PENDING Package to disable Windows Recovery Environment

[Kave70]

We have recently discovered that students are able to access the recovery environment and wipe out our image. In Windows 10 they simply have to hold down the shift button and restart it. In the future I will disable this function in my image, but I need to hit 2000 student machines now with the fix.
I know the answer to this issue is to run the command reagentc.exe /disable

How can I do this through sccm?
I tried making a package with no program attached, simply the command. My test machines all failed.
Any other suggestions?
Thanking you in advance for any help.

The command that you are using is correct. I wonder why isn't the package running.

I'm not sure- will work on it again this afternoon. If I see my mistake, I'll be sure to post.

I don't know what the issue was, but I deleted that packaged and made another one, with the same command- it worked.
