Which Driver Should You Download?
These SoftPaqs are compiled exclusively for Windows 7 32-bit. Do not attempt to install them on Windows 7 64-bit, Windows 8, or newer operating systems. Using the wrong architecture can leave devices non-functional or cause system instability.
Driver Availability Note
All download links point to the original HP SoftPaq repositories. These are the last official releases for the CQ20. If a link fails, the file may have been removed from HP’s servers — search for the SoftPaq ID (for example sp45115) on trusted archives.
