My modifications to InitialStore.xml don't seem to take effect

I wanted to allow a colleague access to my Hyper-V. Following the instructions at  https://blogs.technet.com/jhoward/archive/2008/03/28/part-1-hyper-v-remote-management-you-do-not-have-the-requested-permission-to-complete-this-task-contact-the-administrator-of-the-authorization-policy-for-the-computer-computername.aspx

I used Azman.msc to modify \ProgramData\Microsoft\Windows\Hyper-V\InitalStore.xml.

However, nothing I changed seemed to take effect. Even after I rebooted the host, nothing changed.

Eventually, I figured out that SCVMM has redirected the Store to \ProgramData\Microsoft\Virtual Machine Manager\HyperVAuthStore.xml

I decided to not modify the access rights here, but created a user in SCVMM.
