I have been using this for a while across some of my devices and found it works very well.
Teamviewer basically allows one person to access another persons PC via the internet and aids in giving support to them. The one giving support will need the full software but the ones receiving it can use the small, easy to use access only module. Both are free for home use. I have attached links here for you to use.
This is for the Full version
and this is for the access only module
Give them a try, you never know when you will need something like this.
