If we were to talk about the most successful versions of Microsoft's Windows computer operating system, we would have to say that Windows XP is among the versions preferred by the public. In fact, after many years on the market, it is still a version of Windows that many people prefer to the following ones, and in that case, there are some essential tools or applications that you should not lose sight of.

Such is the case of RockXP, a simple but very functional utility explicitly developed to recover the serial number of Windows XP at the installation time. The truth is that for different reasons, we may not have it. As it is a necessary element to be able to take advantage of the possibilities of this environment, there is nothing better than having an assistant like this one.

Although it is possible to recover the installation key in another way, for example, by inserting the Windows installation disk or viewing the registry, the truth is that RockXP makes this type of procedure incredibly easy. Many novice users, who may not know how to carry out these tasks, will find an almost immediate solution to their needs in this service.

RockXP is a program that will be useful when reinstalling your Windows XP operating system since it does not generate keys for new installations but recovers those of previous installations. If we have lost the CD with the serial number, we do not have to worry about it or waste time searching for it but use this software.

But in addition to this function, which we could say is the basic one of RockXP, we must not lose sight of the fact that it integrates other fascinating complementary functions, such as the ability to save the activation number in the form of a file. Thus, you will never have to look for the installation CD again, and you can even eliminate this tool since you will already know where to find the code in question.

RockXP will also allow you to recover different names and passwords saved in the Secure Storage of Windows, another type of content that can be difficult to obtain again if we do not have this utility. And if you still have doubts about giving it a chance, think that you can generate random passwords from the same program or obtain specific data from your Internet connection.

Beyond all of the above, we also wanted to highlight the general feeling of speed that RockXP has given us, considering that it responds almost immediately to each of the functions we have decided to run. This is not a minor detail, considering that computers running Windows XP often do not have the same power as other, more current ones, so having a fast and light program is a real advantage.

We didn't want to finish our analysis of RockXP without saying that it is not only a free platform but also portable, saving us the always annoying installation process. This is not a minor detail, considering that those users who use several computers during the same day or week will avoid wasting time, which could be very annoying.

As for RockXP's user interface, we must say that, in general terms, we liked it, taking into account that it is simple to see the location of the different functions, which is essential for beginners. In addition, as it is ultimately translated into other languages, this tool is much easier to use, especially in what does not have to do with the basic features.

The main positive issues we have found in this approach to RockXP have to do, for example, with the easy recovery of the Windows XP activation code without requiring installation disks or anything else. But also its random password generator and the fact that it is a portable program give it a particular advantage over other similar programs.

The worst thing about RockXP, and here we are going to be a bit unfair, is that it is not a platform that we can use with other versions of Microsoft's computer operating system because, at times, we would need it. In any case, we must not lose sight of the fact that it is software with almost no weaknesses; on the contrary, it provides many answers.

In conclusion, we must say that RockXP is an almost essential application for any user who currently has a Windows XP computer since it provides crucial information, such as the activation code of the operating system, but also many other additional features that could be useful in emergencies.
