Impersonation Windows 7

[dr_awol]

Im wondering is it possible to impersonate my admin user using nsis? I know the un and pw

do i need to call System.dll, how would i call the appropriate API functions?
sorry if this is a silly question but im new to nsis.

I will be logged in using with a standard user when running the installer

Its this the correct route i should be following?
