Unlike *nix platforms, system services on Windows must be specifically designed to run as services, and written against the Win32 Service APIs. This creates a problem when it is desired to run a program as a Windows system service which was not designed to function in this role.
SRVANY.EXE is an executable distributed by Microsoft in the Windows NT 4.0
Resource Kit, which can be used to adapt any program into a system service.
SRVANY.EXE is configured as the system service, and it spawns and supervises
the target process in turn. Thus, it forms an adapter between the Windows
service manager and arbitrary programs. However,
SRVANY is a proprietary
binary for which source code is not available, and is no longer even
distributed by Microsoft.
winsvcwrap is a simple open source Go
program to replace
SRVANY and provide equivalent functionality, and is now
used by the Namecoin project to power its Windows installer bundle. This
enables the Namecoin project to avoid depending on an unmaintained proprietary
component. It can be used by anyone seeking to run arbitrary Windows programs
as Windows system services. Since it is written in Go, it is memory-safe
(unlike C/C++) and bootstrappable (unlike Rust).
