these entries.

      • Media MRU list - registry section used to store the history of the latest media files played by the Windows Media Player. The program scans for the presence of these entries.

      • Shared DLLs - registry section used to store the full paths to the library files (DLLs) that can be used by several programs. The program scans for the nonexistent paths to the files and deletes the entries if these files could not be found.

      • Sounds and App Events - registry section used to store the full paths to the Windows sound files used by various applications. The program scans for the nonexistent paths to the sound files and deletes the entries if these files could not be found.

      • Windows Startup - registry section used to store the full paths to the applications which are executed automatically during the system startup. The program scans for the nonexistent paths to the files and deletes the entries if these files could not be found.

      • Windows Applications - registry section used for programs installed on PC. The program scans for the nonexistent paths to the files and deletes the entries if these files could not be found.

      • MRU Cache - registry section used to store the history of the entered applications. The program scans for the nonexistent paths to the files and deletes the entries if these files could not be found.

      • Invalid Firewall Settings - registry section used to store the list of authorized applications for Windows Firewall. The program scans for the nonexistent paths to the files and deletes the entries if these files could not be found.

      Note: PC Win Booster searches not only the HKEY_CURRENT_USER registry hive, but also the HKEY_USERS that store data for all the users on the computer. Please make sure you do backup your windows registry before you fix the existing problems.

  • Introduction to the Defragmentation
    • Defragmentation is the process of locating the noncontiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file. Defragmentation reduces data access time and allows storage to be used more efficiently. Some operating systems automatically defragment storage periodically; others require that the user occasionally use a special utility for this purpose.

      Defragmentation is advantageous and relevant to file systems on electromechanical disk drives. The movement of the hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the entire contents of a non-fragmented file sequentially without moving the read/write heads to seek other fragments.

      A common strategy to optimize defragmentation and to reduce the impact of fragmentation is to partition the hard disk(s) in a way that separates partitions of the file system that experience many more reads than writes from the more volatile zones where files are created and deleted frequently. The directories that contain the users' profiles are modified constantly (especially with the Temp directory and web browser cache creating thousands of files that are deleted in a few days). If files from user profiles are held on a dedicated partition, the defragmenter runs better since it does not need to deal with all the static files from other directories. For partitions with relatively little write activity, defragmentation performance greatly improves after the first defragmentation, since the defragmenter will need to defrag only a small number of new files in the future.

      Note: PC Win Booster scans local drives and makes decisions, whether defragmentation is needed to the each local drive.

      Note: Defragmentationis is a very long time process so in PC Win Booster there is settings “shutdown the computer after fixing”.
