The Windows registry has confounded many a computer users.  This is a Windows feature.  Inside are stored hundreds of entries that store highly important preference and setting information that tell Windows the right way to run software and hardware.  The registry also helps keep your user settings consistent from use to use. 

The registry has a tendency of getting bloated with obsolete, broken, and empty registry files.  Since Windows constantly reads from the registry as you use your PC, all those extra files can really bog down your PC.  This is one of the biggest causes of "slow computer syndrome."

The only way to really clean the registry is to get the best registry cleaner software that you can find.  This is the easiest and safest way to deal with registry problems.  Registry repair software programs are a great way to give your PC a speed boost and get it running like the day you bought it. 

Remember it is not recommended that you try to tinker with the registry by hand.  This could lead to even bigger problems.  Your computer might not even start up again if you remove the wrong registry entry.
