But often the user (or client) does not want to reformat their computer for reasons we can’t change, for example, has a management system which the installation is for a single license with a limited time. In that case, you can restore Windows without formatting, using the steps below :
Although this step does not seem right, but you must disable any process that starts with Windows, so they do not interfere with execution of this procedure, because there is often sneak viruses or malwares in your PC.
And to do this, I recommend CCleaner, install and open CCleaner and go to the menu “Tools”, find an option called “Startup, where we will remove all processes that start with Windows.
Once you apply this simple step, restart the computer.
Uninstall unnecessary programs like antivirus, toolbars, and so on
With CCleaner, click on the tab “Uninstall”, now remove the programs which we do not need, such as:
Antivirus: Yes, even this is illogical, you need to do what this guide will explain, we need to uninstall completely to avoid interfere with the process, and let the tool works.
Toolbar: A lot of software installed toolbar makes your PC slow, that’s why I recommend you uninstall them without exception
Clearly, once we have removed a series of unnecessary things, let the computer reboot again to continue to implement the third step, which is the most important, because with it, we will remove viruses, and the things that affect

Clean the Windows registry with Argente Registry Cleaner
In this steps we’re cleaning the windows registry but we can not do as thorough of the Windows registry. This is because the system registry is a database where information is stored that will make changes to your PC, as a key (or “word”), with a structure that I think is quite susceptible.
It is for this reason, it is very important for clean up invalid registry entries, so the operation of the computer is the best. And for this, I highly recommend, for use an application called Argente Registry Cleaner. Is a free program in Spanish. You can download it here.
