The Run startup scripts asynchronously machine setting should be configured correctly. Lets the system run startup scripts simultaneously. Startup scripts are batch files that run before the user is invited to log on. By default, the system waits for each startup script to complete before it runs the next startup script. If you enable this setting, the system does not coordinate the running of startup scripts. As a result, startup scripts can run simultaneously. If you disable this setting or do not configure it, a startup cannot run until the previous script is complete. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Scripts\Run startup scripts asynchronously (2) KEY: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\RunStartupScriptSync
