If I don't want to deal with installation, my last resort is Teamviewer. I can give them a link to my site that downloads a single executable file that runs without installation. They give me a code and a password that I enter and in no time we're connected. Strangely, it's the fastest method I've used.


There are people suggesting alternatives to the programs that have been mentioned. They're all solutions that DO work, but that I'd never in a million years want to use as a one-off support tool. Sure, if it's someone you support all the time (like a parent), and you're able to set it up in advance, that's great, use whatever you have available. But if it's uncle Steve who has one question, I'd use something like Teamviewer or LogMeIn.
