Windows 11 intentionally postpones programs that launch automatically after login, preventing multiple apps from competing for processor and disk resources simultaneously and causing lag when the desktop loads. According to Microsoft documentation, the system does not guarantee that programs in the "Run" registry key will start immediately, and programs in both the "Run" key and the Startup folder may be delayed. Microsoft engineers have previously explained that launching a large number of apps at once can slow down the computer and may even temporarily prevent users from opening the Start menu.
