Anyone else tracking the latest Windows kernel changes? Microsoft finally pulled the plug on trust for cross-signed root program drivers. If you have been relying on ancient, leaked certs or low-effort manual mapping to get your kernel driver loaded, expect a massive headache on updated systems.
Tech-wise, this is a clear shift to force everyone into the WHCP ecosystem. For those of us dealing with Ring 0, the days of throwing a generic signed driver at the loader and hoping for the best are numbered.
Most of the "paste and pray" crowd using low-tier loaders are going to get hit with wave after wave of manual bans or just straight-up loading failures. We are reaching a point where if you are not running a legitimate, properly signed driver or moving to a DMA setup (with custom FW, obviously), you are basically begging for an HWID ban.
I am curious to see how the devs who rely on public vulnerable driver exploits handle this once the latest cumulative updates hit the general user base. Are we looking at a permanent shift toward EFI-level loaders, or are people just going to double down on finding new signing exploits?
Let me know if anyone has tested their current loaders on the latest Insider builds—I have a feeling a lot of stuff is already breaking. How are you guys planning to mitigate this without going full EV-sign?

- The Impact: Any driver utilizing deprecated cross-signed certificates will likely fail to load or trigger immediate system instability/BSOD on newer builds.
- The Barrier: This isn't just about loading anymore; it's about persistent kernel integrity. If your project relies on a vulnerable driver (the classic "bring your own vulnerable driver" approach), you are going to see significantly higher detection rates as the OS becomes increasingly hostile to unsigned or poorly signed entities.
- The Future: Most P2C providers are going to have to pivot hard to custom, EV-signed drivers or move further into the hypervisor/DMA space to maintain an undetected status.
