Today is the day! Windows 10 is finally here. Microsoft has began rolling out the Windows 10 upgrade for existing users of Windows 8.1 and Windows 7. The upgrade process is being handled by a reservation system that started a little while ago, which let you tell Microsoft that you intended to upgrade. This was done using the Get Windows 10 (GWX) app that has been in your system-tray. Once you have “reserved” your copy Windows will slowly fetch installation files for Windows 10, and stores them in a temporary location. Once all files and drivers have been downloaded the app notifies you that the upgrade can begin.
The upgrade process is quite seamless, but like an Android or iOS upgrade. Once the upgrade has completed you get the option to customize a few things. GWX may notify you at any time today that the upgrade is ready to begin. If you didn’t reserve your upgrade you can still do so today although you might not get the upgrade right away. With an estimated 350 million installations queued up for the upgrade, it could take anywhere from a few days to weeks to get the upgrade.
If you don’t plan on doing an upgrade you can download the Media Creation Tool from Microsoft and make your own DVD or Flash Drive with the Windows 10 ISO on it.
