haw can get factory setting for my asus
If it’s not an old model then you have a recovery partition, so with Asus you shut down your computer. After you turn it back on hit the F9 key right after you release the power button.
Re-Install windows by getting the correct iso (make sure it is untouched, no crack or piracy) and putting it on a usb with rufus.akeo.ie and then boot from that usb by pressing esc repeatedly while booting and selecting it. Delete all partitions when installing windows and let it create the necessary system partitions again.
