I'm looking at buying a new laptop and I am not tech savvy at all but I've always used ESET products. The laptop I am looking at buying says it comes with Windows 10 in S Mode, and I noticed some of the reviews mentioned they weren't able to install security software because of this. Does anyone know if this is the case, or what I would need to do to install ESET software on Windows 10 in S Mode? Thank you!
