That's still writing new code. Also, its kind of an extremely bad idea to do that because how are you going to test it? If you have to rewrite anything (hint: you probably don't) its best to do it incrementally over time because of the QA and stakeholder alignment overhead. You cannot push things into production unless it works as its users are expecting and it does exactly what stakeholders expect as well.

If it is Windows, then you and I are going to test it :)

No no, your talking common sense and logic. You can't think like that. You have to think "How do I rush out as much code as possible?" After all, this is MS we're talking about, and Windows 11 is totally the shining example of amazing and completely stable code. /s
