No I am not a MS employee, or even a big fan of MS. I have Apple products, and multiple Linux servers. Windows Server absolutely sucks but I'll take Windows 10 over 7, or 8 any day because:
Windows 8 just plain sucked
Windows 10 has a USABLE start menu with an EXCEPTIONAL way to setup shortcuts to the apps I use all the time.
Windows 10 makes it oh so easy to get to the control panel items you actually use
Windows 10 starts faster and shuts down quicker
Windows 10 plays nice with my Office 365
Windows 10 replicates the task bar on all monitors
I could care less that MS is watching. My company does web dev, so I am a bit of an expert on how your web activities are tracked, if you want privacy get a flip phone, disconnect the internet service, watch OTA HDTV, and use all cash...
