IIS 7.5 error: Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list

Today I installed Clean Windows Web Server 2008 R2 64-bit with IIS 7.5. To my surprise opening .NET 4.0 application I received the following error:
IIS 7.5 Detailed Error - 500.21 - Internal Server Error






As it turns out, some glitch caused this problem, and somehow .NET was not registered with IIS.
Running the following commands solved this issue:
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
