A dell laptop user in my work (delivered in full vista 32 bit), I installed this OS to improve reliability and performance. The contract is completed. My 4 GB RAM are finally operated, Outlook opens faster, and the computer is generally more responsive. Installation is simple and easy, but still requires access to specialized pages and forums to ensure that nothing is overlooked. However, the installation of the virtual machine for XP is less obvious; pity that the product does not come with XP pre-installed. It will be interesting to see if these performances are maintained over time.
