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.
For the Nth time, crowdstrike circumvented the testing process
Edit: this is not to say that cs didn’t have to in order to provide their services, nor is this to say that ms didn’t know about the circumvention and/or delegate testing of config files to CS. I’ll take any opportunity to rag on MS, but in this case it is entirely on CS.
I had a read about the WHQL (which I assumes what certified means). It uses the Windows HLK to perform a series of tests, which submited to Microsoft, and only then the driver will be signed.
While certification isn’t endorsement, the testing and the resulting certification implies basic compatibility and reliability. And causing bootloops and BSODs is anywhere but close to “basic compatibility and reliability.”
Crowdstrike bypassed WHQL because the update was not to the driver, it was to a configuration file that then gets ingested by the driver. It’s deliberate so they can push out updates for developing threats without being slowed down by the WHQL process.
And that means when they decide to just send it on a Friday with a buggy config file, nobody is responsible but Crowdstrike.
Certifying a driver is not an endorsement.
It is a verification that it is legitimately from who it claims to be from. Microsoft has zero fault, period.

Oh wow. Then definitely CS is in fault. What a brilliant idea they have.
