KB5002653 issue with the Kernel Function GetCommandLineW

Thank you for clarifying the nature of the main problem: the missing command line arguments, such as /parameter, and not just the handling of quotes. The problem seems to be deeper and probably rooted in how Windows or Excel interpret command line input after KB5002653.

A patch provided by Microsoft to fix or reverse this behavior would be the optimal solution. Until then, unfortunately, I have not offered any other solution suggestion or workaround.

Unfortunately, as you noted, the only effective solution so far may be to uninstall KB5002653 if possible, especially if you are using an older version of Excel (such as Excel 2016). This is not ideal for long-term stability or security, so it should be approached with caution.

Hope that maybe someone here in the forum knows another workaround or solution and can help you out.

I wish you all the best in your endeavors.
