How to list the ASP.NET framework of all web sites in IIS

If you want to list the ASP.NET framework version for all IIS web sites on a server, use the command below.

C:\WINDOWS\microsoft.net\Framework\v4.0.30319>aspnet_regiis.exe -lk

From the help text: "This will list all the path of all IIS metabase keys where ASP.NET is scriptmapped, together with the version. Keys that inherit ASP.NET scriptmaps from a parent key will not be displayed."
