You can take control of the faulty computer remotely to fix the issue or even show someone else how to navigate similar problems in the future-all as if you were sitting right in front of the device. In that second scenario, remote access is useful for diagnosing and fixing computer problems, like an application that won’t load or even a hardware driver that isn’t working.

Perhaps more importantly, remote access software also lets you take control of someone else's computer when they need help. Your entire desktop is right there, in a window on another device that you have at hand, and you can take control of your computer as though you’re sitting in front of it. Whether you need to quickly check something or grab a locally-saved file, you can. Remote access software makes everything on your computer available to you anywhere you go.
