Remotely supporting your computer
Sometimes it is more convenient or otherwise better for us to support you remotely. Maybe you don't want to unplug all the cables from your computer or you're still in your pajamas. Remote technical support allows us to 'take over' your computer over the Internet as if we were sitting in front of it and help you. Sometimes, remote support is not the best option, such as when you're having certain hardware problems, your Internet isn't working, or you (understandably) just want someone on-site.
P.S. Don't let just anyone take over your computer. Remote support scams are all the rage right now.
