Hi, I'm Garrett, Principal PM on the Windows Hardware Program. If you're a partner having trouble regaining access to Hardware Dev Center after account verification, we've put a temporary process in place to speed up reinstatement. You can learn more at aka.ms/HDC-Account-Verificat…

Driver Signing Judgment Day Update For anyone still stuck in driver signing limbo there's new guidance for how to get out on the HDC blog: techcommunity.microsoft.com/… And if THAT doesn't help there's a form to fill our to expedite your review: forms.cloud.microsoft/Pages/… Given that our account is reinstated already we have no experience going these routes. We'll continue to keep the visibility up so let us know if you have any success or trouble...

And we're back to being able to sign and release our drivers 🙌 Thanks to @shanselman (and others at MS) for helping to expedite. We're looking for guidance on how folks should escalate their current dashboard access issues. Will update once we know more...

After 30 years of signing windows drivers, we have been locked out of driver signing like many other companies. In a word, the disrespect and disregard with which MSFT is treating IHVs and ISVs is stunning. Don’t let anyone tell you it’s because we didn’t read our emails or submit the right verification paperwork. Cuz we did all that back in October. And this month, we were suddenly and without any warning locked out. Support said they’d “do their best” to let us know “within 90 days” if we’re good enough to get back on. In the meantime, many thousands of desktops and instruments are not being updated, cuz we can’t sign drivers. Awesome job, Microsoft. Thanks.

Update regarding Driver Verifier not working in Windows 11: It seems like this "not working" behavior is restricted to when you enable DV via the GUI interface. If you use the command line it works as it should! Updated blog post: osr.com/blog/2024/05/09/huge…

Driver Verifier, everyone's favorite tool for driver quality, is effectively broken in Windows 11. Seriously. osr.com/blog/2024/05/09/huge…

Microsoft: No more driver updates to be allowed for Win 7, Win 8, and Win 8.1 -- Cross-Signing will be discontinued. I wish I were joking. We HAVE to push back on this and get them to change the plan. osr.com/blog/2020/10/15/micr…

The WDK for 20H1 defines new functions for auto-zeroing pool allocations, such as ExAllocarePoolZero. But... a serious WDK bug causses security vulnerability and crashes when using these functions on Windows 1909. See more at osr.com/blog/2020/07/14/bug-…

Driver Devs: DO NOT update VS 2019 beyond 16.4.0, or you risk breaking the WDK, to the point that it won’t compile anything when Code Analysis is enabled (and you can’t subsequently turn off Code Analysis). Details here: osr.com/blog/2020/03/31/bewa…
