Hi HNI have a grandma that uses her computer for two things: Skype and checking emails.As her age progresses her ability to use the PC degrades, she forgets how to do things etc. I have a remote desktop so I can help if I can connect. Which is the biggest hurdle as she somehow often turns the laptop's airplane mode.She's on Windows now as that's the OS she's most familiar with (I forced the Win10 to somehow look like WinXP). I am fine with switching to Linux if there is some distro that will allow me to do what I want.So what I am interested in:- preventing her to turn on airplane mode- preventing her to launch anything apart from Skype and Firefox- block any updates which confuse her greatly- keeping the remote desktop runningI expect a recommendation to buy her tablet but she will freak out "learning" something new. Kiosk mode sounds interesting but it usually locks down to single app and I need her to switch between two.I will be grateful for any tips
