In a recipe I can use registry\_value\_exists? to see if a registry value  
exists, but when I try to use the same method in a resource provider I get  
a NoMethodError. How do I check if a registry value exists from within a  
provider?

In your provider class, you should be able to 'include  
Chef::DSL::RegistryHelper' to gain access to those same methods within your  
provider.
