In which order are startup programs loaded?
Are Windows 10 startup programs initiated in a specific sequence, such as alphabetical or CPU impact order, or are they all initiated simultaneously?
Are there special cases in which programs are given preference from others, such as Windows Defender loading first for security purposes?

The order is unspecified (except defined by dependence - for example, none programs can start from HKCU/Soft/MS/Win/CurVer/Run or from Autostart menu folder until explorer.exe is started). And no preferences.

Security software often includes system drivers which are loaded before regular applications. It's a broad field so you likely would need to be more specific. What's the order of Windows startup on StackOverflow might be interesting. The part about the logon phase especially.

Good answer. I also want to note that some services can have a delayed start to ensure other services start first (hopefully), or to lessen startup time impact. With so many services and applications starting, there completion times can vary heavily under load. And to address the OPs question, Windows Defender is a service, the application seen in the task tray loads later.
