This is an administrator command-line tool that removes a system mandatory label from an NTFS drive, folder or file. Use this if you get an "Error 0x80070522: Required privilege not held by the client" message trying to save or copy to a NTFS directory.
Usage: SystemMandatoryLabelRemover {--help | --test <file> | --clear <file>}.
--help: Shows this help screen.
--test <file>: Try to access and print out the system mandatory label of <file>.
--clear <file>: Removes an existing system mandatory label from <file>.
Normally we should be able to do this with icacls, but it only allows us to change the level, not remove the label entirely. This leaves us with side effects like executables in the affected folders unable to access the user directory to store settings.
The download is to the right under "Releases". 😉
