Is it possible to see what someone else is doing on the computer?

Using screen sharing or mirroring software, it is possible to see what someone else is doing on their computer. This type of software is commonly used for troubleshooting, giving presentations and working collaboratively.

Some screen sharing software allows another person to remotely log into and control a computer belonging to someone else. Screen sharing software is available from a large number of companies and may be free, sold for a single payment or for a monthly subscription fee. LogMeIn, Teamviewer, Splashtop, Chrome Remote Desktop, Microsoft Remote Desktop (RDC), Apple Remote Desktop and VNC have all received good reviews. Using screen sharing software that doesn't explicitly ask the user's permission to make a remote connection can be a security risk, as it makes the computer vulnerable to scammers and hackers.
