The most important tool available for Vista registry tweaking is the Registry Editor (regedit.exe), which allows you to view and manually edit the contents of Windows Registry. The window of the Registry Editor is divided into two pans of which the left side contains a tree with keys that are represented as folders. The right side shows the values contained in currently selected specific key.

The registry editing generally involves navigating down the folders to select a particular key, which you can modify with a new key or assigning a new value. You can add a new key or value by selecting New from the Edit menu of the Registry Editor. This allows you to select the option you want to add and thereafter you can type the name of the key or value. Furthermore, if you think, a key or value is of no use and it can be discarded, then you can delete it by simple selecting it and pressing the Del key on the Registry Editor. One important thing to remember while tweaking with the Vista registry is that you need to reboot your system so that the changes in the registry take effect.

You can also perform Vista registry tweaks using various Vista registry cleaners available. A Vista registry cleaner continuously scans your Windows Registry, which helps in keeping the registry up-to-date, free from unused registry entries, and also safe from different spyware and adware programs. It also offers backing up and restoring the registry whenever required and enhances the performance of your system. This enables your working in the system a better experience.
