My laptop is running low, I guess it's because there are too many unused files or registry. I need to clean up my computer and speed it up; I just searched online and found that software get such functions all need to pay:(...So, can anyone recommend a free download system-care software??
 
I use CCleaner by Piriform as someone has already suggested. Just google CCleaner and download the free version. It will delete all your temporary/unnecessary files.
 
What Operating system are you using? I like using C Cleaner as people have mentioned or Microsoft One Care Full system scan.
 
Registry cleaners/optimizers are not recommended for several reasons:


  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.


 
CCleaner is a fine tool, as long as you don't use registry cleaner part.

There are some other fine cleaners, which don't deal with registry at all.

1. Download Temp File Cleaner (TFC)
Double click on TFC.exe to run the program.
Click on Start button to begin cleaning process.
TFC will close all running programs, and it may ask you to restart computer.

2. Download ATF Cleaner by Atribune.

Double-click ATF-Cleaner.exe to run the program.

I'm running Windows 7 on my laptop. CCleaner does not work completely:confused:, there are still some registry files can not be cleaned.
 
Registry cleaners IMO are just snake oil. I have yet to see one that actually does anything as far as speeding up a computer. They usually just cause problems, and not do anything productive really besides delete random stuff. For speeding up your computer, I would put your effort elsewhere :good:

How do you know that? Where do you see those registry "files"?

I've used CCleaner with Windows 7. It works fine.
