Tried that. However it freezes on sending data. A mini window with "sending data" message pops-up. And nothing happens... after a while (10 minutes) you must click storno (zrušit in Czech), to be able to use steam. So there's a problem even with a manual process, since my steam version is current and yes, I've tried to restart Steam a repeated the process.
So there are two ways to falsify Steam HW survey - it does not pop-up automatically anytime the PC configuration changes, is not mandatory and even if you call it manually, it does not mean the data get sent. And as stated above, data processing is suspected too.
