Today, Microsoft has finally announced when it will be rolling out the newest version of Windows: July 29th will be the big day. To prepare for the date, Microsoft is sending out notifications to users of older versions prompting them to reserve their free copy.
The reservation process is simply a way to opt-in to the free upgrade ahead of time. Once it becomes available, if you've opted-in, the update will automatically download and install for free. Microsoft hasn't yet explained any details about how, when, or if the company will start charging for Windows, however it seems likely that you'll still have a chance to get the free upgrade if you don't reserve it now. However, if you know you'll be upgrading, it's a handy way to expedite the process once July 29th rolls around. If you're still on the fence about whether or not you want to install Windows 10, here's everything you need to know.
