Thinkstock / hudiemm / Getty Images It’s that semi-annual time again when a new Windows 10 feature update is imminent — and when you need to decide whether or not you want to participate in its unpaid beta testing process. Microsoft makes it easy for you to opt into beta testing, but not as easy to opt out. Sure, Microsoft says its Windows Insider program is its beta testing program for new releases of Windows 10, but I honestly consider that more of a mechanism for marketing new features. It’s only when a new Windows 10 feature release is offered up to the public — and begins to run on all of the different hardware that we have out here in Windowsland — that the true testing begins.
