本文在 SAPGUI 7.50 Patch8 测试通过，理论上适用于 SAPGUI 7.20 及以上版本

本文参考自Note https://launchpad.support.sap.com/#/notes/2450698 ，

通过设置如下两个注册表项，用来修改SAPGUI的默认文件下载路径：

The default path can be changed by setting below registry.
[HKEY_LOCAL_MACHINE\Software\SAP\SAP Shared] on 32bit operating systems
[HKEY_LOCAL_MACHINE\Software\Wow6432Node\SAP\SAP Shared] on 64bit operating systems
Key: SapWorkDir
Type: Expandable String Value
Value: The path you want to change
Please also check note 1442303 for more detail information.
Section：Files downloaded by the user

各位可以在 使用 Installation Server 生成SAPGUI安装包时，将这些注册表配置好

 

也可以使用如下的批处理，在SAPGUI安装完成后，将默认路径修改为桌面

复制保存到文本文件中，并将文件后缀由 txt 改为bat即可使用

@ECHO OFF
setlocal EnableDelayedExpansion
