Large mature systems often contain symbols that are no longer used. These may be methods that are no longer called or variables and data structures that are no longer referenced by active logic. These unused symbols are often referred to as "dead code, dead wood, Cruft". Dead code make a system "smell bad" and a form of technical debt, and it can be difficult to identify and risky to remove.  An Upgrade Project is an optimal time to deal with dead code because gmStudio can help you identify and remove it.

I just had a customer ask me about the future of COM support on Windows.  Here is how I responded

Someone mentioned they had heard the VB6 runtime will not be supported beyond Windows10 (2025?).  I could not find any official word on that.  But I know there is no support statement for VB6 on Windows 11 -- but that is not an official Windows release yet, so...  

One thing: COM is a typically 32-bit technology and special steps are needed to work on 64-bit.  On 64bit, which is what most Windows installations are running any more, COM must run in a 32-bit emulation.  Maybe you have noticed VB6 COM references need to be to files in the SysWOW64 folder, not the System32 folder... 

Bottom line, VB6 and COM may be officially supported by Microsoft, but they are not mainstream anymore.  As time goes on, you are more likely to run into difficult issues with them; you will find yourself in troubled waters, in a boat by yourself without a paddle... And more importantly, all VB6 programmers will eventually leave the labor pool.  Organizations still running VB6 will have no one to go to for help when they have technical problems.  Organizations may choose to bear that risk and continue to put out VB6/COM compatibility fires as they come up, or they can upgrade their systems and join the much larger community of .NET/C# developers on a vital, well-supported platform. 

To give you an idea about the level of interest in VB6 vs C# here are some relevant metrics:

Google Search (June 2021)

GitHub (Jan 2022)

Here are some details on VB6 support from Microsoft.

gmBasic: Upgrade Engine

Based on feedback from our clients and migration projects in the field, we are continuously improving gmBasic so as to help users more easily produce cleaner and more correct results. Most recently, this work changes how the tool is extended to perform advanced upgrade analysis and transformation. This distribution, Version 40.03, includes several enhancements:

• Improves gmSL, gmAPI, and Migration Utility frameworks for integrating custom migration and reporting rules with the Upgrade Engine.

• Several Migration Utilities, implemented in gmAPI/C#, are now part of the standard distribution:
  • gmCodeStyle.exe implements the custom coding style transformations
