Many a times our PC just crashes and we are left with nothing but to clean install it with Windows 10 ISO. After installing it, then you may find that the drivers are not present and you forgot to download them as well. (Most of the time, the network drivers install automatically if every Windows 10 service is running as they should. This guide is for exceptional cases.) Here's a handy guide for all Acer users that will allow you to install your drivers without having to download most essential of them. There's a hidden OEM folder in C Drive of all Acer laptops. you can use that to install your network drivers, Predator Sense, Office Trial (if included), and some other things like the Firefox tuned for Acer.
I used my Predator Helios 300 (G3-572) for the following pictures of my OEM folder.
1. Go to C Drive and on View tab, select the check box saying Hidden Items. You will notice new folders coming into view.

2. Go to the OEM -> Preload folder.

3. For the apps that came with your Predator, go to APP folder and install what you want. (Not everything will be available though, only the necessary ones.) Here's what my APP folder shows:

4. For the essential drivers (i.e. Wi-Fi and Ethernet), go to Autorun -> DRV and install the ones provided there. For me, it contains Bluetooth, Wi-Fi and LAN drivers.

Install them and now you can download the other drivers using your preferred internet connection from support site. Predator Sense can be found in Preload -> Autorun -> APP.
Some extra OEM settings are also there but I couldn't figure out how to use them. You may tinker with them only if you really need to.
Hope this guide helps whenever you require it 😁!
