The Windows Vista operating system is both similar and different in many ways to the previous Windows operating systems.  One way it’s similar is in the Windows registry.  The registry was always notorious for getting cluttered and corrupted.  Thankfully there are registry cleaners that are compatible with Vista and Vista certified.  The best Vista registry cleaner is definitely RegCure by ParetoLogic software.  This is the program I personally use and I find it to be very effective and fast.  Definitely look into this program as a solution for your registry needs.  There’s a free trial scan so you can see if you need it.
