Although they are definitely the minority, I do have a few clients that are still on Windows Vista.. the thing is, these computers are performing well and most certainly meet all the necessary requirements to run the latest Windows 10 operating system. They may not be eligible for the 'free upgrade' by performing the "normal upgrade' process however that doesn't mean it can't be done.. need more information or would like to get me to get this done for you, simply contact me and I can help with the diagnosis and upgrade if necessary.
