Asus Ai Suite II -is it OK to change Scheduled Start to Windows Start

BASIC INFO
I have Windows Ultimate (x64).
I use the Asus Suite II supplied with my Asus Asus P8Z68-V Pro Gen3 Motherboard (which I like for fan and temperature monitoring)

PROBLEM
Ai Suite II always loads BUT "on screen" it is messy during loading because a seemingly AI Suite bar sized white artefact appears top left of screen for 10- 20 seconds before disappearing when the AI suite icon appears in the notification tray. Sometimes a white square also appears temporarily.

TEST OBSERVATIONS
I have noted that if I exit Ai Suite II and reload via the Asus AI suite supplied Shortcut I never get these artefacts AND the suite loads instantaneously (I note however Asus uses AI Suite II.exe via the shortcut
but via the Asus installed Task Schedule it open via "AsRoutineController.exe -open"

I have also tried unloading AI Suite II and AsRoutineController.exe and loading AsRoutineController.exe and it too loads cleanly and almost instantaneously.

I note Asus loads 3 apps via Task Scheduler names:
Asus AI Suite II Execute
Asus DigiVRM Help
USB 3.0 Boost Service"

MY QUESTIONS.
Please can anybody advise me.
1) Why does Asus use the Task scheduler instead of loading via the normal Windows Startup procedures?
2) Could it be so each can be easily disabled if required) and is that the ONLY reason?
3) what is the -open switch in the command line?

IMPORTANT QUESTION
4) Is there ANY good reason why I should not disable the AI Suite II in the Task Scheduler and add it the the Normal Windows Startup applications
I use the Free version of Startup Delayer as it has served me wonderfully with my current Win 7 O/S (and my previous XP) in ensuring all desired Notification Tray Icons display EVERY time).


Today I PROVISIONALLY made the change and AI Suite II opens cleanly (as other Startup apps) without temporary white artefacts and with no noted side effects so far.
I am nervous however, to make it permanent without advice from knowledgeable Seven Forums members on this subject

Many thanks for reading

There should be no problem, as you should be able to change it back. Make a restore point before you proceed.
