It's likely that sometimes in your current computer's life, you have asked yourself: Why is my computer slow and how can i optimize my pc? What unfortunately most people won't realize is the fact that in many of these matters, there is a single origin of these errors: your system's registry. Having no knowledge of the registry, too many of us spend large amounts of precious time and money on getting the "spyware, virus" answer, but this most likely is not the case. Just give a shot to Free PC Optimizer DLL Tool, and your issue will be solved!


Windows Registry usually called "the registry," functions as a collection of databases of configuration settings in operating systems. The registry is used to store much of the information and settings for user preferences, hardware devices, software programs, operating system configurations, and much more.

The registry contains two basic elements: keys and values. Registry keys operate similar to folders. Registry values are like files. Keys may contain values or further keys. Keys are referenced with syntax similar to Windows' path names, using backslashes to indicate levels of hierarchy. Keys must have a case insensitive name without backslashes.

The hierarchy of registry keys can only be accessed from a known root key handle that is mapped to the content of a registry key preloaded by the kernel from a stored "hive", or to the content of a sub key within another root key, or mapped to a registered service or DLL that provides access to its contained sub keys and values.

The Windows registry can be one of the sources of the DLL errors and poor performance of your pc. The typical signs of slow windows system are as follows!


You'll obviously notice and get worried if your registry is more and more bloating. The following symptoms can be easily mistaken as a virus infection or a hardware issue, which is why it is often neglected. Here are the common symptoms of a bloated registry:

  1. Slow shutdown time
  2. Inability to boot into the operating system
  3. Software fails to start or frequently crashes
  4. Your computer is generally unresponsive or slow

But with these symptoms, you can hardly make sure it's related to registry bloat. The best way to figure it out is to use a PC optimizer like DLL Tool, which has a auto detection feature. When not fixed right away, it may lead to more serious problems where you need to reinstall the operating system or even reformat your computer.


The first place you check when your computer starts to run slower is the registry. Basically, the registry files contain information and settings for all of the software, hardware, operating system software, and anything else running on your computer. Mess any of these files up, and the computer does not know how to function. The computer goes to start up the software, looks for the registry files, and either cannot find it or finds something that does not look like it is supposed to look like. It then just sits there: it does not know what to do next. This is where the "freezing" or "locking up" of your computer comes from. These files will need to be fixed.


To fix the registry files, get the best PC optimizer as DLL Tool and run it on your computer. It will tell you how many files are corrupted and need to be fixed. Just tell the software to fix it and it restores all of the registry files to their correct configuration. It is really that simple. It may take only about 5 minutes to perform this check. And then as a maintenance item for your computer, I would recommend performing this registry fix at least once a week. This will always ensure your registry files are good, and keep your computer running with no slow, freezing and errors. So if you find yourself asking why my computer slow is, I would check the registry files first.

DLL Tool is able to figure out which programs are running and how heavily they're taxing your hardware at any given moment. It can be used to pinpoint performance bottlenecks and uncover weak points like outdated driver software or missing Windows security patches.

You should also keep an eye on your Windows Resource Monitor to confirm that your PC is running only the programs you need. You can temporarily shut down unwanted programs by using Boost Your Windows Startup function to optimize pc startup. It's always a good idea to delete unwanted programs to maximize space, but many useful programs that you rarely use automatically start system-hogging processes, potentially bogging down your PC's performance. To minimize this problem, take advantage of this free Windows optimizer to disable Windows startup programs that you don't use every day.

Downloading files, installing and uninstalling software, and other daily activities create messes that take up space and impact performance. DLL Tool is a housekeeper of sorts, making sure that things are tidy and functioning at their best.

DLL Tool has a comprehensive, well-organized interface that arranges its features in five tabs with four of them free of charge (except for the first one). The DLL Home is a quick scan that gets rid of the most common DLL errors such as DLL missing/not found, high CPU/memory usage due to virus infection and blue screen of death(BSOD), as well as registry bloating; the Performance digs a little more deeply to find more space-wasters. The Privacy feature keeps your personal data from being stolen while clearing the leftover of your daily operation. There's also a Recovery feature to have packaged with other cleanup tools. The most special feature of this windows optimizer is DllpediA, it allows for you to download any DLL file free whenever necessary!
