I've successfully converted two W8.1 machines to W10, which I like a lot.
After conversion, one of the W8.1 machines was unable to detect a particular app, Ad-Aware Antivirus. By first uninstalling this app and then re-installing it, I was able to get W10 to recognize it.
I am now planning to convert a workhorse W7 machine to W10. But the W7 machine really is a workhorse and really is fundamental to my work.
Is there any way of pre-testing the W7 machine so I can find out what apps W10 is likely to failure to recognize?
