I have always been a proponent of using Appverifier whenever you are debugging your code with Windbg, but lets say you keep hitting verifier breaks in other modules that you aren't currently trying to debug. Aside from being a good practice to fix all verifier breaks, and it is good to help other teams debug their components, sometimes you just want those breaks to go away to you can focus on your code. After enabling Appverifier, you can do just that in the debugger.
Lets say you only care about foo.dll. This is how you can have verifier only enabled on that module.
0:005> !avrf -skp all
Verifier package version >= 3.00
Exclusion ranges and suspend period have been reset.
0:005> !avrf -trg foo
It is that simple.
