Vista之后提高权限删除桌面图标

Shortcuts removal fails on Windows Vista Windows Vista and Windows 7 automatically identify installer executables, including NSIS installers, and ask the user permission to run them with elevated privileges. Automatic detection, however, comes with the price of automatic backward compatibility tricks. One of which is automatic relocation of shortcuts created in the Start Menu to the All Users' Start Menu.
To workaround this, use the new RequestExecutionLevel command or create the shortcuts in All Users' folders in the first place, using SetShellVarContext.

RequestExecutionLevel admin #NOTE: You still need to check user rights with UserInfo!
SetShellVarContext all

OutFile vista.exe
Name Vista

RequestExecutionLevel admin #NOTE: You still need to check user rights with UserInfo!

Function .onInit
#TODO: call UserInfo plugin to make sure user is admin
FunctionEnd
