Terrific. Microsoft is offering a offering me a free upgrade to Windows 10. After reading some wonderful reviews and other than having a DVD player (that costs $14.95) after you install, I found nothing negative about the installation. So I went ahead and gave it a try.
Everything looks great except my Wacom tablet does not work. Yes, my third arm is disabled. Eventhough the driver says it supports Windows 10, it is not recognized in my computer. Calls to Wacom at this time go unanswered mainly because they are swamped with other callers with the same problem.
Now I have to wait for a patch which could be days, weeks, months? Maybe I should just paint on canvas while I wait.
