Hi Timster:
This is not intended to be a criticism of you or your business. The statistics surrounding your contention that "most users also have no issue" are at best, subjective (mostly provided by people with a vested interest, or by Microsoft itself) and cannot be considered a reliable guideline, being that it is so early after the release of Windows 10.
As I stated in an earlier post, I have not had any problems with upgrades either for myself or clients BUT that is only speaking for a small town where I conduct my business.
Similarly, you may be able to speak for Savanna, GA area, but beyond that you are mostly relying on the opinions of others I would think.
Conversely, there are people who just don't like it, or are frustrated because it made them change from the familiar to the unknown. Those people have a voice as well, and have said so on this forum. Opinions may change over time, but there will always be dropouts and cop-outs.
If it is any consolation to them, I too am 'slipping back to my Windows 7' OS for lots of things.
