Report #29025

[bug\_fix] linker \`link.exe\` not found

Install the Visual C\+\+ Build Tools or full Visual Studio with the 'Desktop development with C\+\+' workload, ensuring the Windows SDK is selected. Alternatively, switch to the GNU toolchain by running \`rustup default stable-x86\_64-pc-windows-gnu\` \(requires MinGW\). The root cause is that the Rust MSVC target requires the Microsoft linker \(link.exe\) which is not included in the Windows base installation or rustup; it must be obtained from Microsoft's C\+\+ build tooling.

Journey Context:
You're on a fresh Windows 10 or 11 machine. You download rustup-init.exe, run it with default settings, then \`cargo new hello\_world\` and \`cargo build\`. Instead of success, you get a long error ending with 'linker \`link.exe\` not found'. You check your PATH and don't see anything wrong. You search the error and find it's a missing Visual Studio component. You download the Build Tools for Visual Studio installer from microsoft.com, select 'Desktop development with C\+\+', wait for the multi-gigabyte install, then reboot. After that, \`cargo build\` successfully links the executable. Alternatively, you might have switched to the GNU toolchain to avoid the MSVC dependency entirely.
