# Sample Policy
Below is a sample policy that allows kernel debuggers, PowerShell ISE, and Registry Editor. It also demonstrates how to specify your organization's code signing and policy signing certificates.

# Policy Removal
> [!Note] There is currently a policy deletion error, with a fix expected in the 2D update in late February 2020. Devices of users who are unenrolled will still have their WDAC policies removed. In the mentime, IT Pros are recommended to update their policy with the below 'empty' policy which makes no changes to S mode.
