Hi TodBilly !
I thought about installing Windows 10, and read a couple of articles reviewing Windows 10... and to be honest, although its a fast system, there are other major concerns for me which the most important is privacy issue. Windows 10 sends a lot of information out to Microsoft. It tracks and shares the websites you visit, the purchases you make, the places you go, the words you type and much more.
For example, even with Cortana and searching the Web from the Start menu disabled, opening Start and typing will send a request to Bing to request a file called threshold.appcache which appears to contain some Cortana information, even though Cortana is disabled.
Let me quote a paragraph of the article that I came across that really sounds disturbing regarding privacy issues. "Windows 10 will periodically send data to a Microsoft server named SSW LIVE COM This server seems to be used for OneDrive and some other Microsoft services. Windows 10 seems to transmit information to the server even when OneDrive is disabled and logins are using a local account that isn't connected to a Microsoft Account. The exact nature of the information being sent isn't clear—it appears to be referencing telemetry settings—and again, it's not clear why any data is being sent at all. We disabled telemetry on our test machine using group policies"
And one last quote which is a huge one: "We've asked Microsoft if there is any way to disable this additional communication or information about what its purpose is. We were told "As part of delivering Windows 10 as a service, updates may be delivered to provide ongoing new features to Bing search, such as new visual layouts, styles and search code. No query or search usage data is sent to Microsoft, in accordance with the customer's chosen privacy settings. This also applies to searching offline for items such as apps, files and settings on the device." This is consistent with what we saw (there is no query or search data transmitted), but also likely to run counter to most people's expectations; if Web searching and Cortana are disabled, we suspect that the inference that most people would make is that searching the Start menu wouldn't hit the Internet at all. But it does. The traffic could be innocuous, but the inclusion of a machine ID gives it a suspicious appearance."
Secondly, I don't like not having the option to choose what update I would like to install or not. Windows 10 automatically installs all updates, even if they don't pertain to you. This is a big disadvantage, because as we saw a couple of months ago, there were several updates that crashed users computers and users had problems logging into the system. In Windows 7, I had more control over what I wanted and more options that gave me a free will.
Maybe I am paranoid, but the above that I mentioned is a need for concern.
