a) telemetry

b) I'm worried my fairly nicely working Win7 environment will not work so well after updating to 10, as much as I want to get current with some genuinely useful features.

I'm generally a Microsoft "fan", but this is one of the many reasons I hate on them as much as Linux fans.

I never "upgrade" from one Windows OS to another. Always done a clean install. I postponed the upgrade because it's literally a couple of days' time project for me to get my dev environment up to speed. I also planned to purchase a new SSD before doing the new install (kill two birds with a single stone.)

Unfortunatelh I've been so busy with project deadlines that I haven't had a weekend I could dedicate to the new install and set up.

I guess I'm forced to now.
