Global variables within IIS Express

Question

I've just installed IIS Express, can anyone tell me where it gets the settings for the following variables?

%IIS_BIN%
%IIS_USER_HOME%
%IIS_SITES_HOME%
%SYSTEMDRIVE%

Thanks

Answer 1

To "change" the paths for the %IIS_USER_HOME% and %IIS_SITES_HOME% values, please see my explanation here.

Answer 2

%IIS_USER_HOME% - The IIS Express home directory for the user
%IIS_SITES_HOME% - The default home directory for sites
%IIS_BIN% - The location of the IIS Express binaries
%SYSTEMDRIVE% - The drive letter of %IIS_BIN%

Answer 3

The following three environment variables are set by iisexpress.exe during the process startup.

• %IIS_BIN% - refers to IIS Express installation folder (%PROGRAMFILES%\IIS Express)
• %IIS_USER_HOME% - %USERPROFILE%\Documents\IISExpress
• %IIS_SITES_HOME% - %USERPROFILE%\Documents\My Web Sites

%SYSTEMDRIVE% - is a standard windows system environment variable
