Understanding Windows Registry

I had a question about registry cleaners and just what exactly the registry on your Windows PC is?

Basically, the Windows Registry is a database used to store system and program settings.

Here’s what mine looks like:

So, for an example, let’s say a particular program gives you the option of setting its font. You select a font on its font selection screen and hit OK. When you hit the OK button, *most* kinds of software will make an entry into the registry. Next time you run the program, it retrieves the information you set, in this case the font style.

That brings me to the question of whether or not you need a registry cleaner? There are some popular registry cleaner programs out there like CCleaner that some folks swear by.

But the consensus among most experts it that you really don’t need one and there’s always the possibility that a registry cleaner program might accidentally remove something that you do need.

Windows already comes with a pretty good disk cleanup tool. Just type Disk Cleanup into your search box and click on the results.

This box will appear. If you wish to clean up a drive other than the one shown, hit the drop-down error and change the drive. Otherwise, just hit OK.

Disk cleaner will scan the disk. This shouldn’t take long.

The results will show you how much space can be freed up. In my case, quite a lot.


You can scroll down and look at your clean-up options. Tick the box next to the items you want to delete. If you aren’t sure what they are, you can select View files.  Once you’ve selected the files you want to delete, choose OK.
