> What if you have two different project with different requirements at the same time?
Install multiple versions of Windows SDK. They co-exist just fine; new versions don’t replace old ones. When I was an independent contractor, I had 4 versions of visual studio and 10 versions of windows SDK all installed at once, different projects used different ones.
Windows SDKs, WDKs (driver dev), Visual Studio releases, and .NET SDKs all coexist peacefully on a machine. If a project build breaks due to newer SDKs, it's because it was configured with "use newest version". (Which is usually fine but sometimes requires pinning if you're using more "niche" things like WDK)
Every language should have a tool like Python uv.
