No, Windows 8 should preserve all of your files and settings in most cases. I%26#8217;ve performed a good dozen upgrades or so since Windows 8 was released to manitacfurung, and I haven%26#8217;t had a single problem. Of course, the big factor is which OS you%26#8217;re currently running. Windows 8 supports upgrades from more recent versions of Windows, but if you want to upgrade from XP, for example, you will need to re-install your programs. I%26#8217;d be happy to provide you with more information. I just need more details about your setup.
