public VS AutopilotBranding

Try these https://github.com/andrew-s-taylor/public/tree/main/Install-Scripts

I use powershell and dism https://github.com/andrew-s-taylor/public/blob/main/Install-Scripts/WingetOffline/Source/installwinget.ps1 That's for winget which is an MSIX bundle with appx dependancies

It's been a while since I've used this and don't know if it still works, but I used the autopilot branding script to set the background and lockscreen.

It was written for Autopilot but works great for OSD as well. https://github.com/mtniehaus/AutopilotBranding

I would use the Auto Pilot branding script here. https://github.com/mtniehaus/AutopilotBranding it will work outside of Auto Pilot.

If you want to upload a wallpaper to your users but allow them to be able to change it if they would like you could try using this PS Script and deploying it like we have https://github.com/mtniehaus/AutopilotBranding ?

For Time Zone, I believe there are some community scripts that leverage the Location Services to help set the time zone automatically. Take a look at this github repo from Michael Niehaus, the former Project Manager of Intune at Microsoft.

I use this: GitHub - mtniehaus/AutopilotBranding

I had the same thing and Microsoft support told me not to mix win32 apps with line of business apps. In my case I was using the autopilot branding script (https://github.com/mtniehaus/AutopilotBranding) which is a win32 app and the other apps like office are line of business. Basically during the install these different apps interfere with each other. Last time I worked on this was 3-4 months ago so maybe things changed.
