The computer registry can be thought of as similar to an address book that holds hundreds or even thousands of names, addresses and other important data. The windows registry is probably the most critical part of the machine. It is a database, a bit like an address book, the address book has a pack of cards, on the cards are the data entries. Windows uses this information which holds details about hardware and software on your computer to run the system.
It holds information about user preferences. Anything you alter in your system is written to the registry. Editing the registry is not recommended unless you know exactly what you are doing as entering the wrong data can seriously affect the users' PC to a point where it is no longer useable.
The tool used for editing the registry is called Regedit. Older windows versions had a registry editor named regedit.exe. Microsoft did away with that and created a new editor named Regedit32.exe. If you fancy looking at the registry editor, by all means, have a look but DO NOT UNDER ANY CIRCUMSTANCE alter anything! it could result in serious damage to your PC.
To run regedit you have to open up your command prompt which is the heart of the Windows system. This is where the main DOS commands are issued manually by a person or program once executed. For example, if you wanted to get to a file or directory in the Windows graphical user interface, you simply open a file or folder by clicking on it but, in the Microsoft disk operating system (DOS), command lines are issued to do the same such as "cd" which stands for change directory. Type "cmd" without the quotes into the search box and press enter.
To show a list of subkeys you click the little arrow to the left of the root key. Other keys and subkeys can be seen by clicking the folder icon. The values and aspects held in the subkeys are here. All the root keys perform specific functions. The HKEY_CLASSES_ROOT folder defines the class objects.
HKEY_LOCAL_MACHINE contains every piece of information about the machine and the software installed on the computer. Here you can see that on my machine, my default media player is VLC player. So as you can appreciate, the registry is very important but it is also very delicate. Over some time it can become cluttered, even corrupt. If this happens the computer may slow down or may not even work. This is why it is a good idea to maintain it. Cleaning and defragmenting the registry is a very good way to do this. Don't forget to close the editor.
You now have four options. Follow this guide here, Print this page and follow the guide on paper. Follow a video guide ( I am currently updating the videos as the ones shown are from the pervious website layout) Or you could simply load clean my pc onto your mobile and follow from there, don't forget to rotate the phone for a bigger picture.
If you haven't already done so, start up Wisecare by going to your desktop and double clicking the Wisecare icon.
DO NOT PROCEED IF YOU HAVE A SOLID STATE DRIVE! USE THIS OPTION ONLY IF YOU HAVE A HARD DISK DRIVE INSTALLED!
If you are unsure which type of drive you have, Click in the search bar at the bottom left hand of your screen, type "dfrgui" without the quotes and press enter. When the new window has opened, it shows your drive or drives installed on your PC.
If you have more than one drive installed, scroll down the list to find the Windows system drive, it usually has a tiny light blue icon with four dots on it and it is usually the C drive. There you will see the type of drive you have either, a hard disk drive or solid state drive. Click close when done.
DO NOT PROCEED IF YOU HAVE A SOLID STATE DRIVE! USE THIS OPTION ONLY IF YOU HAVE A HARD DISK DRIVE INSTALLED! Go to your desktop and double click the Wisecare icon to start the software. Click YES to accept the option, you now need to select system tune-up from the list of options at the top of the page.
The next step is to defragment and clean up the registry to keep the PC in tip-top condition. You will not be able to use the system until the software has run its' course. Make sure you have enough electricity if you are on a pre-paid meter. I learned a valuable lesson one time when I was defragmenting the registry and the power went off rendering my PC useless. I had to do a complete recovery, also, DO NOT turn the power off when it is running. Be sure that no software is updating that may require a re-start. Click Registry Defrag from the left_hand menu.
Before the software executes the defragmentation of the registry, it needs to analyse it and do its' computations regarding space on the drive to move registry the entries around. when the system has been analysed its' then time to proceed to analyise by click the green button top right.
Now it is time to defragment the registry on your system. The software will firstly create a restore point. This is used just in case something goes wrong, you can always go back and restore the drive to a point before anything went wrong so, make sure the check box to restore point automatically is ticked. When the defragment button is clicked, your system will reboot, just give it some time to work as the process could take a while. Just a reminder, DO NOT CLICK THIS OPTION IF YOU HAVE A SOLID STATE DRIVE! USE THIS OPTION ONLY IF YOU HAVE A HARD DISK DRIVE INSTALLED! again, if you are not sure what type of drive you have, go to the top of the page and read from there. Once your computer has rebooted, your registry should be clear of clutter, it will be all nice and neat in memory which means a faster and more efficient computer.
