ok sir i now perform a clean install.. but again unknown device appeared on my device manager and seems quick launch buttons software will remove this unknown device.. i will not install quick launch buttons for now. til i found a driver on this unknown device without the quick launch...
the annoying message says "do you want to start hp quick launch buttons", there's an option to run or to quit or something else. does this has something to do with the test mode issue? im using vista drivers of course
May you guys enlighten me on what to install on HP 520 after installing windows 7. i installed hp quick launch buttons coz something appears on my device manager. but there is always annoying message in my start up. is there an hp quick launch buttons driver that is compatible with windows...
