Will A Registry Repair Tool Remove Important Files?


If you’ve noticed that your computer is running slowly, or that it takes a long time to load into Windows, it is likely that people have suggested you run a registry repairer to fix your issues and speed up your computer. However, you may be concerned that when you run one of these registry cleaners that your important files may be lost. While these programs will remove old and unused files from your computer, it will not remove any of your important documents or files needed to run programs on your computer.

Will a registry repair tool remove important files?

Registry cleaners work by going through your operating system’s registry files and removing ones that are no longer needed. Registry files are files that are associated with programs that you use on your computer. However, if you uninstall a program, the registry files are often left behind. When your computer goes through its startup process or goes to open a program, it has to sort through the files in the registry. If there are a large number of unneeded files, it can make this process take longer than necessary.

It is important to note that registry cleaners only look at certain parts of your operating system, specifically registry files. This means that your documents, photos and files with password protection are not at risk of being removed from your computer. Additionally, these programs only remove files that are no longer being used, so you do not have to worry about any lost data or having issues with software that is currently installed on your computer.

Even though registry cleaners are designed to be very careful about the way that they sort and remove files, they have built-in protections that ensure that your files are safe. Many of these programs offer you the ability to backup your registry before any changes are made. This means that even in the unlikely event that your computer runs into issues after you run a registry cleaner, your files can easily be restored.
