Remote desktop is an operating system feature that allows the user to connect to a computer in another location, see that computer's desktop and interact with it as if it were local.
You can access the Remote Desktop program by going to Start and typing in 'remote'. The top result should be 'Remote Desktop Connection'.
Should you wish to connect to your work PC, you will need to be connected to the company network and know the PC name e.g. EC01 (there will be a sticker on top of your PC with the EC number). If you are outside of the company network, i.e. working from home, you must start your VPN connection before using Remote Desktop. Please click here for guides on using the VPN.
You may wish to use Remote Desktop to use some software you don't have on your current computer or to access some documents you've not saved on network drives.
