SAP给出的答案：The following is valid as of patch level 1 of SAP GUI for Windows 7.50:If you use saplogon.ini/sapmsg.ini, the previous system behavior is still valid. You can continue to allow passwords to be saved in SAPShortcuts, although we of course do not recommend doing so (see above).If you use SAP UI Landscape (in conjunction with SAP NetWeaver Business Client (NWBC); for more information, see the SAP Frontend Installation Guide), the registry value mentioned below no longer has an effect. You cannot use the corresponding maintenance dialogs to save passwords in SAPShortcut files. Furthermore, passwords in existing SAPShortcut files are removed when subsequent saves take place.大概就是：如果已经装了nwbc,直接卸载一般无效,但也没必要把750重装,找到原来的安装包SAP GUI 740\BD_NW_7.0_Presentation_7.40_Comp._1_\PRES1\GUI\WINDOWS\WIN32\SapNwBcSetup.exe,desellect all,uninstall成功,然后重建shortcut即可,效果如下。
