I use Ivan RF to keep my laptop drivers and programs up to date. Doing this requires you know what is on your laptop, so you can update.
The Ivan RF website uses ASUS sources for their drivers and programs. Look at the download links that are generated. Call it a third-party site if you want but Ivan RF is using ASUS downloads from many laptop models.
Personally my G752VSK is updated with many drivers and programs from the G703 models. I run version 2.5.10 ROG Gaming Center on my laptop that came with version 2.1.5. I have no issues at all.
You must be careful, apply drivers and/or programs, one at a time. If the newer driver and/or program doesn't work, you must be able to revert back to your original. Personally I only had issues with the Realtek audio drivers from ASUS.
Of all the original drivers and programs that came with my laptop, I have updated all but three from the Ivan RF website.
We'll I could teach you how to update your drivers and programs using those provided by the Ivan RF site (ASUS), but that would require you to learn something new, which unfortunately is not something you wish to do.
Have a nice life!
