i've just switched to Windows 7 RTM and installed ASP.NET and IIS
i seem to get the error HTTP Error 500.23 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode

This error 500.23 translates to -
An ASP.NET httpHandlers configuration does not apply in Managed Pipeline mode.
Check the httpHandlers configuration in IIS. Try following:
1. Open Server Manager
2. Select Roles>Web Server (IIS)>IIS Manager>Select the Server>Applocation Pools
3. Select the appPool that your asp.net app is running under>Click on 'Advanced Settings' from the right hand pane.
4. Under Advanced Settings>General>Managed Pipeline Mode, select "Classic"
5. Recycle app pool and test your app.

You will need to open IIS manager, and go to the Application Pool for your site.
Change the properties of the application pool from "Integrated" to "Classic".

Hope this helps!

Also, if you want to remain in integrated mode, please use the instructions in the custom-error message and also in
this blog post to migrate the handler/module entries to the new section.

Do I need to be logged in as Administrator, or can I be logged as a User with Admin rights ?

The above answers which refer to reverting to Classic mode may be adequate solutions for many cases, however it is possible to fix this problem while keeping your app pool in integrated mode, which may be desirable for many scenarios (such as when impersonation
is being used to authenticate).
To fix this while maintaining integrated mode, add the following markup to your application's web.config in the configuration section:
<validation validateIntegratedModeConfiguration="false" />
