我自己用的740补丁版本也较低，好像是4-10013011，之后没敢再打，再打也就不能用快捷登录了。上次打完补丁不能用，我是卸载然后清理了很多东西后再重装的。
今天偶然看到这么一个帖子，提到了一种解决办法：
146173 - SAPShortcut: Saving password in SAPShortcut - not recommended
The following is valid as of patch level 1 of SAP GUI for Windows 7.40:
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.
如果已经装了nwbc,直接卸载一般无效,但也没必要把740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
