How Can I Prevent Writing to the Root of C: Drive?
Asked by

I'm trying to secure shared devices in our environment by preventing users from writing files to the root of the C: drive. We have these devices set up with the Shared multi-user Device policy in Intune, and any files in user profiles get deleted after sign out. I thought it would be straightforward to limit writing access, but I've hit a wall. I can adjust permissions, but I'm worried that could lead to problems. I even attempted to hide the C: drive through policy, but that didn't work as expected. Does anyone have advice on how to effectively restrict writing to the C: drive?

It sounds like you're on the right track. By default, users shouldn't be able to write to the C: drive unless they're admins. One way to enhance security is to remove 'Authenticated Users' from the permissions on the root of C: so they can't create folders there. You can use a PowerShell script to adjust the ACLs and remove the AppendData right for that group. Just make sure you're careful not to mess with admin rights or system permissions.
