Issue: After configuring Desktop Image, Windows settings such as theme, icon placement, taskbar settings, etc. are not applied to the hosts created from the Desktop Image.
The sysprep process Nerdio Manager executes will remove local profiles from the template before running the generalize command - we do this to help avoid issues with appxpackages or other installed apps from causing the sysprep process to stall, and to minimize the amount of remediation time spent troubleshooting sysprep. The local profile that's customized is also cleared.
What most of our customers have found great success is with customizing the user's default experience using group policy - things like default themes / backgrounds, desktop icons, task bar and start menu layouts, application preferences, etc can all be setup and pushed to the hosts with GPOs. For example, the start menu tiles can be customized and then saved using Export-StartLayout PowerShell command, and then setup in Group Policy to apply the matching Import-StartLayout command once during the initial login. There's other options like modifying the C:\Users\Default user profile, but know that modifying the registry and start menu / taskbar preferences can be a little tricky - although this is a very easy way to setup initial shortcuts and folders.
