While reading great news and improvements about the Windows 10 Fall Creators Update (1709), it might be useful to find out if the update is already installed or not.
For finding out your current Windows Version open Windows Search and enter About. Hit Enter.
Another option is using PowerShell. Copy the following command in your PowerShell Session and hit Enter.
Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' -Name ReleaseID | Select-Object ReleaseID
It should show 1709 (Fall Creators Update).
If not, be patient. The Microsoft Update Services are only available during the day, not at night. (American Time Zone) 😆
For adminstrators, the most important and interesting thing might be the improvements of Windows Defender. Detailed informations can be found in the Microsoft Security Blog:
