I do not recomend to use 'srvany.exe' to make Perl system running as services for 2 reasons:

1o. System running as a services is little be different of normal system, and if we use one external program to run as a service we don't take care about this difference
2o. It's so easy to use Win32::Daemon module, and you can take control of Services Queue Message, where you can do something before stop services or shutdown Windows.

On my opinion, if we don't want take care about extra coding we can use the Windows Schedule. I think it's better than use 'srvany.exe'.

That's my opinion
