Windows 10 is out in the wild. If you haven’t already seen, Microsoft has been advertising it to Windows 7 and 8.1 users using a system tray pop-up. This is a free upgrade, and will probably be a good one for Windows 7 and 8 users alike. Microsoft wants to get all recent Windows machines on the same operating system, providing a standardized Windows platform and pushing the “universal apps” offered by the Windows Store. After the mess of Windows 8, Microsoft appears to have come to their senses and Windows 10 is looking pretty solid.
