I got a new build going, and will be doing the final transfer of hardware later this week. This also means a new install of Windows. Fortunately, I have a retail license for Windows 7, and the old system will be be useless so I can transfer that over as well as the rest of my software. My question is should I stuck with Windows 7 or move on up to Windows 10? My concerns are about the privacy of my data. I intend to disable a lot, if not all the tracking stuff but I know I need some other stuff to really disable it all. I keep my own backups of stuff using external HDD's and cloud services. I don't care for things like Cortana or system theme settings being synchronized, etc. I will use the mail app, One Drive, and possibly some other built in stuff. I don't want all this stuff going to MS, and I don't want there keylogger running or even installed if possible to remove. I will be using it for College classes and games. EDIT : Changed when I'll be doing the transfer.
