I created a custom Program Files folder on my new drive, trying to mirror the permissions and security settings of the default Program Files on my C drive. Now every time I try to access anything on this new drive, I'm prompted for permission, which is a hassle. I'm currently working on a project in 3ds Max, and it won't even save in this new folder. I've attempted to reset the settings using the command prompt, but nothing has changed. How can I revert the security settings back to default?

You might want to delete that custom Program Files folder you created. The default folder on the C drive has important hidden files that help programs function properly. Also, try running the 'sfc /scannow' command; it can help restore any corrupted files on your C drive.
I'm curious why you felt the need to create your own Program Files folder? Did you by chance delete the existing one?
I had to, my C drive was almost full! I thought it made sense to have both drives with the same settings for installing programs.
Which version of Windows are you using? If you're on Professional or above, there’s a 'Security' tab in Explorer that can help you fix these issues. If you're on Home Edition, you'll likely need to run a command line to sort it out. Just be careful, tweaking the ACLs on the wrong folder can lead to bigger problems!

I messed up the security settings on my whole new drive, so now every folder is asking for permission, not just the Program Files.
