Re: Vintage: SRX-99, can't make special keys (volume, brightness) functions in Windows XP.

Hi Keyreel,

Thank you for the clarifications, I see what you're saying about the link that shows Windows 7 when you clicked on it. Please refer to this link to check the list of the compatible drivers and software for your laptop, https://esupport.sony.com/US/p/model-home.pl?mdl=PCGSRX99&template_id=1&region_id=1&tab=download#/downloadTab

Look for the UPDATE Sony® Notebook Setup Update Utility or simply clicked on the update.

I hope this helps.

Regards,
Jen
