Windows 8.1 Preview upgrade process gets detailed
The upgrade process from Windows 8 to Windows 8.1 has appeared on the web today, revealing everything the system does to install the new Windows 8.1 upgrade from the Windows Store. The upgrade process will require the user to download a separate update from the Windows 8.1 Preview download page. This separate update will get everything in motion for your system to download the Preview from the Store.
After this separate update is installed, you will get a notification across your screen prompting you to check out the new Windows 8.1 Preview. From there you will be able to install the preview. It will download just like any normal app, allowing you to cancel the install at any point.
While the update is downloading, Windows is preparing the system for upgrade behind the scenes. When the download is complete, Windows will want to restart to begin applying the update. After this restart, Windows will display the usual License Agreement and OOBE (Out-of-box-experience) which will allow you to setup Windows 8.1.
So there you have it, the upgrade process is fairly simple. Of course, if you’d rather install the update via the traditional method, Microsoft will be offering ISO’s for those who want to clean install or dual-boot their systems.Further reading: Microsoft, Windows 8, Windows 8.1
