The DelayLockInterval time in Windows 10 is the amount of time after the display turns off before you are required to sign in when you move the mouse, touch the touchpad or touchscreen, click a mouse or touchpad button, or press a key to turn the display back on without the computer going to sleep or hibernate first.
When the display turns off automatically on Windows 10 desktop and laptop type devices, you are not required to sign in by default when you move the mouse, touch the touchpad or touchscreen, click a mouse or touchpad button, or press a key to turn the display back on. You can continue where you left off when the display turns back on without being required to sign in first.
When the display turns off automatically on Windows 10 2-in-1, convertible, Surface, and tablet type devices, you are required to sign in by default when you move the mouse, touch the touchpad or touchscreen, click a mouse or touchpad button, or press a key to turn the display back on. You will be required to dismiss the lock screen, and sign in to Windows 10 before being able to continue where you left off when the display turns back on.
If you have a short turn off display time set and are constantly having to move the mouse, touch the touchpad or touchscreen, click a mouse or touchpad button, or press a key to turn the display back on, it can be a real pain to also be required to sign in each time if you have a short DelayLockInterval time delay.
If you are not required to sign in after the display turns off, you may want to enable and set a specified DelayLockInterval time delay to automatically require sign in for better security.
If you like, you can enable and change or disable this DelayLockInterval time delay depending on what you want for your situation.
