How To Disable The Startup Delay In Windows 10

Did you know that Microsoft has inculcated a 10-second startup delay by default in the Windows 10 operating system? This means that there is a 10-second gap between initiating your startup apps and complete loading of Windows services. This startup delay has been purposefully designed to allow the operating system to load all essential services before any third-party programs or non-essential processes start to execute. Microsoft believes that this will enable all apps and services to run smoothly and enhance the Windows 10 machine’s performance.

However, if you have some essential programs and apps that you need to start up with when the operating systems boot up, you can eliminate this 10-second startup delay. This is done through a change in registry values, also known as a registry hack, which enables the user to reduce or disable the delay. The Windows service automatic delayed start then will reflect on all apps as the changes did are on system-level and not app-specific.

Note: If you reduce or eliminate the startup delay, then the difference between boot time will be best observed on computers having Solid State Drives rather than hard disk drives. This is because SSD can load programs faster than a standard hard drive in any given situation.

The Final Word On How To Disable The Startup Delay In Windows 10?

Once you set the time to zero, there will be no startup delay on your computer. However, the above steps can also be used for increasing the startup delay from 10 seconds to more if required. A delay of more than 10 seconds is recommended in kiosk machines where only a single program will be auto-initiated when the machine turn on. It is essential to allow Windows 10 to run all services and processes before any application is launched. Always remember to take a backup of the registry first before making any changes.
