Speed up computer & optimize Windows

Do you have a slow computer? No worries. RegistryBooster speeds up your computer faster than ever by cleaning and optimizing cluttered Windows Registry, and repairing corrupted files.

Slow computer performance is a direct result of cluttered Windows Registry that contains a large amout of empty and erroneous entries. As your computer gets older, its Windows Registry gets abused and damaged by failed installations, incomplete un-installations, out-of-date hardware driver information or empty registry data never used by any active applications. Gradually, you may find that your computer performance deteriorates as Windows start up and shut down takes forever, launching applications takes longer than usual, Windows freezes more frequently, some annoying error messages pop up from time to time, and it simply crashes for no reasons.

The best solution to speed up computer and fix errors is to always maintain a clean and optimized Windows Registry using a reputable and trustworthy Windows registry cleaning and PC optimization software like RegistryBooster. RegistryBooster can easily fix your computer errors, prevent freezing, and boosting the performance of your PC.

Having PC errors? You are not alone!

Has your PC become error laden and prone to crash over time? Are you frustrated with your computer’s sluggish performance and decreased speed? You have probably tried everything, including keeping your Windows installation up to date with the latest patches, fixes and updates, adding more memory, installing larger and faster hard drives, and even upgrading to Windows Vista. But nothing seemed to prevent your PC from displaying the classic signs of poor performance and errors, including:

Slow Windows startup
EXE errors
Slow application launches
DLL errors
Applications freeze or crash
Runtime errors
Windows freezes or crashes
Java or Javascript errors
Internet Explorer errors
Chkdsk errors
Installer/Uninstaller errors
Hardware driver errors
ActiveX Control errors
Task Manager errors
Windows Explorer errors
System32 errors
Virtual Memory errors
Font errors

The risks of neglecting these errors are many. A neglected system can result in more severe fatal errors, hard drive failures, and even an unrecoverable system crash. Worst of all, you run the risk of losing all of your personal data, important files and precious digital photos when the only way to recover your PC is a complete system restore.

Why risk it all? Almost all of these common PC errors are detectable, fixable and preventable with the right tool.

Diagnose PC errors with Windows Registry

The majority of common Windows Errors are caused by issues with the Windows Registry. Almost every operation in Windows requires read or write access to the Windows Registry.  Just a few of the operations that interact with the Window registry are: installations and uninstalls, adding or removing hardware, updating device drivers, opening and closing applications, moving and resizing Windows, and modifying user account settings.  

Many Windows applications also use the Registry as a simple alternative to an external database. Because the Windows Registry is the most frequently accessed component of the entire Windows operating system, it is prone to damage if not maintained properly. Some of the problems Windows Registry experiences include:

A bloated Registry filled with empty or orphaned registry keys.
A fragmented Registry caused by frequent read and write accesses.
Erroneous data left by incomplete installations or uninstalls.
A single point of failure as a centralized database.
Registry size exceeds the Registry Size Limit (RSL) defined by Windows

When the integrity and performance of Windows Registry is at risk, it becomes a bottleneck that can affect your PC's overall stability and speed. If your PC is suffering from speed and performance issues, the problem may lie with the Windows Registry.

Computer technicians and IT professionals have many secrets, and one of the most closely guarded is the importance of the Windows registry. Learning to diagnose and repair common Windows registry problems can keep your PC running smoothly and ensure your precious data is safe for many years.

The Windows registry is a single database that stores the settings and options for the Windows operating system itself, all of the hardware contained on the system, all software applications, all user account settings and preferences and more. As a result, a complete scan of your Windows registry can provide an accurate diagnosis of the following parts of your Windows operating system:

Checks the COM/ActiveX section for invalid CLSID/Typelib/Interface entries
Checks the Uninstall Entries section for invalid or missing uninstaller
Checks the Font section for missing font files
Checks the Shared DLL section for invalid or conflict entries
Checks the Application Paths for invalid disk directories
Checks the Help File section for invalid help file references
Checks the Run section of for missing program entries for Windows Startup
Checks File/Path references for non-existing files, folders, and shortcuts
Checks the File Association section for invalid file extension associations
Identify empty Registry Keys for defragmentation

The results of a complete registry scan can give you a clear picture of your PC and its performance bottlenecks. The good news for you is that you can actually download the exact same software used by professional computer technicians to conduct a comprehensive diagnosis of your computer and its vital registry file.
