CrossLoop Lets You Fix a Friend or Relative's Computer Remotely
CrossLoop is an extremely simple tool that you can send to that person in need of computer help. You can send them a link to download it (click on the CrossLoop logo up top to download it). Once they download CrossLoop, they then click the "Share" tab and send you (by phone or by e-mail) their Access Code. They click the "Connect" button (under the Share tab) and you click the Connect button under the Access tab. They then have to click the orange Yes button. So, legally, you cannot connect to them without their permission. You get two minutes to connect to their computer once they've clicked on "Connect," and there is a timer that counts down. Once you see their desktop, you can minimize their little timer control panel to get it out of the way.
The How-To Geek wrote up a beautiful tutorial with screenshots on how CrossLoop works from start to finish.
Once you've fixed your friend or relative's computer problem, you can get back to your plans for the evening. Any tool that allows you to do that is gold, at least in my opinion.
