I try to be up to date for VS Version.
My projects are C# project (console and library).
It seem to occur randomly. So I don't have a scenario. Should I find one, I will let known.
Thanks for your answer @Anna Xiu-MSFT

Customize Visual Studio Window Title 4.0
This lightweight extension allows changing the window title of Visual Studio to include a folder tree with a configurable min depth and max depth distance from the solution/project file, and the use of special tags to help with many other possible scenarios (Git, Hg, TFS, SVN...).
Solution-specific overriding rules are available as well to cover virtually any possible renaming needs. It can also be configured so that the rules apply only when at least two instances of Visual Studio are running with the same window title.
This is particularly useful when branching a solution/project: it becomes possible to easily identify which branch you are working on, in case both would have the same solution/project name.
