+# *-win7-windows-msvc
+
+**Tier: 3**
+
+Windows targets continuing support of windows7.
+
+## Target maintainers
+
+- @roblabla
+
+## Requirements
+
+This target supports full the entirety of std. This is automatically tested
+every night on private infrastructure. Host tools may also work, though those
+are not currently tested.
+
+Those targets follow Windows calling convention for extern "C".
+
+Like with any other Windows target created binaries are in PE format.
+
+## Building the target
+
+You can build Rust with support for the targets by adding it to the target list in config.toml:
+
+```toml
+[build]
+build-stage = 1
+target = [ "x86_64-win7-windows-msvc" ]
+```
+
+## Building Rust programs
+
+Rust does not yet ship pre-compiled artifacts for this target. To compile for
+this target, you will either need to build Rust with the target enabled (see
+"Building the target" above), or build your own copy of `core` by using
+`build-std` or similar.
+
+## Testing
+
+Created binaries work fine on Windows or Wine using native hardware.
+
+## Cross-compilation toolchains and C code
+
+Compatible C code can be built with either MSVC's `cl.exe` or LLVM's clang-cl.
