On July 29, 2016 (29 Jul 2016, 20160729) Microsoft will end it's free upgrade offer from Windows 7/8/8.1 to Windows 10 - that is only 39 days from now! That's 944 hours, 39 days, or 5 weeks!!! Windows 10 has come a long way, and there are tools to lock down the telemetry and other vulnerabilities inherent in Windows 10. As an IT guy I feel now is a good time to do the upgrade if you have been hesitant/reluctant to do so This is my first time warning and update post, my next version of the post will have more good info in it. Here is one good piece of info: http://getblackbird.net/ this is an awesome tool to lock down Windows (especially 10) the way it should be. I am scrambling to install Windows 7 on all the computers I own that will run Windows 7 or 10 so I can get my free upgrades.
