I am using Microsoft Visual Studio Professional 2017. I installed KDiff3 compare tool (version 0.9.98) in in my local machine. Now, by default, file comparison (.cs extension) in Visual Studio is happening in KDiff, unlike earlier when it used to open in the native Compare and Merge tool of Visual Studio. I want the previous tool back. Is there any way to change the default comparison tool for Visual Studio from KDiff3 to the TFS Compare and Merge tool? I checked Tools -> Options... -> Source Control -> Visual Studio Team Foundation Server -> Configure User Tools but nothing is configured here.

enter image description here

I googled this issue and I am getting multiple articles on how to configure a third party tool such as WinMerge or BeyondCompare for comparison but there are no articles on how to remove any existing tool to restore the original Visual Studio comparison tool. Any help would be highly appreciated.
