Windows 8.1 is running on my Mac in a virtual machine. I attempted to “reserve my free upgrade” when the program was announced a few months ago. I installed the hundreds of updates, restarted numerous times, never saw the icon in the system tray, and gave up.
Tonight, I try again. The VM had already gone through all the updates and a few more restarts before I found a support page with a troubleshooting app that thinks there is an installed update that has never run. Having uninstalled it, it’s time to try one last time before giving up again.
