I have done most of them now.
Out of caution I have left the two most important pc's till last.
The very most important pc is a Win7 unit running Reckon accounting software.
I have had a few Win10 upgrades that (without warning) removed some programs even though the pre-upgrade status said there were no incompatible apps.
Has anyone done a Win10 upgrade on a pc with Reckon installed and was still smiling afterwards?
