-## Building for 32-bit Windows
-
-To build executables for Windows 32-bit, install the following dependencies:
-
-    sudo apt install g++-mingw-w64-i686 mingw-w64-i686-dev
-
-For Ubuntu Bionic 18.04 and Windows Subsystem for Linux <sup>[1](#footnote1)</sup>:
-
-    sudo update-alternatives --config i686-w64-mingw32-g++  # Set the default mingw32 g++ compiler option to posix.
-
-Note that for WSL the Bitcoin Core source path MUST be somewhere in the default mount file system, for
-example /usr/src/bitcoin, AND not under /mnt/d/. If this is not the case the dependency autoconf scripts will fail.
-This means you cannot use a directory that located directly on the host Windows file system to perform the build.
-
-Build using:
-
-    PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g') # strip out problematic Windows %PATH% imported var
-    cd depends
-    make HOST=i686-w64-mingw32
-    cd ..
-    ./autogen.sh # not required when building from tarball
-    CONFIG_SITE=$PWD/depends/i686-w64-mingw32/share/config.site ./configure --prefix=/
-    make
