WinSys is a sysinfo plugin for XChat-WDK. It uses highly Windows-specific code to display some info about your hardware and OS. Using WinSys is really simple: just click on Window -> Display System Info, or type
And the info will be printed out. If you're on a server tab, it gets printed out line by line (and will be visible only to you), but if you're in a channel or private conversation, it's shortened to just one line to avoid spam.
The first execution takes a few seconds to finish, but from then static information is cached so additional executions should be instantaneous.
The source code is available in the repo.
