The Windows Vista operating system has developed a reputation for running slowly and even crashing and freezing. According to experts, the major reasons for Vista running slowly are registry errors or other system errors. The registry is a database of information including system and network settings and software, as well as hardware configurations. When you install or uninstall software, for example, new entries are added to the registry. But as time progresses, the registry gets too big, and makes it start to act up. This is when you see your computer start freezing, booting and working slow, and generally just running poorly.

The way to fix registry errors in Windows Vista is to use a registry cleaner utility. Registry cleaning and repair software will perform a system scan, and all invalid and unnecessary files will be identified and marked for deletion. Removing files can be done automatically by the program, or it can guide you manually through the process, whatever you choose. The best Windows Vista registry cleaners will also give you the option of performing regular system scans that you can schedule ahead of time. You don't even need to think about it. You can download a registry cleaner for free from various sites but make sure that you use one that is rated for use with Windows Vista. And before you use a registry cleaner, make sure that you back up all your system information using the Vista's system restore feature.

One important note before you use the registry cleaner: make sure that you back up all your system information. You can do this with the Windows Vista's systems restore feature that is already built into the operating system. Finally, before you buy any type of registry repair software, make sure that it is compatible with Windows Vista. If it is not, then using it could cause any number of problems for you and your computer.
