In the beginning Windows' registry consisted of two files totalling around 5mb in size. Today it consists of at least 12 files with the Software file itself being 30mb or bigger in size. As the size of the registry has exploded, so has the trash and clutter in it. It may seem like a daunting task, but cleaning the registry properly can fix system problems, speed your computer up, and make it run more efficiently.
I have spent many years developing and refining thousands of procedures to do just that. I could share these methods of hunting down the trash with you and let you find them and delete them by hand, but if you were to sit down at your computer right now and work nonstop, you would still be busy with them a week from now when the next issue of Ray's Computer Tips arrives. By then your registry would have new clutter and you would have to start all over again.
To make registry cleaning easier on everyone, I wrote a program called RegVac Registry Cleaner (http://regvac.com/regvac.htm) to perform those procedures. It has been so successful that several companies have asked me to model their registry cleaners after RegVac and even more have copied processes that first debutted in RegVac.
The first place RegVac cleans is the HKEY_CLASSES_ROOT section (the Classes Vac in RegVac does this). This section contains settings for the classes of Windows. Think of a huge box full of snakes and you will get an idea of how complicated and interwoven it is. It is so complicated that many registry cleaners bypass it or simply perform surface scans of it. RegVac uses over a hundred processes to follow each tentacle of each class deep into this area and make sure that they abide by the rules.
Next RegVac validates the entries in 22 lists with 7 different methods (the FilesList Vac does this). This is a minor part of RegVac but the bulk of most other registry cleaners even though they usually do not clean all 22 lists.
Another part of RegVac, the Software Vac, which is unique to RegVac, finds old software sections in the registry and provides a way to remove that software's entire branch. Other registry cleaners only remove a few entries in this area often leaving huge portions of the registry that do nothing but take up space and get in the way.
Even more trash can be discovered in hundreds of stashes used to store data you will never use. Most registry cleaners do not even touch these. The Stash Vac lists these stashes and lets you go through and select which ones to empty out. Please use caution when using the Stash Vac because some of the items listed there may be important. For example, one folder in the Stash Vac lists places where data for international keyboards are stored. You probably will never use the data for Bulgarian keyboards, so you can remove it, but if you live in the US you may experience problems after removing the United States 101 keyboard. The items that you can safely remove are usually obvious.
Last but not least, when cleaning the registry, you should look for broken links to files on the computer (this is what the Bad Link Vac does). If a file is referenced in the registry but it does not exist on your hard drive, that is a good indicator that something is wrong. Many programmers start out writing a registry cleaner thinking all it has to do is check for these broken links and remove them. In fact, that is all many registry cleaners do.
Even though that is all they do, they often don't do it correctly. If you check the results of such scans, you will find out that many of the broken links are really good links. I spent several months refining this part of RegVac so that as far as I know it is 100% accurate. Despite this, please realize that some software enter broken links in the registry and require them to be there in order for them to run. RegVac skips the ones it knows about, but you still need to be careful with this part of RegVac.
RegVac has six more tools that clean even more areas: the Add/Remove Editor, the System Config Utility, the OpenWith Editor, the AutoComplete Editor, the Junk Keys Editor, and Registry Backup, Pack, and Restore.

How to clean your Mother Board
If you have not done the inspection mentioned in the previous article - How to Clean your Case, now is the time to do so. Look at the blades of the fan in the back of the computer. Also look at any vents. Is there clusters of dust there? Is there grime caked on to it? If so, the inside needs to be cleaned. If the fan blades are clean but it has been several years since you have cleaned the motherboard or if the computer is around cigarette smoke, it probably should be cleaned anyway. Dust and particles in the air (like cigarette smoke) can build up on the circuitry of the motherboard and cause it to heat up and/or corrode.
The first thing that you need to do is unplug your computer. Then open up the case to get access to the motherboard. Cases open differently. If you don't know how to open your case, look on the back of your computer along the edge for some screws. These screws may hold on side panels or an upside down U shaped panel that covers the sides and top. Removing the screws will allow you to take off the cover. Other cases have the screws on the front of the computer. To get access to these screws, you must first remove the front panel by pressing a hidden latch. The cover is there to give easy access to the inside of your computer, so if you look hard enough, you should be able to figure out how to remove it.
Remember that if you touch anything on the motherboard, you should be grounded by either touching the metal frame of the computer with your other hand or by wearing a special grounding device.
The goal of cleaning the motherboard is to remove all dust and debris from the motherboard and all components inside of the case. This can be done using one of three methods.
The preferred method is to use a can of compressed air to blow it out. Always hold the can in an up-right position to prevent the propellent chemicals which can damage or corrode components from coming out. Dust and dirt should be blown away from the motherboard and out of the case.
Another way to remove dust is to use a vacuum. The common advice is to only use a battery operated vacuum because an AC powered vacuum causes static and static can ruin the motherboard. I have used an AC powered vacuum (before I knew that it was not recommended) to clean my motherboard many times and it has never caused any problems, but I may have just been lucky. When using the vacuum, keep the nozzle a couple of inches away from the motherboard or any other components so that it does not come in contact with them and so that any small parts are not sucked into the vacuum.
If you do not have a can of compressed air or a vacuum, you can use a dry cloth and brush to clean the motherboard. Be careful not to dislodge or break anything using this method.
While cleaning the motherboard, be careful not to unplug any cables or connections or to dislodge any loose components, such as, jumpers.
Methodically clean the whole inside of the case going over all of the motherboard from one end to the other and all other components. Don't forget to clean the fans and heat sinks. Do not open up the power supply box or stick anything in it beyond the fan. If you do, you could get a shocking surprise and ruin your computer.
If your computer does not work when you put it back together, something was obviously dislodged during the cleaning. Open the case back up and push all connections and cards into their slots. Look for anything that may have become disconnected.
Cleaning the motherboard is probably the most dangerous form of cleaning but it is necessary to prevent an early death of your computer.
