The CrowdStrike Windows outage that hit the world this week stems back to an EU-Microsoft deal from 2009 that meant Microsoft had to give antivirus vendors the same Windows API access it had.
The Windows Hardware Certification program (formerly Windows Hardware Quality Labs Testing, WHQL Testing, or Windows Logo Testing) is Microsoft’s testing process which involves running a series of tests on third-party device drivers, and then submitting the log files from these tests to Microsoft for review. The procedure may also include Microsoft running their own tests on a wide range of equipment, such as different hardware and different Microsoft Windows editions.
