It is possible to create a shortcut to offer remote assistance in Windows 7 (and XP) using Microsoft Remote Assistance. To create an Offer Remote Assistance shortcut in Windows 7:
- Right click the desktop
- Click New -> Shortcut
- Type %windir%\system32\msra.exe /offerra
- Click Next
This will then create a shortcut to offer remote access, which, when launched will ask you for a computer that you want to offer remote assistance to.
