...
1.
Choose Start Settings Control Panel Add or Remove Programs.
A list of the installed applications appears.
2.
Select SAP GUI 7.10.
3.
Choose Remove.
4.
Choose Next.
Result
SAP GUI for Windows 7.10 is uninstalled and a log file is generated.
To perform silent, unattended uninstallation, enter the following commands:
NWSAPSetup.exe /Product=”<product name>” /Silent /Uninstall for uninstalling a certain product, for example SAPGUI710
NWSAPSetup.exe /all /Silent /Uninstall for uninstalling all SAP components installed by SAPSetup without having to call specific command-lines for specific products
You find more information on this in section 5.5 Command Line Parameters.
I found this on the SAP website pertaining to SAP GUI frontend version 7.10 for Windows.
They also have information in regards to the SAP GUI for Java but I was unable to find any "uninstallation" information.
Hope this helps,
