There are several reasons why your computer could be running slow, and if you’re not sure exactly what’s causing the problem then it can be quite a hassle tracking it down.  If you’re unsure what’s causing the problems in your computer it’s a good idea to run some maintenance software to try to figure out and narrow down the problem.  One good type of software to try is a registry cleaner.

The best registry cleaner software will allow you to scan the registry for errors and then fix them for best performance.  The Windows registry is well-known to get cluttered and corrupted with obsolete and orphaned files.  This buildup then tends to bog down the computer and cause all sorts of issues.
