Attempting to install WSUS on server 2012 and then reinstall it.
The initial install went fine:
1/ Prepare security on directories: [Network Service] needs RWX on [%windir%\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files] and [%windir%\Temp] and [D:\WSUS] folders
2/ Either select [WIndows Server Update Services] role from the GUI or in an elevated Powershell:
Install-WindowsFeature -Name UpdateServices -IncludeManagementTools
3/ Launch postinstallation tasks through the GUI or Powershell command below. NOTE: if this is a reinstall then be sure to delete the previous database [SUSDB] from [C:\Windows\WID\Data]
C:\Program Files\Update Services\Tools\wsusutil.exe postinstall CONTENT_DIR=D:\WSUS
