As we have moved through Group Policy and taken a look at numerous screenshots, you may have noticed some comment fields. Primarily used inside the GPOs, these comments can prove to be invaluable to other administrators who are filling your shoes for a day. Commenting inside policies will also become useful to your future self when you find yourself opening up a policy 2, 3, or 10 years down the road and wondering why in the world you implemented those settings in the first place.

Let's take a look at the places where we can insert comments into GPOs. Launch the GPMC with me, and expand out the Group Policy Objects folder so that we can view all of the GPOs that we have created throughout this book. Then, Edit a GPO to launch GPME. I am going to edit my GPO called Auto-launch Notepad+Calc on login. This policy is already aptly named so that anyone who looks at this policy will be able to guess exactly what it is doing, but we'll flesh out a comment in here anyway to give even more information.

The option to add comments is listed inside each policy setting. So, in order to add a comment appropriate for my policy, I will need to re-navigate to the location of my Run these programs at user logon setting, and double-click on that setting in order to edit it. This is exactly the same screen where we went to create this policy in the first place, so you can see how it makes the most sense to add in these comments on day one, immediately when creating the policy and plugging settings into it.

I am simply going to populate the Comment field with a little bit of useful information. I like to include the date and my initials with the comment. That way, other administrators who log in here and take a look at your policy will have a clear idea about who created this, when they created it, and for what purpose. It is also helpful to include your initials here for searching purposes, which we will review later in this chapter:
