Question Windows 10 doesnt let me delete folder

Open "Command Prompt", navigate to your desktop folder, C:\users\<username>\Desktop, and execute "dir /a". Do you see that folder here? If so - "del <foldername> /F /S". If not - that folder appearing on your desktop could be a "public" folder, so check C:\Users\Public instead. Or just right-click on it, "Properties", and see where it's located.
