Thanks, but unless Windows 10 gets a WindowsXP Mode, such as is available in Windows 7 Pro, I will be sticking with Win7 (legacy hardware and software issues and Win 10's ''compatibility mode'' is next to worthless for my purposes). But, it does seem that I can continue to upgrade until or unless I have problems, at which point I'll just uninstall the most recent version and reinstall the last working one. Thanks again!
