Hi all,

Nice to meet you guys. I have an urgent problem. My office is going to use Windows 8 64-bit Enterprise English for all the new machine. As for my colleagues operation needs, we will use Adobe Reader 9 as the default PDF reader. And in order to ease my workload, I would like to modify registry for setting the default PDF reader in a system startup script. The problem now is that it contains a value called "hash" which I have no idea of computing it. I would like to know whether there are still other ways to use automations or GPO for this task so that I do not need to set this for all (about 160) of my colleagues individually.

Thank you!
