Resolved SCCM 2012 R2 - BITs Installed/Enabled Warning & Microsoft Remote Differential Compression (RDC) library failed

These are some of the of other warning I received while installing  SCCM 2012 R2, First one is
Bits Installed Warning. / Bits Enabled Warning.
Background Intelligent Transfer Service (BITS) is required for the management point and distribution point site system roles. BITS is not installed, IIS 6 WMI compatibility component for IIS7 is not installed on this computer or the remote IIS host, or Setup was unable to verify remote IIS settings because IIS common components were not installed on the site server computer. Also, check if IIS/BITS services are running properly. Setup cannot continue until BITS is installed and enabled in the IIS settings.


When I checked IIS services components I found I have already IIS 6 WMI compatibility. but still was getting warning because BITs was not installed., To install BITs right click features in server manager, right click features and Add feature, then select feature Background Intelligent Transfer Services (BITS), once you check the box of BITS another additional extensions for IIS box will pop up (Add Required Role Services). Click it and install all required Features.

Once I run check all my warning related to Bits has been gone.
Then next failed item is Microsoft Remote Differential Compression (RDC) library registered Failed
Microsoft Remote Differential Compression (RDC) library must be registered for Configuration Manager site server installation. Details at http://technet.microsoft.com/library/cc431377.aspx#RDC_for_Site_Servers.
The same way we installed BITS, We have add Remote Differential Compression Feature and Run Check on SCCM installation page, error will be gone.
Below is the explanation from Microsoft about the features I installed as Prerequisite for SCCM

The Remote Differential Compression (RDC) feature is a set of application programming interfaces (APIs) that applications can use to determine if a set of files have changed, and if so, to detect which portions of the files contain the changes. RDC detects insertions, removals, and rearrangements of data in files, which enables an application to replicate only the changed portions of a file. This is useful when replicating files over a limited-bandwidth network such as a wide area network (WAN) connection. 
Use Background Intelligent Transfer Service (BITS) to transfer files asynchronously between a client and a server.
