And here it is: after several months of waiting, a few pirated editions and a preview officially released by Microsoft last June, Windows 8.1 is finalized. Redmond has already distributed it to PC and tablet manufacturers, and has also delivered it to owners of MSDN and TechNet accounts. In reality, this is the version RTM (Ready To Manufacturing), which should experience very few changes by the version available in stores and on Windows Update. Have you already recovered this version by one means or another? Or would you prefer to wait until October 17, when the operating system will be officially available to the average person? In all cases, here is a series of questions and answers that should help you whatever your configuration.

How to take advantage of Windows 8.1?

Microsoft has not yet officially communicated on the minimum configuration of the final Windows 8.1, but the company did so on the preview released last June. Since there is no reason why it should change in such a short time, we can already know the minimum vital to run the new OS: a 1 GHz processor, 1 GB (32 bit) or 2 GB RAM (64 bit), and between 16 GB and 20 GB of space on the hard drive. Without counting a graphics card at least compatible with DirectX 9. Clearly, any PC released in the last ten years can do the trick, with of course, better results in terms of speed and responsiveness on recent hardware. Another point, the update method. On this, Microsoft has been clear: it is possible to migrate from any version of Windows, but the result differs. Since XP and Vista for example, Windows 8.1 erases all data from older versions of the OS (so this is not an update, but a complete reinstallation). It is therefore necessary to back up your personal data first. In Windows 7, on the other hand, we recover our data, but it is necessary to reinstall all the programs. Finally, under Windows 8.0, everything happens as if it were a question of installing a service pack. There is therefore no need to reinstall anything.
