Another great tool from Auslogics is their free Registry Defrag utility. Over time, registry values can be left over from previously installed/uninstalled programs, resulting in a "fragmented" registry. What this results in is a longer start time for your currently installed applications due to your computer having to sift through the old and no longer needed registry fragments before it comes to the information it needs.
Registry Defrag examines your registry and will correct the errors it finds, resulting in faster application startup times.
