Must Succeed Pool...DEAD!

When allocating pool, do not specify pool type NonPagedPoolMustSucceed. In XP, this pool type has been declared reserved, and can legally be used only to support the boot-up process. Attempts to use Must Succeed pool on XP will be "caught" by Driver Verifier.

Start updating your drivers now. Must Succeed pool is out. If you get a failure, you can either retry or fail the operating you're trying to perform in your driver. Yeah, I know it's annoying. But my sources tell me people were using this feature gratuitously, leading to unnecessary O/S bug checks. What's that you guys say about "one bad apple"?
