My sister is beginning to use computer/windows XP and has got internet connection. This is her home PC.Now she has many issues involving using it, installing anti-virus and other software, some or the other issues. and it's difficult for me to tell her over phone how to fix it, understand the error messages etc etc. Since she has decently fast internet connection, I am wondering how many ways are there to achieve that I can do remote desktop on her machine from my machine and fix up her system, when she has any issues.
My system also runs windows XP.
Any 3rd party remote desktop client/server software I can install on my machine and guide her to install on her machine and from then on take control of her system, whenever I want.
Ideally, I am looking for something simple lightweight, basic user interface,which doesn't depend on how she connects to internet and how I connect to internet, windows version, even OS so are there solutions where I can provide support from my Mac as well..whereas she doesn't have to change a thing on her machine..
