Remote Assistance allows you – or someone you trust – access the computer remotely. It's a useful way to let a family member or trusted technician diagnose a problem you have with your computer without having to be there. When you are not using remote assistance, you may want to disable this potentially vulnerable service.
How to disable Remote Assistance
Open the control panel by clicking the Start menu, typing "Control Panel", and then clicking the program's icon.
Click "System and Security" in the list of settings.
Next, click "System".
On the list of settings on the left, click "Remote Settings" to open the Remote Assistance Settings window.
Finally, uncheck the box next to "Allow dial-up connections to this computer" and then click "OK".
It is all there is to turn off Windows Remote Assistance. The next time you need remote help from a friend or family, be sure to enable this service before you begin.
