Report #62390

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

Install the Visual Studio Build Tools \(not just VS Code\) with the 'Desktop development with C\+\+' workload, which provides \`link.exe\` and the Windows SDK. Alternatively, switch to the GNU toolchain by running \`rustup default stable-x86\_64-pc-windows-gnu\` and installing MinGW-w64.

Journey Context:
You install Rust via rustup on a fresh Windows 11 machine, open PowerShell, run \`cargo new hello\_world\` and \`cargo build\`. Instead of success, you get a cryptic error that the linker \`link.exe\` was not found. You search online and find suggestions to install Visual Studio, so you download VS Community, but the error persists because you only installed the '.NET desktop development' workload, not the C\+\+ tools. You try installing 'MSVC v143' individually from the VS Installer, but still fail because the Windows SDK is missing. After several hours of reinstalling, you realize you must check the specific 'Desktop development with C\+\+' workload checkbox which bundles the Windows SDK, C\+\+ build tools, and \`link.exe\` into a single install. If you prefer not to install several gigabytes of MSVC, you discover you can switch to the \`x86\_64-pc-windows-gnu\` target which uses the MinGW linker instead.
