Windows XP is not a supported platform, but all newer Windows should be able to build the JDK.
On Windows, it is important that you pay attention to the instructions in the Special Considerations.
-Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layers are Cygwin and Windows Subsystem for Linux (WSL). (Msys is no longer supported due to a too old bash; msys2 would likely be possible to support in a future version but that would require effort to implement.)

Currently, the only supported such layers are Cygwin, Windows Subsystem for Linux (WSL), and MSYS2. (MSYS is no longer supported due to an outdated bash; While OpenJDK can be built with MSYS2, support for it is still experimental, so build failures and unusual errors are not uncommon.)
Internally in the build system, all paths are represented as Unix-style paths, e.g. /cygdrive/c/git/jdk/Makefile rather than C:\git\jdk\Makefile. This rule also applies to input to the build system, e.g. in arguments to configure. So, use --with-msvcr-dll=/cygdrive/c/msvcr100.dll rather than --with-msvcr-dll=c:\msvcr100.dll. For details on this conversion, see the section on Fixpath.
A functioning Cygwin environment is required for building the JDK on Windows. If you have a 64-bit OS, we strongly recommend using the 64-bit version of Cygwin.

To use a specific version of Xcode, use xcode-select -s before running configure, or use --with-toolchain-path to point to the version of Xcode to use, e.g. configure --with-toolchain-path=/Applications/Xcode8.app/Contents/Developer/usr/bin
If you have recently (inadvertently) updated your OS and/or Xcode version, and the JDK can no longer be built, please see the section on Problems with the Build Environment, and Getting Help to find out if there are any recent, non-merged patches available for this update.
For aarch64 machines running Windows the minimum accepted version is Visual Studio 2019 (16.8 or higher). For all other platforms the minimum accepted version of Visual Studio is 2017. Older versions will not be accepted by configure and will not work. For all platforms the maximum accepted version of Visual Studio is 2022.

If you have multiple versions of Visual Studio installed, configure will by default pick the latest. You can request a specific version to be used by setting --with-toolchain-version, e.g. --with-toolchain-version=2017.
If you have Visual Studio installed but configure fails to detect it, it may be because of spaces in path.
