whql what does is mean
Windows Hardware Quality Labs testing or WHQL Testing is Microsoft 's testing process which involves running a series of tests on third-party hardware or software, and then submitting the log files from these tests to Microsoft for review.hen Windows XP detects a new device for which it does not have built-in drivers, it will show a Found New Hardware Wizard (see screenshot on the right). One way to avoid the Found New Hardware Wizard from popping up on Windows XP is by pre-installing a WHQL certified driver before the device is plugged in.
