I have an Acer Aspire 5920 laptop PC running Microsoft Windows Vista Home Premium Service Pack 2. The PC has a usable hard drive capacity of 105 GB with 54.85 GB of free space. I would like to know to which version of Microsoft Windows I could upgrade because Vista is no longer supported. I am not the most experienced IT person so I would also like to know how to obtain a newer version of Windows, e.g. possibly download it, and how to install it. Thanks!
