Q: How do I turn off factory wallpaper that shows when I connect remotely? It makes the connection really slow.
If it’s on a domain and you are an admin you can use the remote registry.
Otherwise you can suffer through it for one more connection. Open regedit and navigate to the following registry branch:
HKEY_USERS\.DEFAULT\Control Panel\Desktop
Find the Wallpaper key and change it to (none) including the parenthesis.
