As we are sure you have noticed, Windows 8 has not been the big hit Microsoft was hoping it would be. Even the Windows 8.1 update didn’t seem to help things much. Most PC users like the interface of Windows 7 rather than the tablet interface of Windows 8.
For some reason Microsoft skipped Windows 9 for some reason and has released a preview version of Windows 10 that consumers can download and try out. So far Windows 10 appears to be a combination of Windows 7 and Windows 8 offering the Windows 7 start menu and the Windows 8 look and feel and applications. It appears that Microsoft has listened to the complaints about Windows 8 and gone back to their roots at least somewhat.
To push Windows 10 to the masses Microsoft will be offering it as a free upgrade to users of Windows 7 and 8 up to a year after it’s released. Once you upgraded it will be yours to use for the life of the device you install it on and this will include upgrades, patches and enhancements. Microsoft is calling this “Windows as a service”. It doesn’t appear that this free Windows 10 will be available as a download so you can do a fresh install but only as an upgrade. So if you want a clean installation you will most likely have to do a fresh install of Windows 7 or Windows 8 and then do the upgrade.
