I’ve just spent three days talking to Microsoft “Technical Support”… often called “HELPLESS desk,” trying to activate Windows 10 Pro. Why? Because late last year, we upgraded from Windows 10 Home by using the “Microsoft Store” application in Windows. HUGE mistake! Why? Because when you pay for licenses through the Microsoft Store, they apply the digital license to your Microsoft account – but you do NOT get an actual product key… which means, if you have any problem, you have to spend HOURS on the phone with helpless desk, going around and around, talking to someone who isn’t as smart as you are, and having them walk through the same ‘trouble shooting’ steps that the previous four helpless desk people have already gone through.
So again, NEVER buy “digital licenses” from Microsoft, that are attached to your “Microsoft account” – they do NOT give you a product key, and if you have a problem, you’ll be spending a lot of time on the phone.
